合成化学,2022% 30(4), 280 -287 hXp:/// in aqueous solution due to its amphiphilic nature, and its Ouorescence quenching is as high as 92% - However, the Ouorescence graduVly recovers as the nanoparticlas reaches the tumor site because the d/ul/da bond / broken by the high concentration of glutathione ( GSH) in the tumor microenvironment,Ongly achieving a 16 fold increxsement of Ouorescence intensity. Therefore,there is an excellent potential of hph-resolution imaging of tumor tissue flr the dicyanina dye.
