Developing antimicrobial therapies not rely on antibiotics is an expective way to resolve the threat of drug-resistant bacteria, such as photodynamic antimicrobial therapy (APDT). However, the main antibacterial species in APDT are reactive oxygen species (ROS), and the overproduction of ROS will cause serious inflammatory and delay wound healing. Therefore, it is necessary to solve this contradiction in order to realize anti-inflammatory in the process of APDT. Here, we selected Ce6 as a photosensitizer for APDT, phenylboronic acid (PBA) was introduced on Ce6 (as Ce6-D-P) to get bacterial targeting, and then covalently grafted curcumin (Cur) on Ce6-D-P (as Ce6-D-P-C) to obtain anti-inflammatory ability. Finally, antibacterial poly(β-amino ester)(PBAE) was used as carrier to load Ce6-D-P-C to form nanoparticles Ce6-D-P-C@PBAE. Under light irradiation, ROS can be produced for APDT, and also, boroester bond on Ce6-D-P-C will broke to release small Cur molecules, and then released from Ce6-D-P-C@PBAE to perform anti-inflammatory. As a result, after ROS treatment, anti-inflammatory was achieved, forming stepwise antibacterial and anti-inflammatory therapy. The study showed that Ce6-D-P-C@PBAE was biosafe with good cell activity and also no hemolysis. The drug loading content of Cur in Ce6-D-P-C@PBAE can reach 11.2 %. When Ce6-D-P-C@PBAE was stimulated by light, the responsive release of Cur will achieve. In vivo studies, Ce6-D-P-C@PBEA can collaboratively kill bacteria and regulate inflammatory responses, as well as inhibiting and eliminating local inflammation, thereby promoting the healing of infected wounds. As a result, the Ce6-D-P-C@PBAE nanoparticles had both antibacterial and anti-inflammatory therapy abilities, which was important for combating bacterial infections and promoting wound healing.
