An interesting field within the broad subject of biomaterials is the chemical and physical crafting of materials that can functionally substitute or help regenerate the organs and tissues of the human body. Regeneration is the new dimension of this field as opposed to the more established area of permanent implants and devices to substitute natural structures and functions. With the advent of nanoscience, the field is experiencing a renaissance by embracing the vision that artificial nanostructures of the self-assembling type could be designed for highly specific functions to promote regenerative processes.
