Abstract:The use of antibiotics has led to the development of antibiotic resistance in many bacteria, which poses a serious threat to human and animal health. New antimicrobial materials not only effectively inactivate antibiotic-resistant bacteria but also do not cause bacteria to develop resistance, thus serving as an effective solution to this problem. At present, a variety of new antimicrobial materials have been developed, such as natural antimicrobial compounds and photocatalytic antimicrobial materials, which have strong antimicrobial effects, low prices, low pollution, and high biocompatibility. Researchers have employed the latest technology to carry out in-depth research on their antimicrobial mechanisms. This review systematically introduces the latest research progress in new antimicrobial materials and their antimicrobial mechanisms and discusses the problems and development prospects in this field.
