Abstract
Inspired by the natural antimicrobial peptides, we have developed a benign antimicrobial nanodot (BAM dot) via a simple one-step hydrothermal synthesis. The BAM dot possesses the unique properties of both nanoparticles and biomaterials, leading to excellent antibacterial properties with a high therapeutic index. Specifically, this BAM dot has ultrasmall size (3.83 ± 0.73 nm) with a charged neutral surface. They also exhibited amphiphilic and zwitterionic-like properties, which enabled effective bacteria membrane permeabilization, leading to a rapid bactericidal effect and significant biofilm removal. This study opens up new opportunities to design effective bioinspired nanomaterials for combating superbugs against drug resistance and their related applications.
