Gold nanoparticlesThere has been growing focus on the potential to use gold nanoparticles as tools in the field of bionanotechnology because of their unique optical, electronic and molecular recognition properties. Gold nanoparticles are known to be fairly stable and are regarded as generally bio-compatible. However, some studies have reported that these nanoparticles could be toxic to some organisms, including bacteria. The mechanism by which gold nanoparticles may confer toxicity to E. coli cells remains to be fully understood.
