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.
