This invention provides an antibacterial agent, its preparation method, and its application. The antibacterial agent comprises acyl-modified chitosan hollow microspheres and nano-antibacterial particles loaded on the surface of the modified chitosan hollow microspheres. This application exhibits excellent antibacterial effects. When used as a food packaging bag, it enables the nano-antibacterial particles to diffuse over a long period, thereby providing better antibacterial protection to the core of the food, rather than being limited to the surface.
