Bacterial toxin neutralization enhanced phototherapy Biomimetic materials for prevention and control of pathogenic bacteria is a novel strategy using biomimetic materials (biomimetic materials) as nanocarrier to realize the effective clearance and prevention of pathogenic bacteria (pathogenic bacteria) by neutralization of toxin (bacterial toxins) secreted by bacteria and the effect of enhanced phototherapy (phototherapy). Biomimetic materials are artificial materials that mimic biological structure and function and are highly biocompatibility, stability, tunability and functionality, and can be used in drug delivery, photothermal therapy and photodynamic therapy. Bacterial toxins are proteins secreted by bacteria that can destroy host cells and are one of the main pathogenic factors of bacterial infection. Bacterial toxins and enhanced light treatment of biomimetic materials can use the adsorption capacity of bionic materials, the bacterial toxins removed from infection site, to reduce inflammation and tissue damage, and use the optical properties of biomimetic materials, under a specific wavelength of light irradiation produce high temperature or reactive oxygen, to kill residual bacteria, prevent recurrence of infection.
