Several strategies are employed to achieve high selectivity in nanotechnology:
1. Surface Functionalization: Modifying the surface of nanoparticles with specific functional groups or ligands can enhance their selectivity towards particular targets. 2. Shape and Size Control: The shape and size of nanoparticles can be tailored to fit specific targets, improving selectivity. For example, rod-shaped nanoparticles may be more effective in targeting certain cell types than spherical ones. 3. Chemical Composition: The inherent chemical properties of nanomaterials, such as their affinity for certain molecules, can be exploited to achieve high selectivity.
