Abstract
Structure engineering is of great importance to enhance the carrier separation efficiency of multiphoton absorption (MPA) materials for near-infrared (NIR) light-driven reactive oxygen species (ROS) generation. In this study, the MPA-responsive potassium/cyano group-functionalized graphitic carbon nitride was investigated, demonstrating charge redistribution and improved carrier separation efficiency by density functional theory calculations and experimental results. With various types of boosted ROS generation under UV-vis or NIR-II light irradiation, the potassium/cyano group-functionalized graphitic carbon nitride could achieve efficient multiphoton photodynamic therapy after reducing the particle size. This study developed a simple strategy to manipulate charge distribution for booting NIR light-activated ROS generation in efficient multiphoton photodynamic therapy.
期刊介绍：
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
