Potential directions for future research of albumin-based hydrogels. There are mainly four potential research directions. Firstly, the activity of drugs, especially biomolecules, such as growth factors, protein inhibitors, etc., should be retained to the maximum extent during the preparation of albumin-based hydrogels. Second, other solutions need to be found to minimize the cost of producing albumin and even preparing albumin-based hydrogels. Such as development of recombinant HSA, enhancing the utilization of ovalbumin, etc. Third, various sizes of albumin-based hydrogels should be developed to meet the needs of clinical applications. The last, the translation of research on albumin-based hydrogels to clinical applications is still rare, and how to make more albumin-hydrogels research translate into practical applications which is one key question that we have to face.
