Abstract
The present invention is directed to copolypeptide hydrogels (DCH) containing non-ionic hydrophilic residues (DCHEO), incorporation of thermoresponsive elements into DCHEO, to generate thermoresponsive DCH (DCHT), and hydrogels that include a combination of DCHEO and DCHT. The invention includes preparation, uses, compositions containing the hydrogels and methods of tuning the hydrogels. The hydrogels can be used to deliver an agent or cells to an organism.
