Abstract:

The various types of diseases caused by pathogenic bacteria pose a constant threat to human life and health. The drug resistance of pathogenic bacteria is gradually increasing, which leads to a gradual decrease in the effectiveness of antibiotics. However, most of the current nanomaterials are mainly single-component antibacterials, whose singularity and one-sidedness hinder the comprehensive prevention and efficient control of microbial contamination. In order to prevent and curb the growth and spread of bacterial resistance, this work proposed the strategy of effectively compounding multiple antibacterial materials and constructing a multifaceted antibacterial system to achieve a multi-component synergistic bactericidal effect. In the study, a novel Au NP@pAMPS-Cl-b-PEG nano-antibacterial material was successfully developed by combining N-halamine polymer, which is an efficient bactericidal polymer, with gold nanoparticles(Au NP) possessing photothermal effect(PTT). The antibacterial material aims to fully utilize the synergistic effect of photothermal and chemical antibacterial mechanisms to effectively inhibit bacteria and reduce the occurrence of antibiotic resistance. This research provides a new strategy for combined antibacterial therapy, which is of great theoretical significance and reference value for promoting the development and application of novel antibacterial drugs.
