Designing the Next Generation of Biomaterials through Nanoengineering

Abstract

Abstract Recent advances in biomaterials science have applied nanoengineering to develop biomaterials with superior properties and tailored functionalities. These unique attributes are achieved due to the ability of nanoengineering to provide precise control over material interactions with living systems at the molecular scale. Here, key nanotechnologies employed to develop the next generation of biomaterials are critically evaluated. A diverse range of nanomaterials, differing in base materials, shapes, sizes, or surface properties can be integrated into various fabrication processes to develop these advanced biomaterials. Further investigation is required into properties such as surface energy, defects, porosity, and crystallinity, as these critically influence the physical, chemical, and biological characteristics of nanoengineered materials. Consequently, we explore diverse biomedical applications of nanoengineered biomaterials, including regenerative medicine, biomolecular delivery, additive manufacturing, immune engineering, cancer therapeutics, bioimaging, biosensing, antimicrobial devices, and tissue adhesives. Additionally, their current limitations are analyzed and emerging strategies for designing the next generation of nanoengineered biomaterials are highlighted.
