Photothermal therapy (PTT) is a promising method to kill pathogenic bacteria. However, using single-modal PTT, it is easy to cause tissue damage because of the overtemperature. Hence, it is necessary to combine PTT with other antibacterial strategies. In this study, we employed silver nanoparticles (Ag NPs) and mesoporous polydopamine (MPDA) nanoparticles to establish a multimodal antibacterial platform (MPDA@Ag). MPDA nanoparticles not only served as a photothermal transduction agent to convert light-energy to heat under the irradiation of nea...
