Functionalization of Silkworm Silk Materials in Optics

Abstract

家蚕蚕丝是一种天然的蛋白质纤维,蚕丝及其衍生物(凝胶、蚕丝薄膜和海绵等)具有独特的力学性能、良好的生物相容性和生物降解性,已经被应用在纺织、生物医学等领域。最近,利用蚕丝独特的性质制备光学功能化蚕丝吸引了研究者的兴趣。基于对蚕丝的丝胶和丝素结构组成的总结,介绍了目前蚕丝结构的相关研究进展,综述了近年来对光学功能化蚕丝的研究,具体包括光学功能化蚕丝的重要种类、制备和应用。重点介绍了荧光性功能蚕丝基因工程、喂食法和复合等制备方法,该种材料用于生物支架成像、药物缓释载体和光学器件等领域。总结了利用生物仿生技术制备具有光子晶体结构色的蚕丝材料,这为化妆品,变色服饰和生物光控器件开辟了新方向;此外,蚕丝材料还可以应用于非线性光学领域,如光限幅和激光防护。As a kind of nature protein,silkworm silk and its derivatives( gels,silk fibroin foams and films) possess the unique mechanical properties,biocompatibility and biodegradability,which have been applied to textile and biomedical industry.Recently,there is a growing interest in introducing optical functionalities into silk.Based on the structure of sericin and fibroin,functionalization of silk was summarized in optics,specifically including the important species,preparation and application of fluorescent silk.This paper highlighted that the fluorescent silk can be produced by genetic engineering,feeding,and compositing etc.,which can be applied in scaffold imaging,drug delivery,and optical devices.In addition,this paper reviewed the fabrication of silk fabrics with photonic crystals structure colors using biomimetic techniques,which opens up a new direction of cometic,color dress,various devices and biological optical devices.At last,silk materials can also be applied in nonlinear optics,such as optical limiting and laser protection.厦门大学中组部千人计划项目配套经
