How small are Nanoparticles? | -Around 1-100 Nanometres. A Nanometre is 0.000,000,001 m.
-They have less than Thousands of Atoms, so they are bigger than Simple Molecules, but that's it really |
What do Fullerenes have, that can relate to Nanoparticles? | -They have Nanotubes, which is very Tiny Hollow Carbon Tubes
-These tubes are Strong, because of the Covalent Bonding Carbon does |
Nanoparticles have a high what to what? What does this result to? | -They have a high Surface Area to Volume Ration.
-This is because as Particles go down in Size, their Surface area Increases in relation with their Volume
-This results into them having Different Properties to Larger Particles, as a more Percentage of their Atoms can interact with the Substances and Environment more Freely |
Using Nanoparticles is known as ...? | Nanoscience |
What are some of the Nanoscience's that have been Created? | -They are Very Good Catalysts [From surface area: volume]
-Sun creams and Deodorants have been using Nanoscience. They do the Job and don't leave White Marks on the Skin
-Nanomedicine; Fullerenes are more easily Absorbed by the Body, so they can give the Right Drugs to the Needed Cells
-Lubricant Coating made via Fullerenes; they reduce Friction and can used in gears to artificial joints
-Nanotubes can conduct Electricity; use for minuscule electric circuits
-Nanoparticles added into Plastics in Sports Equipment, resulting in it being more Stronger and Durable, with no considerable mass change
-Silver Nanoparticles added to Polymer Fibres, used for Surgical Masks etc... Fibres gain Antibacterial Properties |
Do we fully understand what Nanoparticles can do to the Body? What does this lead to? | -We still don't know how they Affect the Body fully
-Nanoparticle Products are Tested a lot, to make sure the Risk is small
-People may be worried that the Products with Nanoparticles have been brought out Before the Harmful effects have been Found out. |
