Recent progress on the immobilization of biocomponent by radiation polymerization and the application to biomedical uses

Recent Advances in Smart Hydrogels Prepared by Ionizing Radiation Technology for Biomedical Applications

“…The hydrogels prepared by the radiation cross-linking method have favorable swelling, which is important in the biomedical field. Lugo-Medina et al synthesized two NIPAAm hydrogels by chemical cross-linking and electron beam irradiation [ 64 ]. The swelling and shrinkage tests of two types of samples in water and different solutions observed in the swelling and shrinkage of gels prepared by the irradiation method were much higher than those prepared by the chemical cross-linking method.…”

Programming control of intelligent drug releases in response to single and binary environmental stimulation signals using sensor and electroresponsive hydrogel

“…In order to construct the intelligent-type DDS, it is necessary to consider both the sensor function to detect the conditional change in the body and the actuator function to regulate the on-off switching of drug release in response to the sensing results (Santini et al, 1999;Langer and Tirrell, 2004;Kami-Ike et al, 1991). The stimuli-responsive polymer hydrogels are interesting materials for this purpose with both sensing and actuating functions (Kaetsu, 1977;Kaetsu et al, 1986).…”

Preparation and Characterization of Gamma Radiation Cured Gelatin-PVA Bio-Blend

“…[3]. Grafting of gelatin by various polymers has been studied with the objective of improving or modifying the properties of gelatin and in order to develop new materials combining the desirable properties of both natural and synthetic polymer [4,5]. In the present work, thermal and mechanical properties of gelatin-PVA blends and pure gelatin were studied.…”
