What are Smart Biomaterials?
Smart biomaterials are advanced materials designed to interact in a pre-defined manner with biological systems. These materials respond to environmental stimuli such as temperature, pH, and light, making them particularly useful in biomedical applications. The integration of nanotechnology enhances their capabilities, enabling precision at the molecular level.
How Does Nanotechnology Enhance Biomaterials?
Nanotechnology allows for the manipulation of materials at the nanoscale, which can significantly improve their properties. This includes increased surface area, enhanced mechanical properties, and the ability to tailor the material’s interaction with biological molecules. Nanotechnology enables the creation of
nanostructured surfaces that can, for example, promote cell adhesion or deliver drugs in a controlled manner.
