Silver nanoparticles are ubiquitous in today’s commercial marketplace. Despite decades of research, there is still disagreement about the risk that silver nanoparticles pose to human and environmental health. There is often a lack of correlation between measured physical properties and the measured biological endpoints, making it difficult to establish trends, and discrepancies between different cell...
Commercially available 10- to 60-nm silver nanoparticles with different surface functional groups were tested for biological activity in different cell lines. Particle uptake and stability were examined in cell culture media to determine the correlation between particle stability, uptake, and cytotoxicity. Trends in rising toxicity with decreasing particle diameter were observed; however, correlations...
