A novel flurophore-cyano-carboxylic-Ag microhybrid: Enhanced two photon absorption for two-photon photothermal therapy of HeLa cancer cells by targeting mitochondria

A novel two-photon photothermal therapy (TP-PTT) agent, based on an organic-silver microhybrid with SPR enhanced two-photon absorption characteristic, stained the mitochondria part of HeLa cells and exhibited excellent TP-PTT effect under two-photon laser irradiation at 780 nm.255
