Nanoscience Flashcards
How do you find the surface area to volume ratio?
surface area/ volume
What happens to particles SA when they decrease in size?
Their SA increases in relation to their volume
What are nanoparticles SA:Vol like?
High
What is an advantage of using nanoparticles?
You don’t need as much to work as an effective catalyst compared to material made of normal sized particles
Where are nanoparticles used?
Electric circuits
Used to deliver drugs (Buckminster fullerene)
Cosmetics
Where is silver nanoparticles used?
In things like surgical masks and wound dressings as they contain antibacterial properties
Why are nanoparticles found in sun cream?
Good protectors of UV rays and also give better skin coverage
Why are people wary about nanoparticles?
As they are worried they may harm our bodies but yet we do not know the long term impacts
