A novel inexpensive method for preparation of silk nanofibers from cocoons

This study introduces a novel method for the production of silk nano-fibers via employing a mechanical and straightforward alternative to other toxic and costly chemical approaches. For this purpose, silk nano-fibers were separated from the cocoon using mechanical homogenizer and probe ultrasound. After the preparation of silk nanofibers, the product was characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy. The results were then evaluated in comparison with previous techniques and the advantages of the proposed method were investigated.
