摘要:木质素是一种生物基材料，具有酚羟基、醇羟基、羰基和羧基等官能团，深入了解木质素的特性和结构将有助于木质素高值高质的开发利用。考虑到木质素在生产增值产品方面的多功能特性（如木质素具有抗氧化、抗菌、抗病毒、生物相容性好、无毒等特性），本文主要综述了木质素基复合材料在抗菌载体、生物分解、药物传递、抗紫外线和组织工程等领域的潜在应用，以及木质素纳米粒子与碳材料在生物医学中的巨大作用。

Abstract:Lignin is a bio-based material with functional groups such as phenolic hydroxyl， alcohol hydroxyl， carbonyl and carboxyl groups. An in-depth understanding of the properties and structure of lignin will facilitate the high-value and high-quality exploitation of lignin. Considering the versatile properties of lignin in the production of value-added products （e.g.， lignin is of antioxidant， antibacterial， antiviral， biocompatatible and non-toxic properties）， this study mainly reviewed the potential applications of lignin-based functional composite materials in areas of antibacterial carriers， biodegradation， drug delivery， UV resistance and tissue engineering，etc. as well as the great role of lignin nanoparticles and carbon materials in biomedicine.
