Progress in application of photodynamic antibacterial technology for textiles

为研究光敏剂在纺织材料上负载的抗菌效果和其在纺织品改性中应用的可能性,通过文献调研的方式对光动力抗菌的研究背景、光敏剂的种类、抗菌纺织品的应用情况、光敏剂常用的负载形式进行归纳整理。研究表明:作为一种能高效杀菌的新型抗菌材料,光动力抗菌纺织品具有良好的发展前景;通过化学共价键合光敏剂的改进负载方法能够解决常见负载方式中出现的结合牢度差、重复利用性不佳等问题,进一步拓宽抗菌材料的研发途径;目前光敏剂对其光敏抗菌性能均未能做到精准调控,今后的研究应当通过控制光敏剂的种类及光敏剂浓度等因素实现对光敏抗菌性能的把控。

In order to study the antibacterial effect of photosensitizers loaded on textile materials and the possibility of its application for textile modifications,the research background of photodynamic antibacterial,types of photosensitizers,current applications of antibacterial textiles,and photosensitizers were systematically reviewed.The commonly used loading forms of the drug are examined,and the conclusions and future prospects are summarized.The review indicates that photodynamic antibacterial textiles are a new type of antibacterial material that can be effectively sterilized and has a good development prospect.The improved loading method through chemical covalent bonding of photosensitizers can solve the problems of poor binding fastness and poor reusability associated with the commonly used loading methods,and can further broaden the research and development path of antibacterial materials.At the same time,it is realized that the current photosensitizers have not been able to control accurately their photosensitizing antibacterial properties.Future research should control the photosensitive antibacterial properties by controlling the types of photosensitizers and the concentration of photosensitizers.
