They may be toxic to cells.
Nanoparticles are put into mascara\'s to reduce clumping. Nanoparticles are made out of the soot from a candle flame.
because teh nanoparticles are so good
ice cream melts in the sun because when the heat of the sun get to the ice cream its starts to melt like ice.
Sun cream absorbs or reflecting some of the UV rays from the sun to protect against sun burn.
The ice cream melts in the sun because it is supposed to be frozen but when the sun hits ice cream it takes the ice off of ice cream so it is not frozen.
If you put the ice cream out in the sun, it will melt down.
Can you recognize Cu nanoparticles without TEM microscopy?
no they are not. nanoparticles are much smaller than normal/ordinary particles
The cream/lotion you are talking about is sun block.
Michael Faraday is generally considered to be the first person to conduct scientific research on nanoparticles.
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.
