Study on Laser Processing Technology of Biohydrogel and Its Biocompatibility in Vitro
In order to solve the problem that the production of biohydrogel additives cannot achieve fine structure printing,the laser processing was used to experiment SA hydrogel and GelMA hydrogel.The mechanism of laser processing biohydrogel and the influence of parameters on the laser processing effect were explored through laser cutting,laser engraving and other experiments,and the growth of HUVECs cells on the laser processed hydrogel was analyzed through cell proliferation experiments.The experiment showed that the parameters such as laser power and feed speed have great impacts on the depth and surface quality of laser processed hydrogels,and HUVECs cells can proliferate normally on the processed hydrogels,which provides a useful guidance for biomedical applications.
