AldehydeAmine Chemistry Enables Tissue Adhesive Materials to Respond to Physiologic Variation and Pathologic States

AbstractBiomaterials science represents the next frontier in medical therapeutics. Innovations in materials design and formulation have helped create previously unimaginable interventions and composite devices with materials whose structure and function evolve with time. Yet, materials development has outstripped our ability to explain why, when, and how these materials work. Current characterization means are limited, especially for dynamic erodible materials that are specifically designed to fade away. This complexity and dynamism of emerging materials and the impact they have on tissue make it challenging to understand and predict material interactions with local tissues. Because tissuebiomaterials interactions are determined not only by the innate properties of the materials, but also by the local microenvironment at the implantation site, we must now examine the impact of target tissue site, state, and incidence of a disease on material performance, efficacy, and biocompatibility. This issue becomes increasingly important when considering surface interacting materials, whose intimate interactions with tissues are dictated by local mechanical forces, tissue target site, and th
