The difference between nanoparticles and nanomaterials

Posted on by adminLeave a comment
What is nanopowder? Nanopowder It is also known as nanoparticle and refers to ultrafine particle sizes between 1-100nm. Some people refer to it as ultrafine particle. It is bigger than atomic particles and smaller than normal particles. Nanoparticles are absorbed into the body by the outer layer, such as the skin or the lungs. The amount of migration they undergo from the exterior to the internal depends on their physical and chemical properties.
What’s the difference between nanomaterials & nanoparticles
Nanomaterials Refers to materials that are in the nanoscale (1nm100nm), in at most one dimension, in three-dimensional space. They can also be composed of these basic units. The particle diameter of 10 nanometers contains 4000 molecules and the surface-atoms are 40%. For a particle with a diameter of 1 nanometer it contains 30 molecules and the surface-atoms are 99%.

Introduction of Nano Cobalt Powder
Nano cobalt is a powder that can be gray, black or spherical. Cobalt Nanoparticles can be used for a variety applications, such as sensors, imaging and more. Cobalt is classified as a hazardous substance and can cause skin allergies. Inhalation has been shown to cause breathing difficulties and asthma symptoms.
Laser evaporation creates spherical metal particles. Cobalt does not have a high abundance, but it is found widely in soil, rocks, mineral water and oceans, as well as in meteorites, sunlight, star atmosphere and coal.

Applications of nanocobalt particles
1. Medical sensors
2. Magnetic resonance imaging for biomedical applications
3. Agents of targeted drug delivery for cancer treatment
4. Coatings for textiles, high-performance magnetic recording material, nanofibers and nanowires

What are nanoparticles, and how are they used? Nanoparticles The use of ceramic coatings in solar cells, scratchproof eyeglasses (and other products) is increasing.

What is a Nanoparticle?
Nanoparticles or ultrafine particles are defined as a matter particle that has a diameter of between 1 and 10 nanometres. The term is also used to refer to larger particles (up 500 nm) or fibers or tubes with a diameter less than 100nm in just two directions.

What is the effect of nanoparticles in the body on health?
Inhalation of a substance can cause adverse reactions Nanoparticles Inflammation of the lungs and heart problems are possible. Human studies show that breathing soot triggers a generalized inflammatory response, and changes the system which regulates involuntary cardiovascular functions such as heart rate control.

What are examples nanoparticles of?
There are two types of nanoparticles: hard (e.g. titania, silicon dioxide, fullerenes), and soft (e.g. liposomes.
Some of the most common food products that contain nanotechnology are candies (M&M’s and Skittles), plastic containers, and baby bottles.

Nanomaterials also have many applications in medicine and bioengineering.Targeting drugs with nanometer magnetic materials as drug carriers have been successfully developed, which are called “biological missiles”.In other words, drugs are carried on the protein surface coated by magnetic Fe3O4 nanoparticles, injected into human blood vessels, and delivered to the lesion site through magnetic navigation to release drugs, which can reduce the side effects caused by drugs in the liver, spleen, kidney, etc.The information of various biochemical reactions and electrochemical information can be obtained by using nanosensors.Nanoparticles can be used as a nano robot, into the person’s blood, to human body health checks, dredge in cerebral thrombosis, remove fat deposits in the heart arteries, viruses, and even can eat kill cancer cells, etc., can be predicted that with the development of the preparation of nanometer materials technology development and function, there will be more and more new nano material has been widely used in many high-tech fields.

The growth of gold nanoparticles within tumors can help fight cancer
In many studies, gold has shown to be effective at fighting cancer. Researchers have developed a method to grow gold nanoparticles within cancer cells. They can aid in imaging, and they can even be heated to kill the tumours.

Previously, nanotubes, gold nanostars and other nanoparticles were used to battle cancer. However, one of the major challenges is getting these nanoparticles inside tumors. They can be equipped with peptides which hunt down the cancer or they can sneak inside by attaching themselves to white blood cell.
Researchers found that they could grow gold inside cancer cells. This method is quicker and doesn’t need as much gold.

The team used PEG as a vehicle for ionic Gold, which is basically gold salts dispersed in a liquid. When the acidic cellular environment is exposed to this, it converts the ionic gold into plasmonic gold particles. The team claims that this can be done in just 30 minutes. It is much faster than traditional treatments which take up to 24 or more hours.

What are gold nanoparticles used for?

Posted on by adminLeave a comment
What exactly is colloidal or sol gold? It is a colloidal suspension (or colloidal solution) of nanoparticles of gold in fluid (usually water). Colloid colors are typically wine red for spherical particle sizes less than 100nm or blue/purple (for more spherical particles, or nanorods).

Property of Colloidal Gold
Colloid gold nanoparticle properties and applications are affected by their shape and size. A rod-shaped particle, for instance, has transverse and longitudinal absorption peaks. Their anisotropy will impact their ability to self-assemble.

How are gold nanoparticles utilized?
Drug delivery system
The biological distribution of drugs can be optimized to target diseased cells, tissues and organs with gold nanoparticles. If drug distribution is not sufficient, nanoparticles are able to deliver drugs. This includes targeting unstabil drugs like proteins, siRNA, and DNA. It also allows for drug delivery to more difficult locations (brain, retina or tumors). Their size and function determine the properties of nanoparticles. The properties of nanoparticles can also vary depending on their surface function and size. This is due to the variability in drug release or particle disintegration (e.g. biodegradable, sensitive to pH) An optimal nano-drug distribution system will ensure that active drug is accessible within the appropriate time and duration at the site of action. The concentration must be more than min. The effective concentration (MEC), should be lower than the min. Toxic concentrations (MTC)
For drugs like Paclitaxel, nanoparticles of gold are being investigated. Hydrophobic drugs can only be delivered by molecular packaging. The nanoparticles were found to have a high efficiency in bypassing the reticuloendothelial systems.

Enhancer for Radiotherapy
It has received a great deal of interest to use gold nanoparticles and others containing heavy elements to raise the dosage to cancer patients. Due to the fact that gold nanoparticles can absorb tumors more than those in healthy tissue, it is possible to increase the dose. Local deposition of radiation near nanoparticles seems to account for the biological effects of the treatment. It is similar to heavy ion therapy.

Toxic gases
Researchers developed an inexpensive and easy method of detecting hydrogen sulfide in the atmosphere based upon the anti-aggregation properties of gold nanoparticles. Hydrogen sulfide is dissected in an alkaline buffer solution. The solution creates HS,HS- which stabilises AuNPs. It also ensures they stay red. This permits visual assessment of hydrogen sulfide levels.

What do gold nanoparticles consist of?
Turkevich, et al.1951 devised a procedure for the production of AuNPs. This involved treating tetrachloroauric acids (HAuCl4) by boiling water with citric Acid. Citric acid is able to not only reduce but also act as a stabilizer. Frances modified the ratio of citric acid to gold to improve the process. It has been used extensively to produce moderately stable, spherical AuNPs. However, it is also capable of producing larger AuNPs (e.g. 100 nm).

Why is gold nanoparticles so red?
The visible spectrum is where gold nanoparticles have their resonance frequency. Because smaller gold nanoparticles are more sensitive to violet, blue, green, and yellow wavelengths they appear red.

Price for colloidal gold
Price is affected by many things, such as the demand and supply in the market and industry trends. Economic activity. Unexpected events.

How Can Gold Nanoparticles Be Used to Kill Bacteria

Posted on by adminLeave a comment
One team discovered that bacteria can be exposed to nanoparticles of gold, which causes their cells to burst and leak material, leading to death.


Each year, more than 25,000 people die from bacterial infection that cannot be treated with antibiotics. Drug resistance is increasing. Researchers are looking for other ways to combat the bacterial threat.
Since ancient Egyptian times gold has been used for many medical purposes. Recently, doctors have started to use gold to treat and diagnose cancer. It is an inert metallic that doesn’t react or change to contact with living organisms. It can be used in nanomedicine to make cancer cells grow.

New research has revealed a mechanism whereby gold nanoparticles kill bacteria.
The researchers made nanoparticles the size of stars and near perfect spheres in the lab. Each was approximately 100 nanometers across, which is one eighth of the width of a human hair.
“We found that the bacteria surrounding these nanoparticles started to deform, then deflated and finally died like an inflatable. Vladimir Baulin of University of Rovira Wilhelli Chemical engineering department said, “It seems that the cell wall explosion.”

This theory was tested by researchers who built bacteria models and observed the interactions of these bacteria with tiny gold particles measuring just 100 nanometers.
The results showed that the uniformity in the surface layers of these nanoparticles creates a mechanical force which stretches the cells of surrounding bacteria. This causes the bacteria to burst much like a balloon when it is stretched beyond its limits.

The study was performed by The Universitat Rovira I Virgili (Spanish), the University of Grenoble (France), and the Universitat der Saarlandes (German), RMIT University, Australia. The article was published in Advance Materials.

The gold nanoparticles, which are tiny particles made of gold, have a diameter between 1 and 100nm. They are highly electron dense, have dielectric properties and catalytic activity. They can bind with many biological macromolecules and not affect their biological activity.
Two types of gold nanoparticles are available: solid powder and liquid solution.
Solution of gold nanoparticles are sols that have been dispersed in an alkaline solution. The color of the nanoparticles depends on a variety of factors. Its color is determined by a number of factors. Smaller gold nanoparticles (2-5nm), medium-sized gold nanoparticles (10-20nm), appear wine red and larger gold particles (30-80nm), appear purplish. Additionally, it exhibits the characteristics of nanoparticles: quantum size effect; surface effect; volume effect; and macroscopic quant tunneling effect.

What is Colloidal Gold?

Posted on by adminLeave a comment
What is Colloidal Gold ? Colloidal Gold refers to a sol- or colloidal suspension made of gold nanoparticles in water. The most common colloids are wine red for spherical particle sizes less than 100nm and blue/purple for larger spherical particles, or nanorods. The optical, electronic, molecular recognition and molecular recognition properties of gold nanoparticles make them a subject of extensive research in many fields, including electronics, nanotechnology, biomedicine and electron microscopy.
The size and shape of colloidal silver nanoparticles are critical to their properties and their potential uses. The rod-like particles are characterized by transverse and longitudinal absorption peak structures, while anisotropy in shape can affect their self-assembly.

Because of the interaction between nanoparticles of visible light and colloidal gold, artists have been using it for centuries. Depending upon the particle size, shape, local index and state of aggregate, gold nanoparticles absorb light and produce colors that vary from bright red (smaller particles), to blue (larger ones), and finally transparent and uncolored (larger ones). These colors are due to a phenomenon known as local surface plasmon reflection (LSPR), where conducting electrons on the nanoparticles emit incident light.
In general, the wavelength of absorbed light increases as the nanoparticles get larger. For example, pseudospherical gold nanoparticles have a diameter of around 30 nm and peak LSPR absorbtion at approximately 530 nm.
A colloidal gold suspension may also cause apparent changes in color of the gold-nanoparticles solution. The optical properties and optical properties are dependent on the refractive indices near the nanoparticles’ surfaces. This means that two molecules (nanoparticles ligand and/or nanoparticles with solvent) can affect the observed optical characteristics. NP LSPR shifts to longer wavelengths when the refractive Index near the surface of gold increases. However, this is not possible in solvent environments. Nanoparticles can be coated non-conductive shells (biomolecules or alumina) to adjust the extinction peak.
Gold nanoparticles become more visible when they are aggregated. The optical properties of these particles change as the effective particle size, shape and dielectric environmental all change.

What does Colloidal Gold do?
Drug delivery system
Nanoparticles of gold can be used for optimizing the biological distribution drugs in diseased organs, tissues or cells. This will allow for better drug delivery. Only if drug distribution is insufficient, nanoparticle mediated drug Delivery is possible. Examples of this include drug targeting against stability (proteins, siRNA and DNA). Delivery to hard sites (brains, retinas, tumors, intracellular organismelles) and drugs with severe side effects (e.g., antibiotics for cancer) are examples. Nanoparticles’ performance is affected by their surface function and particle size. Additionally, drug release and particle degradation can differ from one system or another (e.g. ph sensitive biodegradable materials

Radiotherapy dose increaser
To increase tumor-specific doses, there has been much interest in gold and other particles containing heavy elements. The dose is selectively increased as the gold nanoparticles absorb more from the tumor than the surrounding healthy tissue. Local deposition near the nanoparticles is responsible for the treatment’s biological efficacy. This process is similar to heavy ion treatment.

Toxic gas detection
Based on the AuNPs characteristics of gold nanoparticles, a simple and affordable method has been developed to detect H2S in the atmosphere. The formation of HS- occurs when H2S is dissolved in weakly acid buffer solution. This can stabilize AuNPs, and allow for naked detection of H2S toxic level.

What’s the Difference Between Colloidal Silver And Colloidal Gold
The widespread use of colloidal silver for treatment of a wide range conditions includes viral and bacterial infection, allergies, burns, skin conditions and even cancer.
Colloidal gold has been shown to improve memory and cognitive function as well as reduce stress and headaches.

Is Colloidal Gold Natural?
The gold nanoparticles are an all-natural substance, without any chemical additives.

Development History and Application of Colloidal Gold

Posted on by adminLeave a comment
Colloidal Gold development history It is possible to trace the origins of gold nanoparticles back to the 16th Century. nanogold emerged from the scientific community after Paracelsus invented “drinking golden” for mental disorders. Faraday studied Dalton’s theory and used gold chloride in 1857 to reduce the solution. He also discovered that adding electrolytes can make it turn from ruby to blue, then finally agglutinate, but adding gelatin could prevent the change. Edward et.al. from Chicago discovered that nanogold solutions could help patients recover and improve their health. Faulk combined rabbit anti-salmonella and nano-gold antiserum in immunogold staining, which was the first to use this combination. This technology led to nano-gold immunolabeling technology.

1.The detection of cancer can be done with gold nanoparticles

Science Daily reported that nanoparticles of gold can be used to detect early cancers. Injecting nanogold into a patient can make cancer cells stick to the body and reflect certain wavelengths of light. 2.Gold nanoparticles may be used in chemotherapy for cancer Both normal and immune cells can be damaged by conventional chemotherapy. Xinhuanet.com stated that gold nanoparticles could improve the effectiveness of chemotherapy as well as reduce side effects. The gold nanoparticles have a high absorption rate and can therefore be coated with chemotherapy drugs to be delivered directly to the cancer cells. You can heat nanogold that has been infrared heated to kill cancer cells. This means that chemotherapy using nanogold can be used to effectively kill cancer cells, without affecting normal cells. It is possible to make 3.Nanogold into an injectable These USES can be combined with nano-gold injections. Chinanews.com has reported that nano-gold can be used to balance the electrolyte level of the cells. It also improves the immunity. It is small and will reach the cells quickly because it’s easily absorbed by the body. You can use it to restore immune system, reduce inflammation and pain, nerve pain, brain function, and blood circulation. Rmcplant (aka. Advanced material by Rmcplant .
