  • Possible risks associated with the use of nanoparticles.
  • Nanoparticles behave differently from bulk materials, potentially causing unexpected side effects.
  • Lack of research on nanoparticles' risks could mean they are harmful to human health or the environment.
  • Nanoparticles could damage cells in the body.
  • Due to their small size, nanoparticles can be easily inhaled or absorbed through the skin, reaching cells.
  • They may be toxic to cells or catalyze harmful reactions, leading to cell damage.
  • Nanoparticles could harm the environment.
  • Silver nanoparticles have antibacterial properties, useful in wound dressings.
  • Improper disposal of nanoparticles can kill useful bacteria, disrupting natural ecosystems.
