Abstract
Black phosphorus quantum dots (BPQDs) were prepared by liquid stripping method, combined with a gel with reactive oxygen species (ROS) decomposition property, and wrapped onto TiO2 nanotube arrays loaded with ibuprofen (IBU) to construct a drug delivery system with near-infrared light (NIR) stimulation response. The generated ROS due to the presence of BPQDs can not only break the dynamic covalent bonds in the gel structure, leading to the decomposition of the gel, achieving NIR-responsive release of IBU and accelerating the release rate of IBU, but at the same time, ROS can play an obvious antibacterial role.
