• Intelligence Education and Research, Hanyang University, Ansan 426-791, South Korea 10.3762/bjnano.13.92 Abstract Biomimetic materials for better bone graft substitutes are a thrust area of research among researchers and clinicians. Autografts, allografts, and synthetic grafts are often utilized to repair and

• tissue engineering applications. Keywords: antibacterial activity; biomimetic materials; bone graft substitutes; chitosan; gold; osteoinductive; silver; Introduction Bone-related defects and diseases are a serious concern to the life of patients [1]. Autografts, allografts, and synthetic grafts are

• frequently utilized by clinicians to treat bone defects. Bone grafts should have osteoconductive, osteoinductive, and osteogenic properties to mimic the natural function of the bone [2]. Autografts are considered the gold-standard bone graft substitute since it has all three properties previously mentioned

This new approach can be effectively applied for fabrication of biocompatible scaffolds for bone tissue engineering constructions.

• popular biomaterial because of a number of key advantages: convenient precursors, nontoxic, excellent biocompatibility and appropriate biodegradability [5][6][7]. Additionally, CPs are widely used for bone graft substitution due to their chemical affinity to the bone mineral content [8]. One of the
