Cross-polarization optical coherence tomography for early bladder-cancer detection: statistical study.

abstract：:Nanosecond pulsed laser irradiation can trigger a release of nucleic acids from gold nanoparticles, but the involved nanoeffects are not fully understood yet. Here we investigate the release of coumarin labeled siRNA from 15 to 30 nm gold particles after nanosecond pulsed laser irradiation. Temperatures in the particl...
