Abstract
Fibroin and sericin are natural proteins obtained from cocoon and one of the spotlight materials for medical device. Medical device made of these proteins also has the advantage that this material is biodegradable in to amino acid. In this study, we prepared silk sponges using fibroin, sericin and additives. The characterizations of the silk sponges such as morphology, stability, and blood absorbency were observed. The structural stability of the silk sponge decreased significantly by increasing sericin contents. The effect on the concentrations of ethanol to induce crystallization was observed to be superior to 70% ethanol. Structural stability of silk sponges containing additives was very lower than those not containing additives. The blood absorbency of the silk sponges was found to be excellent, regardless of the composition of sericin and fibroin. The resilient power of these sponges was also very good, in spite of the repeated soaking and drying. Therefore, we expect that the silk sponges can be used medical supplies such as plastic implants and hemostatic cotton.
