Metal‐based nanoparticles and their toxicity assessment

Antibacterial activity of gold nanoparticles and their toxicity assessment

Methods The present study involved the synthesis of gold nanoparticles using a sodium cholate, as both reducing and capping agent and characterization by UVVisible spectroscopy and High ResolutionTransmission Electron Microscopy (HRTEM). The antibacterial activity on significant bacterial species was evaluated by micro broth dilution method. The mechanism for antibacterial action of the gold na...

Nanoparticles: their potential toxicity, waste and environmental management.

This literature review discusses specific issues related to handling of waste containing nanomaterials. The aims are (1) to highlight problems related to uncontrolled release of nanoparticles to the environment through waste disposal, and (2) to introduce the topics of nanowaste and nanotoxicology to the waste management community. Many nanoparticles used by industry contain heavy metals, thus ...
