When irradiated with light, gold nanoparticles become hot quickly, hot enough to generate explosive microbubbles that will kill nearby cancer cells, a physical process known as the photothermal effect. To boost this approach, researchers at the University of California, Los Angeles, have developed a method for creating supramolecular assemblies of gold nanoparticles that function [...]

Recently, hybrid structures of microorganisms with inorganic nanoscale moieties have received great interest owing to their potential in fabricating electronic systems. The electronic properties of metal nanoparticles, as a result of the singleelectron transport of current,[1] make them ideal materials for nanodevices. Concomitantly, the nanostructure of microorganisms such as bacteria,[2] viruses,[3, 4] and yeast[5] are [...] The objective of this study was to develop a practical method to prepare a stable dispersion of TiO2 nanoparticles for biological studies. TiO2 (rutile/anatase) dispersions were prepared in distilled water following by treated with different ultrasound energies and various dispersion stabilizers.Journal of Nanoscience and Nanotechnology, 10(8): 5213-5219 (August 2010) |
