Au Nanoparticles-Doped Polymer All-Optical Switches Based on Photothermal Effects

Structural and Optical Behavior of Cu Doped Au Nanoparticles Synthesized by Wet-Chemical Method

The nanoparticles of gold doped with various percentage of copper (Cu 10%, 25%, 75%) were synthesized by wet-chemical method at room temperature. Copper (II) sulfate and gold (III) chloride trihydride was taken as the metal precursor and ascorbic acid as a reducing agent and anhydride maleic as surfactant. The reaction is performed with high-speed stirring at room temperature under nitrogen atm...

Electroactive Polymer Nanoparticles Exhibiting Photothermal Properties.

A method for the synthesis of electroactive polymers is demonstrated, starting with the synthesis of extended conjugation monomers using a three-step process that finishes with Negishi coupling. Negishi coupling is a cross-coupling process in which a chemical precursor is first lithiated, followed by transmetallation with ZnCl2. The resultant organozinc compound can be coupled to a dibrominated...

Au nanoparticles for targeted photothermal destruction of influenza

Influenza is caused by influenza virus, which outbreaks yearly and causing three to five million illness and about five hundred thousand deaths [1]. The 1918 Spanish Flu killed more than fifty million people, about 5 percent of the total population at the time [2]. The common treatment for influenza is antivirals. However, evidences have shown that antiviral medication can lead to viral resista...
