Abstract
Biocompatible cross-linked materials, suitable for use in implants, wound dressings, and blood substitutes, are described. The materials are prepared by cross-linking biological substances, such as collagen, chitosan, or hemoglobin, with genipin, a naturally occurring cross-linking agent. The cross-linking agent has much lower toxicity than conventionally used reagents, and the cross-linked products have good thermal and mechanical stability as well as biocompatibility.
