Biomedical Applications of Silk Protein

Silk protein has been investigated by many researchers to apply to biomedical field. We reviewed biomedical applications of silk protein such as matrix of wound dressing and drug delivery system. Since silk fibroin/ poly (ethylene glycol) (PEG) semi-interpenetrating polymer networks showed good mechanical properties and wound healing phenomena, it can be used as wound dressing materials. Sericin nanoparticles pre- pared by conjugation with PEG and silk protein/ poloxamer mixture gel are expected to become a deliv- ery as matrix for hydrophobic drug.
