Liu X., Dai Q., Coutts J., Austin L., Knowles G., Huo Q., University of Central Florida, US

Gold nanoparticles and colloids have been used for a long time in biomolecular imaging and detection. With further understanding on many of the electrical and optical properties of gold nanoparticles revealed recently, the application of [...]

Synthesis of Dextran-Coated Nanoceria with pH-dependent Antioxidant Properties

Perez J.M., Asati A., Nath S., Kaittanis C., University of Central Florida, US

Cerium oxide nanoparticles (nanoceria) are potent free radical scavengers with neuroprotective, radioprotective, and anti-inflammatory properties. However, most synthetic procedures for nanoceria results in nanoparticles with poor water solubility or synthesized by procedures involving toxic solvents, [...]

Electric Field Assisted Assembly of Perpendicular Oriented ZnO Nanorods on Si Substrate
