摘要:纳米材料主要来源于化石原料，但由于化石原料的不可再生性，严重制约着纳米材料的进一步发展。生物质作为制备纳米材料的原料，具有来源丰富、绿色可再生的特点，其中木素是仅次于纤维素的自然界第二大可再生高分子聚合物，具有良好的生物亲和性。由木素制备的纳米粒子可替代部分有害的纳米材料广泛地应用在食品、生物医药、环境修复等领域，因此木素纳米粒子越来越受到人们的关注。本文对近年来木素纳米粒子的制备工艺及其在紫外防护、抗菌、药物运输等方面的研究进展进行了综述，旨在为木素高值化利用提供一定参考。

Abstract:Nanomaterials are mainly derived from inorganic or fossil materials. However， the non-renewability of inorganic or fossil materials seriously restrict the further development of nanomaterials. Biomass can be used as a source of nanomaterials. They are rich in content and green and renewable. Among them， lignin is the second largest renewable macromolecular material in nature， second only to cellulose， which has good biological compatibility. Therefore， nanoparticles prepared by lignin can be widely used in place of toxic nanomaterialsin the fields of human health， bio-medicine， and environmental remediation， and lignin nanoparticles have attracted more and more attention. This article reviews the methods used to prepare lignin nanoparticle and its application in UV protection， antibacterial， and drug transport， and aims to provide reference for people to study the high value applicationof lignin．
