Nanoparticles-New medical potential-Today and tomorrow

This is the latest version of this item.

Abstract

Thoroughly analyzing scientific achievements, exploring divergent features of gold nanoparticles, it was obviated that gold nanoparticles are considered as risky for human health. Experiments have shown that gold nanoparticles can result in uptake via the relevant exposure routes. The gold nanoparticles and the cell types used for their exposure are likely to influence the uptake, sub-cellular distribution, and toxicity of gold nanoparticles. However, investigations of metal particulates are still in their infancy at this time, and have concentrated on revealing the toxicity, safety, tissue distribution, antibacterial properties and cellular uptake of gold nanoparticles. Consequently, more comprehensive studies are required to more fully understand the toxicity versus safety associated with metal particulate exposure. Inevitably, any emerging technology requires extensive safety assessment before coming to market, including diagnostics, medications and cosmetics. While comparing and evaluating newly established properties at nanoscale, consumers may experience confusion concerning safety issues. In the recent years responsibilities for the control and regulatory mechanisms increased to guard the utilization of nano-particles into cosmetic products.
