Paragraph starter

The design of degradable hydrogels, as explored by Kharkar, Kiick, and Kloxin (2013), offers a valuable precedent for creating dynamic biomaterials. Their work demonstrates that by engineering the degradation characteristics of hydrogels, designers can achieve orthogonal control over the cellular microenvironment, influencing cell adhesion, proliferation, and differentiation. This principle is directly applicable to the development of advanced scaffolds for tissue engineering and targeted drug delivery systems, where controlled material breakdown is essential for therapeutic efficacy and integration.
