Nanoparticles

• Nanoparticles r 1-100nm in size and are used in medicine, cosmetics, and electronics
• As particles decrease in size their SA increases in relation to their volume
• Nanoparticles are:

  • good catalysts
  • good at delivering drugs right into cells
  • used in Artificial joints and gears
  • added to plastics in sports equipment
• Nanoparticles have antibacterial, viral and fungal properties. They can be added to polymer fibres used to make surgical masks and wound dressing
• They can be used in antiseptic x-rays, fridge lining, socks and deodrants
• Titanium dioxide nanoparticles r used in sun creams to absorb UV light. They give better skin coverage than traditional sun cream, and r transparent
• Titanium dioxide nanoparticles r used as a coating for self-cleaning glass
