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.
Why are some people concerned about the widespread use of nanoparticles?
Some people are concerned about the widespread use of nanoparticles because of potential health and environmental risks. Nanoparticles can be difficult to detect and may have unknown impacts on living organisms and ecosystems. There is also a lack of regulation and understanding of their long-term effects.
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.
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 aggregation of nanoparticles?
Aggrgation of nanoparticles is where they stick together. This is undesirable in nanoparticle solutions, we want each nanoparticle to remain seperate. To combat this differing amounts of salts can be added to stop agglomeration, sodium citrate is one that is used for silver and gold nanoparticles. The zeta potential of the nanoparticle is a masure of its overall charge, ideally we want nanoparticles with a high positive or negative zeta potential as like charges repel each other and will stop nanoparticles from agglomerating.

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.
What does gold do in injected into your body?
Gold nanoparticles can be injected into people to check for tumors
Why are nanoparticles used in textiles?
because teh nanoparticles are so good
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.
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.

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?
Because they give us an advantage and we can make things that we probably thought wouldn't be possible before. Nanoparticles can be used to make cameras the size of a dust particle which can be used medically to check inside people and see what is going on for example. Nanoparticles also have many more purposes but there are some risks in using them and we aren't aware of all of them.
