1POD Nanozyme optimized by charge separation engineering for light/pH activated bacteria catalytic/photodynamic therapy显示文摘The current feasibility of nanocatalysts in clinical anti-infection therapy,especially for drug-resistant bacteria infection is extremely restrained because of the insufficient reactive oxygen generation.Herein,a novel Ag/Bi2MoO6(Ag/BMO)nanozyme optimized by charge separation engineering with photoactivated sustainable peroxidase-mimicking activities and NIR-II photodynamic performance was synthesized by solvothermal reaction and photoreduction.The Ag/BMO nanozyme held satisfactory bactericidal performance against methicillin-resistant Staphylococcus aureus(MRSA)(~99.9%).The excellent antibacterial performance of Ag/BMO NPs was ascribed to the corporation of peroxidase-like activity,NIR-II photodynamic behavior,and acidity-enhanced release of Ag^(+).As revealed by theoretical calculations,the introduction of Ag to BMO made it easier to separate photo-triggered electronhole pairs for ROS production.And the conduction and valence band potentials of Ag/BMO NPs were favorable for the reduction of O_(2) to·O_(2)^(−).Under 1064 nm laser irradiation,the electron transfer to BMO was beneficial to the reversible change of Mo^(5+)/Mo^(6+),further improving the peroxidase-like catalytic activity and NIR-II photodynamic performance based on the Russell mechanism.In vivo,the Ag/BMO NPs exhibited promising therapeutic effects towards MRSA-infected wounds.This study enriches the nanozyme research and proves that nanozymes can be rationally optimized by charge separation engineering strategy.Changyu Cao Tingbo Zhang Nan Yang Xianghong Niu Zhaobo Zhou Jinlan Wang Dongliang Yang Peng Chen Liping Zhong Xiaochen Dong Yongxiang Zhao 2022Signal Transduction and Targeted Therapy2022,7,4:1

3Efficient charge transfer in WS_(2)/W_(x)Mo_(1-x)S_(2) heterostructure empowered by energy level hybridization显示文摘Photoinduced charge transfer(CT) is decisive to the efficiency and speed of photoelectric conversion in two-dimensional(2D) van der Waals(vd Ws) heterostructures. Generally, CT rate enhancement is realized by increasing the band offset(BO). In this study, we propose that a fast and efficient CT can be realized via strong hybridization of energy levels in 2D vd Ws heterostructures with minimal BO. Firstprinciples calculations reveal that the smallest energy difference between conduction-band edges and minimal BO in the WS_(2)/W_(x)Mo_(1-x)S_(2)(x = 0.78) heterostructure yields the strong hybridization of energy levels and then results in ultrafast CT(2.7 ps). Experimental results agree with theoretical calculations. The photoluminescence of WS_(2) is quenched in the WS_(2)/W_(x)Mo_(1-x)S_(2)(x = 0.78) heterostructure, attributable to the strong hybridization-induced fast and efficient CT. This study provides insights into the mechanism of CT in heterostructures and offers new strategies to create superior optoelectronic devices with fast and efficient photoelectric conversion.Xuhong AN Yehui ZHANG Yuanfang YU Weiwei ZHAO Yutian YANG Xianghong NIU Xuan LUO Junpeng LU Jinlan WANG Zhenhua NI 2023Science China(Information Sciences)2023,66,2:0
