Nanotechnology is the branch of technology that manipulates matter on an atomic or molecular scale. Materials, devices, or structures are dened as “nano” when they have at least one dimension that ranges from 1 to 100 nm. Nanomaterials often have different physical (mechanical, electrical, optical, etc.) properties compared to the same material at macrodimensions. Nanostructured biomaterials have the advantage of small size, high porosity, and most importantly a high surface-area-to-volume ratio (Ngiam et al. 2011). The increased surface-area-to-volume ratio alters the mechanical, thermal, and catalytic properties of materials. These new properties allow unique and innovative applications of nanomaterials in many elds.
