【 摘 要 】

Stable nanoparticles of poly (DL-lactide-co-glycolide) (PLGA) have been prepared, which is photosensitized with near-infrared chromophores doped into the particle. Laser-induced white-light emission is observed from aggregates of the dye-doped nanoparticles, which shows spatial interference of nonlinear optical processes as the underlying mechanism. The accompanied break-up of the aggregates is promising as a possible mechanism for laser-triggered release of drugs.
