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.


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.

How do you get nanoparticles off your hands coz they are stuck?

Wear gloves while working in the nanotechnology lab. Any natural nanoparticles such as dust will not harm your hand, but you can get some off using soap and water.


Some people are concerned that genetically engineered crop plants would?

Take over the world and enslave humankind. And some people are concerned that the events of September 11, 2001 were a US government conspiracy. And some people are concerned that UFO's are real and the government is trying to hide it. Come on, people, get a grip on reality.

Are nanoparticles the same as ordanary particles?

no they are not. nanoparticles are much smaller than normal/ordinary particles


What do nanoparticles do in mascara?

Get people to pay more. It's just a marketing gimmick."Nanoparticles" means, basically, "really really small bits." So a company advertising that their mascara has "nanoparticles" is really just saying "we powdered up the black stuff in our mascara really fine, so you won't have clumps of it the size of peas hanging off your eyelashes." While I suppose this is better than the alternative, the nanoparticles really don't do much of anything, other than (presumably) not form clumps large enough to be seen.(Soot, from a candle flame? That's pretty much ALL nanoparticles. So it's not like this is some exotic space-age material.)


Why are nanoparticles used?

Nanoparticles are used for various purposes due to their unique properties at the nanoscale. They offer a large surface area to volume ratio, which makes them useful for catalysis, drug delivery, and sensing applications. Additionally, nanoparticles exhibit quantum confinement effects, allowing for manipulation of their optical, electronic, and magnetic properties.


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.
