СТРУКТУРИРОВАННЫЕ МАТЕРИАЛЫ НА ОСНОВЕ ГИДРОКСИАПАТИТА И ЖЕЛАТИНА ДЛЯ БИОМЕДИЦИНСКОГО ПРИМЕНЕНИЯ

The composite materials hydroxyapatite-gelatin (HA–Gel) and hydroxyapatite-gelatin-Ag (HA–Gel-Ag) were obtained in this work. The estimation of porosity, in vivo testing, surface morphology and phase composition as well as the features of chemical interactions between material components were provided. The main phase in obtained composites is hydroxyapatite (HA). The analysis of IR-spectroscopy results reveals the interaction between hydroxyapatite and silver as well as between gelatin and silver ions in composite materials obtained by co-precipitation from aqueous solutions. The obtained silver-containing composite materials that contain silver are biocompatible and bio-resorbable with high level of porosity (75-85%) and osteoconductive properties. [ABSTRACT FROM AUTHOR]
