Lignin is a versatile biomass that possesses many different desirable properties such as antioxidant, antibacterial, anti-UV, and good biocompatibility. Natural lignin can be processed through several chemical processes. The processed lignin can be modified into functionalized lignin through chemical modifications to develop and enhance biomaterials. Thus, lignin is one of the prime candidate for various biomaterial applications such as drug and gene delivery, biosensors, bioimaging, 3D printing, tissue engineering, and dietary supplement additive. This review presents the potential of developing and utilizing lignin in the outlook of new and sustainable biomaterials. Thereafter, we also discuss on the challenges and outlook of utilizing lignin as a biomaterial.

木质素是一种多功能生物质，具有许多不同的理想特性，例如抗氧化、抗菌、抗紫外线和良好的生物相容性。天然木质素可以通过多种化学过程进行加工。加工后的木质素可以通过化学修饰改性为功能化木质素，以开发和增强生物材料。因此，木质素是各种生物材料应用的主要候选材料之一，例如药物和基因传递、生物传感器、生物成像、3D 打印、组织工程和膳食补充剂添加剂。本综述介绍了在新型可持续生物材料前景中开发和利用木质素的潜力。此后，我们还讨论了利用木质素作为生物材料的挑战和前景。
