Effect of nucleants in photothermally assisted crystallization

Photochemical & Photobiological Sciences, 2017
Laser-induced crystallization is emerging as a promising technique to crystallize biomolecules like amino acids and proteins. The use of external materials as nucleants and novel seeding methods open new paths for protein crystallization. We report here the results of experiments that explore the effect of nucleants on laser-based crystallization of ...

Unique Photothermal Response and Sustained Photothermal Effect of pH‐Responsive Gold‐Nanoparticle Aggregates

ChemPhysChem, 2012
Hot gold: The photothermal response upon pulsed laser irradiation is studied for pH-responsive gold-nanoparticle aggregates and compared to that of gold nanorods. The aggregates show a slight red shift in the absorption spectrum and retain the photothermal effect, whereas the nanorods lose the photothermal effect and exhibit a stark blue shift in the ...

Temperature effect on photothermal lens phenomena in water: Photothermal defocusing and focusing

Chemical Physics Letters, 1989
Abstract Depending on whether the measurements are performed at temperatures lower or higher than −0.01°C, the photoinduced thermal lens in water can have either positive (converging) or negative (diverging) focal length. At precisely −0.01±0.04°C, no thermal lens signal could be observed.

Gigahertz photothermal effect in silicon waveguides

Applied Physics Letters, 2008
We present a theoretical and experimental study of the frequency response of the photothermal effect in silicon waveguides. The effect is studied for modulation frequencies up to 3GHz using integrated photonic circuits in Mach–Zehnder and ring oscillator configurations.
