A novel inexpensive method for preparation of silk nanofibers from cocoons

AbstractIn the present study , a novel method for the production of silk nano fibers are presented . In this way , a mechanical and easy technique is used instead of toxic and costly chemical methods . Also , the separation of silk nano fibers from the cocoon was carried out by mechanical homogenizer and probe ultrasonic homogenizer . After the preparation of silk nanofibers , the product was characterized by Fourier transform infrared spectroscopy (FT - IR) and scanning electron microscope (SEM) . The results were compared with previous techniques and the advantages of the new method were investigated.
