Nanoparticles

• Nanoparticles

  Small particles with a diameter of between 1 and 100nm
• Nanoscience

  Field of research that focuses on nano particles.
• Why do nanoparticles have a high surface area to volume ratio

  They are very tiny
• 4 uses of nanoparticles

  Catalysts

  Deliver medicines

  Circuits

  Wound dressings and surgical masks
• Why do nanoparticles make good catalysts

  Have high surface area to volume ratio so only small amount of the material is needed to have a large effect
• How could spherical fullerenes be used in medicine

  They help deliver drugs around the body
• Why are silver nanoparticles often infused into wound dressings and masks

  They have anti bacterial properties
• Why do some people oppose using nanoparticles

  We don’t fully understand how they work and may have negative effects on the body
