RADIATION SYNTHESIS AND FABRICATION FOR BIOMEDICAL APPLICATIONS

Radiation synthesis and fabrication techniques can make various specific forms and structures of materials enhancedly which are useful for biomedical applications, Those materials are a porous gel and membrane, an interpenetrating networked(IPN) hydrogel, a heterogeneous surface phase membrane,an ultra-thin membrane, a biofunctional laminate and an ultra-fine particle. Radiation techniques can attach various biofunctionalities to those materials effectively by means of immobilization of biofunctional components such as enzymes,proteins,hormones,drugs:,microbial cells and tissue cells, It is convenient that the immobilization can be finished at the same time as the synthesis and fabrication in many cases, The applications to bioreactors,biosensors, artificial organs, drug delivery systems and recently to signal responsive chemical delivery systems, have been studied and developed based on those techniques.
