Abstract:

DNA hybrid hydrogels based on pure DNA hydrogels were prepared by selecting three different hybrid factors to encode and restructure pure DNA hydrogels successively. The microstructure, mechanical properties and biological toxicity of DNA hybrid hydrogels were characterized. The results showed that the bivariate coding factor (sodium alginate/agarose) DNA hybrid hydrogels could meet the double evaluation indexes of mechanical strength and biological safety effect, with excellent biological safety, and improved mechanical properties by three orders of magnitude. The result of this work provides a new idea for programming DNA hydrogels, which expands its application in biomedical field.

Key words: DNA hybrid hydrogel, Encoding type, Double evaluation index, Mechanical property, Biomedical application
