Achieving multifunctionality involves several strategies: 1. Surface Modification and Functionalization: By modifying the surface of nanomaterials, one can introduce various functional groups that can interact with different biological or chemical entities. This is often done using click chemistry or other bioconjugation techniques. 2. Core-Shell Nanostructures: These structures consist of a core material that provides a primary function, surrounded by a shell that adds additional functionalities. For instance, a magnetic core can be used for imaging, while the shell can carry therapeutic agents. 3. Hybrid Nanomaterials: Combining different types of nanomaterials can result in a single composite with enhanced multifunctionality. For example, integrating carbon nanotubes with metal nanoparticles can create materials that are both electrically conductive and catalytically active.
