Cephradine Intercalated Mg-Al Layered Double Hydroxide

Abstract

Engineered advanced functional materials are promising candidates for biotechnology and biomedical science. Mg-Al layered double hydroxide (LDH), anionic or hydrotalcite-like clays consist of positively charged layers and exchangeable anions along with water molecules in the interlayer space were synthesized from homogeneous solution of MgCl2and AlCl3by urea induced co-precipitation method. A pharmaceutically important drug, cephradine was intercalated with synthesized LDH in alkali media (pH 10) by in-situ technique. Characterizations of the products were carried out using Attenuated Total Reflectance Infra-red (ATR-IR), Energy Dispersive X-ray (EDX) and X-ray Diffraction (XRD) spectroscopy. Scanning electron morphological images envisaged a distinct crystalline and amorphous phases of Mg-Al LDH before and after modification with cephradine. Intercalation of bioactive molecules with LDH would enhance their stability providing sustained release behavior in physiological environment.
