Embodiment 1
[0017] Example 1: 5% hyaluronan solution was reacted with dopamine to obtain dopamine-modified hyaluronan with a dopamine content of 15%. The purified product was formulated into a 5% aqueous solution and mixed with genipin and ferric chloride And waterproof lamp bead particle type LED light strip blended for a period of time, obtained from healing medical gel. The addition ratio of genipin to the system is 0.5%, and the addition ratio of ferric chloride is 0.2%.
Embodiment 2
[0018] Embodiment 2: 10% polylysine solution reacts with dopamine to obtain dopamine-modified polylysine, the content of dopamine is 25%, the product after purification is formulated into 10% aqueous solution, and with sebacic acid disuccinimide Ester and Ferric Chloride and Waterproof Lamp Beads Granular LED Strips are blended for a period of time to obtain healing medical gel. The addition ratio of disuccinimide sebacate to the system is 1.2%, and the addition ratio of ferric chloride is 0.5%.
Embodiment 3
[0019] Example 3: Chitosan and collagen are blended and dissolved to make an aqueous solution and react with dopamine to obtain a dopamine-modified proteoglycan mixed solution, wherein the content of chitosan is 2%, the content of collagen is 9%, and the content of dopamine is 12%. , the purified product is formulated into a 10% aqueous solution, and blended with four-arm polyethylene glycol succinimide glutarate, ferric chloride and a waterproof semiconductor solid-state cold light source LED sheet for a period of time, obtained from Healing Medical gel. The addition ratio of four-arm polyethylene glycol succinimide glutarate in the system is 0.8%, and the addition ratio of ferric chloride is 0.5%.
