Preparation of Flexible Silk Fibroin Films Plasticized with Glucose

The preparation of regenerated silk fibroin microspheres

The objective of the present study is to investigate the possibility of preparing pure protein microspheres from regenerated silk fibroin (RSF). It is found that RSF microspheres, with predictable and controllable sizes ranging from 0.2 to 1.5 mm, can be prepared via mild selfassembling of silk fibroin molecular chains. The merits of this novel method include a rather simple production apparatu...

Rapid nanoimprinting of silk fibroin films for biophotonic applications.

With soft microand nanopatterned materials becoming increasingly useful for various optical, mechanical, electronic, microfluidic, and optofluidic devices, the extension of this paradigm to a pure protein-based material substrate would provide entirely new options for such devices. Silk fibroin is an appealing biopolymer for forming such devices because of its optical properties, mechanical pro...

Mechanical Properties of Robust Ultrathin Silk Fibroin Films *

Biocompatible materials have received increased interest due to their combination of unique physical, chemical, and biological properties and their potential in the fields of drug delivery, medical treatments, and other biological applications. Among the natural polymers, silkworm silk fibroin has been of interest for its use in textiles but also in consumer products such as cosmetic creams, lo...

Reaction of Silk Fibroin with Diazomethane

The treatment of silk with an ethereal solution of diazometbane result ed in a rapid decrease in tyrosine content, with no appreciable d ecrease in tensile strength <o f the fibers . The results indicate that the hydroxyl groups of tyrosine in the 'Untreated fibers are free. The total methoxyl content after treatment of the fiber for 25 hours or longer was greater than could be accounted for by...
