Natural and synthetic melanins are promising pigments for several uses, such as biosorbents and bioadhesives. Further, their high biocompatibilities and excellent biological activities potentially allow them to be ideal biomaterials for environmental and biotechnological applications. Naturally occurring melanin has been used as a biosorbent for the environmental treatment of organic chemicals and for metal ion removal, and melanins have been chemically engineered to function more efficiently. In addition, melanin has been engineered for use as an adhesive coating material, and its polymeric properties have been enhanced for medical applications. Clearly, given melanin’s high biocompatibility and biodegradability, it is a very viable biopolymer for further applications in environmental biotechnology fields. In this review, we highlight the uses of melanin as a biosorbent and bioadhesive in biotechnology fields.

天然和合成的黑色素是有前途的颜料，可用于多种用途，例如生物吸附剂和生物粘合剂。此外，它们的高生物相容性和出色的生物活性可能使它们成为用于环境和生物技术应用的理想生物材料。天然存在的黑色素已被用作生物吸附剂，用于有机化学物质的环境处理和金属离子的去除，并且黑色素已经过化学工程改造以更有效地发挥作用。此外，黑色素已被设计用作粘合剂涂料，并且其聚合性能已增强，可用于医疗应用。显然，由于黑色素具有高度的生物相容性和生物降解性，因此它是一种非常可行的生物聚合物，可进一步用于环境生物技术领域。在这篇评论中
