A single lactic acid molecule has one hydroxyl group and one carboxyl group. Among them, the -OH of one lactic acid molecule is dehydrated and condensed with -COOH of other molecules, and then its -COOH is dehydrated and condensed with -OH of other molecules. In this way, they A polymer is formed called polylactic acid. Polylactic acid, also known as polylactide, belongs to the polyester family. In addition to being biodegradable, products made of polylactic acid have good biocompatibility, gloss, transparency, hand feel and heat resistance. Polylactic acid (PLA) also has certain bacteria resistance, flame retardancy and UV resistance. Therefore, in the field of biomedicine, polylactic acid materials can be used as drug transport materials, tissue engineering scaffold materials, bone repair materials, etc.. The medical field is an early field of application of PLA and its compounds. At present, extensive basic research and clinical applications have been carried out in the fields of orthopedic surgery, thoracic surgery, maxillofacial surgery, and tumor targeted therapy. However, due to its own lack of luminescence properties, it is not conducive to drug tracking in vivo after administration as a drug carrier. Therefore, adding a fluorophore to PLA is a better solution for later research.
