摘　　要：Comprehensive Summary SPASER nanoparticle(NP),with small size,ultranarrow spectral-line and good biocompatibility,is a potential biomedical nanoprobe.However,owning to the striking light absorption capacity of Au-resonator,huge energy could accumulate under strong pumping-laser,which would lead to poor photo-stability and unexpected photo-damage to SPASER NP,and is harmful to its future practical application but hasn't been systematically studied in experiment.
