Swellable polyethylene glycol (PEG) amine:dextran aldehyde composite materials are now emerging as a controlled, biocompatible tissue adhesive. We explain how preservation of natural tissue amines provides biocompatibility for PEG:dextran that exceeds the stringent, destructive cyanide-based chemistry of cyanoacrylates, and adhere far better than fibrin glue. Strategic variations of material composition allow for the improvement of biocompatibility and adhesion strength. Material variations can be tailored to match the needs of specific tissue beds for an array of clinical applications. PEG:dextran cohesive properties are most responsive to variations in the PEG component (number of arms and solid content), while tissue-material adhesion strength are primarily determined by the number of aldehydes in the dextran. Adhesive biomaterials seal wounds, scaffold tissues, and deliver drugs, but adhesion often clashes with biocompatibility. Stringent nonspecific chemical binding optimizes the former, water-based systems the latter, but the two are at odds. We explain how composite materials that harness natural amine-aldehyde interactions for tissue adhesion and internal cohesion provide a novel set of biocompatible biomaterials with controlled adhesion.
