Abstract
Hydroxyapatite (HAp) is an important biomaterial widely used as implants for bone and teeth. Biomaterial with antibacterial activities beneficial to prevent infection post implantation. Therefore, the present study aims to synthesized and characterized HAp composite with zinc oxide (ZnO) that has antibacterial properties. The HAp was synthesized through wet precipitation method using shell of Bellamya javanica as source of calcium. The zinc oxide was added with HAp using in situ method. The crystallinity of the material was decreased after added with ZnO which indicate Zn ion suppressed the crystal growth. Antibacterial abilities were tested against Eschericia coli and Staphylococcus aureus. Inhibition against bacteria increased when the HAp was composited with ZnO. The HAp-ZnO composite showed better inhibition toward Escherichia coli.
