Degradation of protein in nanoplasma generated around gold nanoparticles in solution by laser irradiation

Article Abstract:

Lysozyme degradation by nanoplasma made of laser irradiation of gold nanoparticles in an aqueous solution containing lysozyme and gold nanoparticles is discussed. It is seen that the lysozyme degradation could be performed in a selective manner by changing the distance between a lysozyme molecule and a gold nanoparticle by controlling the affinity between them.

Dissociation and aggregation of gold nanoparticles under laser irradiation

Article Abstract:

Gold nanoparticles having an average diameter of ~8 nm are prepared in an aqueous solution of sodium dodecyl sulfate and are irradiated by a laser at 532 nm for size-reduction of the gold nanoparticles produced by laser ablation. It is shown that aggregation of the nanoparticles is not negligible when the laser fluence is high.

Surface properties of surfactant-free oil droplets dispersed in water studied by confocal fluorescence microscopy

Article Abstract:

The fluorescence spectrum of dye molecules, 4-(dicyanomethylene)-2-methyl-6- (p-dimethylaminostyryl)-4H-pyron (DCM), dissolved in water is measured. The conclusion states that DCM molecules are located in a polar surface region of n-decane and the polarity increases with decreasing the droplet diameter.
