Functional Microgels for the Decoration of Biointerfaces

Abstract Microgels constitute a class of materials that have increasingly proven interesting for utilization in biological applications. Due to the versatility provided by microgel constructs with regards to their dimensions, functionality and mechanical properties, their use as building blocks at biological interfaces has been a field of great interest for numerous researchers. In this review, we summarize the advantages that microgel‐based systems provide, when employed for the decoration of biointerfaces. These include control over the chemical structure, crosslink density and thickness of coatings fabricated using microgels. We also review the current state of affairs in the design of microgel‐laden biointerfaces and the challenges that remain unmitigated. Lastly, we provide some examples of current and future work being undertaken and developed with the goal of resolution of some of these issues.
