Applications of Hydrogels in Biomedicine

This is a general introduction to hydrogels which have a wide range of applications in biomedical engineering due to their complex structure. This paper reviews the development history of hydrogels and biomedical engineering in the past. It is analyzed that modern hydrogels are improved on the basis of traditional hydrogels using modern science and technology. For example, hydrogels with self-healing functions based on dynamic reversible chemical bonds can repair wounds, reduce infection rates in clinical medicine, and have a sterilization effect. Not only that, because of its good sterilization effect, hydrogels can also be used as materials for culturing cells in bioengineering. Analysis shows that the functions of hydrogels not only show diversification but also show combinations of a variety of functional groups because of their complex structure Various application fields also pointed out the limitations of current hydrogels and discussed the direction of development in the future.
