主 题:molecular assembly photosensitizers bioavailability improved therapeutic effect photodynamic therapy
摘 要:Photodynamic therapy(PDT)has emerged as an efficient method for cancer ***,traditional photosensitizers(PSs)always have low *** example,hydrophobic PSs tend to aggregate in cells and lead to aggregation-induced quenching;while hydrophilic PSs that have good solubility in water systems can hardly penetrate into cells whose membranes are *** overcome these drawbacks,suitable PSs that meet the requirements of PDT are *** investigations have been introduced,especially the molecular-assembly technique that can increase the bioavailability of PSs during the tumor therapy ***,increasing the quantum yield of reactive oxygen species(ROS)by adjusting the PS triplet state lifetime as well as developing aggregation-induced emission(AIE)agents can also improve the PDT *** review summarizes the molecular-assembly technique to obtain intelligent PSs to achieve high PDT ***,increasing the quantum yield of ROS by decreasing the energy gap between S_(1)and T_(1)states or increasing the spin–orbit coupling Hamiltonian are ***,we present the bioavailability of traditional PSs by improving the amphiphilicity of the PSs or using intelligent ***,the AIE PSs that can form ROS in the aggregated state under irradiation are ***,the perspective and challenges of PDT are discussed.
