In the past several decades, various types of nanostructured biomaterials have been developed.
These nanostructured biomaterials have promising applications in biomedical fields such as
bone repair, tissue engineering, drug delivery, gene delivery, antibacterial agents, and bioimaging.
Nanostructured biomaterials with high biocompatibility, including calcium phosphate, hydroxyapatite,
and calcium silicate, are ideal candidates for drug delivery. This review article is not intended to
offer a comprehensive review of the nanostructured biomaterials and their application in drug delivery
but rather presents a brief summary of the recent progress in this field. Our recent endeavors in
the research of nanostructured biomaterials for drug delivery are also summarized. Special attention
is paid to the synthesis and properties of nanostructured biomaterials and their application in drug
delivery with the use of typical examples. Finally, we discuss the problems and future perspectives
of nanostructured biomaterials in the drug delivery field.
