摘要:

家蠶蠶絲是一種天然的蛋白質(zhì)纖維，蠶絲及其衍生物（凝膠、蠶絲薄膜和海綿等）具有獨特的力學(xué)性能，良好的生物相容性和生物降解性，已經(jīng)被應(yīng)用在紡織、生物醫(yī)學(xué)等領(lǐng)域。最近，利用蠶絲獨特的性質(zhì)制備光學(xué)功能化蠶絲的研究吸引了研究者的興趣。本文基于對蠶絲的絲膠和絲素結(jié)構(gòu)組成的總結(jié)，介紹目前對蠶絲結(jié)構(gòu)的相關(guān)研究進(jìn)展，綜述了近年來對光學(xué)功能化蠶絲的研究，具體包括光學(xué)功能絲的重要種類、制備和應(yīng)用。重點介紹了熒光性功能蠶絲通過基因工程、喂食法和復(fù)合等制備方法，該種材料用于生物支架成像、藥物緩釋載體和光學(xué)器件等領(lǐng)域。本文還總結(jié)了利用生物仿生技術(shù)制備具有光子晶體結(jié)構(gòu)色蠶絲材料，這為化妝品，變色服飾和生物光控器件開辟了新方向；此外，蠶絲材料還可以應(yīng)用于非線性光學(xué)領(lǐng)域，如光限幅和激光防護(hù)。

Abstract:

As a kind of nature protein fiber, 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 industry and biomedical. Recently, there is a growing interest to introduce 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 highlights 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, it’s reported the fabrication of silk fabrics with photonic crystals structure colors using biomimetic techniques, which opened up a new direction of cometic, color dress, various devices and biological optical devices. At last, silk materials also can be applied in nonlinear optics, such as optical limiting and laser protection.
