Nanodiamond in composite: Biomedical application.

The biocompatibility of materials is the determining factor for them to be applied in biomedical areas. Nanodiamond (ND) has gained increasing interest in this area due to its biocompatibility, ease of surface functionalization and excellent mechanical performance. ND has been widely used to reinforce biopolymers, and the resultant biocomposites have found applications in bone tissue engineering, chemotherapeutic drug delivery, and wound healing. Fluorescent ND, when combined with biopolymers, is serving for bioimaging and sensing applications. Herein, we contribute a description of ND, recent trends in its adoption for biopolymers, functionalization methods, amalgamation techniques of ND with biopolymers, potential applications of these composites in the biomedical field and future perspectives.
