SOYBEAN-BASED THERMOPLASTICS AS BIOMATERIALS

摘要

The invention provides thermoplastic materials for biomedical applications through the processing of soybean de-fatted Tofu cheese. The material films show a relatively high degree of water uptake from the dry state as well as good tensile strength and elastic modulus when tested in wet conditions. The materials minimisein vitro the humoral and cell-mediated inflammatory response, promote the formation of calcium phosphate crystals and undergo a slow degradation in buffer systems. Adhesion and proliferation of tissue cel ls are also favoured by this natural composite material.
