Silver Nanoparticles Pose Toxic Risk to Human Health

Rapid growth in the production and application of nanoparticles, such as silver nanoparticles, has increased human exposure and potential health risks. These tiny particles, used in a wide range of commercial products, have been shown to be toxic to mammalian cells and can cause damage to genes, cell membranes, and mitochondria. Research has demonstrated that silver nanoparticles can be absorbed into the bloodstream and cause toxicity in various organs, including the brain.

Key Takeaways:

  • Silver nanoparticles are widely used in various commercial products, including electronics, bio-sensing, clothing, food industry, paints, sunscreens, cosmetics, and medical devices.
  • Exposure to silver nanoparticles has been shown to cause toxicity in mammalian cells derived from skin, liver, lung, brain, vascular system, and reproductive organs.
  • Studies have demonstrated that silver nanoparticles can induce genes associated with cell cycle progression, DNA damage, and apoptosis in human cells at non-cytotoxic doses.
  • In vivo bio-distribution and toxicity studies in rats and mice have shown that silver nanoparticles administered through inhalation, ingestion, or intra-peritoneal injection were detected in the blood and caused toxicity in various organs, including the brain.
  • The mechanisms of silver nanoparticle-induced toxicity include effects on cell membranes, mitochondria, and genetic material.
  • Research suggests that silver nanoparticles can cause developmental and structural malformations in non-mammalian model organisms.
  • The potential health risks associated with silver nanoparticles demand further research and critical assessment.
