Why are Surface Charges Important in Nanotechnology?
In the field of nanotechnology, surface charges are essential because they influence a variety of properties and behaviors of nanoparticles:
- Stability: Surface charges help in stabilizing nanoparticles by providing electrostatic repulsion, preventing aggregation. - Reactivity: Charged surfaces can interact more readily with other charged or polar molecules, enhancing reactivity. - Biocompatibility: In biomedical applications, the surface charge can affect cellular uptake and immune response. - Catalysis: Surface charges can influence the catalytic properties of nanoparticles by modifying the electronic environment.
