실크 피브로인의 겔화

The intermolecular hydrogen bond between silk fibroin in aqueous solution facilitates gelation of silk fibroin. The dependence of gelation by the concentration of silk fibroin, pH and temperature was investigated. The gelation time of silk fibroin is decreased with increasing the concentration of glycerol and temperature within a limited range. The pH optimum for gelation found out to be 9. Hydrophobic additives were investigated to reduce gelation time.
