on a small scale in the lab there are many different ways. Most scientists have to do a search in existing litrature to find a way of making nanoparticles similar to what they want and then conduct systamatic experiments from there to see how changing paramaters will change the size and shape of the particles, with the goal of developing their own synthesis.
Two common reactions you will hear of to make nanoparticles are the Stober reaction, which uses tetraethylortho silicate, ammonium hydroxide, water and differing alcohols to make silica particles, these particles are used to make artificial opals, which in turn are used to study properties of light and its interaction of matter.
Another common one is the Lee and Miesel method of making silver or gold nanoparticles, this makes use of a metal salt and a solution of sodium citrate to reduce the salt to pure metal.

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
How are nanoparticles useful in producing industrial catalysts?
Can you recognize Cu nanoparticles without TEM microscopy?
Are nanoparticles the same as ordanary particles?
no they are not. nanoparticles are much smaller than normal/ordinary particles
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.
What is a nanoparticles?
its is a nanoparticle of gold
Where can you find nanoparticles?
asda
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 purpose of nanoparticles?
to make milkshake
How do you functionalize copper nanoparticles?
Thiols
What is the difference between nanoparticles and nanotechnology?
nanoparticles are basicly microscopic particles. Nanotechnology is the technology used to manipulate these nonoparticles for human use.
