Who found nanoparticles?
Michael Faraday is generally considered to be the first person to conduct scientific research on nanoparticles.
What is the effect of silver nanoparticles in plastic?
Silver nanoparticles are antibacterial, and when embedded in plastics for use in the medical field, are non-toxic. This makes silver nanoparticles useful in plastic applications such as surgical catheters.
Do nanoparticles have colors?
We cant really see nanoparticles to tell if they have colours, some do depending on what they are made from, but more commonly we see nanoparticles as a suspension in water, ethanol or some other solvent. These solutions can give rise to some intense colours, this is due to raylaigh scattering that takes place from the nanoparticles. A phemonon called surface plasmon resonance also has a part to play in the colours that we see for colloidal nanoparticles.
What is the role of surfactant in nanoparticle synthesis?
Surfactants are used in nanoparticle synthesis to control particle size, shape, and stability. They help in preventing agglomeration of nanoparticles by acting as a protective layer around them, and also facilitate the dispersion of nanoparticles in the reaction medium. Surfactants can influence the growth kinetics of nanoparticles and play a crucial role in determining the final properties of the synthesized nanoparticles.
What are the main concerns about nanoparticles?
The main concerns about nanoparticles relate to their potential adverse effects on human health and the environment. There is a concern that nanoparticles can penetrate cells and tissues, leading to inflammation or other toxic effects. Additionally, the long-term environmental impact of nanoparticles is not yet fully understood, and there is concern about their bioaccumulation in organisms and potential disruption of ecosystems.
What nanoparticles are in a swimsuit?
Some swimsuits are made with nanoparticles such as titanium dioxide or silver nanoparticles. Titanium dioxide nanoparticles can provide UV protection, while silver nanoparticles may help inhibit bacterial growth and odor.
How are nanoparticles constructed in to mascara's?
Nanoparticles are put into mascara\'s to reduce clumping. Nanoparticles are made out of the soot from a candle flame.
Why are nanoparticles used in textiles?
because teh nanoparticles are so good
Does green french clay contain nanoparticles?
Green French clay does not contain nanoparticles. French clay is naturally occurring and does not undergo processes that would create nanoparticles. It is typically in the form of fine powder and does not contain engineered nanoparticles.

What is a nanoparticles?
its is a nanoparticle of gold
Why are some people concerned about the use of nanoparticles?
Some people are concerned about nanoparticles because of potential health and environmental risks. Nanoparticles can be small enough to penetrate cells and tissues, potentially causing harmful effects. There are also concerns about the long-term impact of nanoparticles on the environment once they are released.
What is the purpose of nanoparticles?
to make milkshake

What are the advantages and disadvantages of nanobots?
Researchers in Finland and the US studied how certain nanoparticles interact with cells. Results indicated that nanoparticles may alter cell structure, causing the cells to die and also The team investigated cerium oxide nanoparticles and although no toxicity was found, changes in the function of the cell were noted after 30 minutes of exposure - such as a breakdown in communication between cells and possible DNA damage.
how does electrostatic forces prevents the nanoparticles to aggregate?
Electrostatic forces repel the nanoparticles from each other due to their like charges, preventing them from aggregating. This repulsion helps maintain the stability and dispersion of the nanoparticles in a solution by keeping them evenly distributed and separate.
