How is surface chemistry applied in nanotechnology?

Here’s a explanation of how surface chemistry is applied in nanotechnology:

Applications of Surface Chemistry in Nanotechnology

1. Nanoparticle Stabilization
   • Tiny particles have large surface area, which makes them unstable.
   • Surface chemistry helps coat or modify surfaces to prevent clumping.
2. Catalysis
   • Nanoparticles are used as catalysts in reactions.
   • Surface properties control reaction rates and selectivity.
3. Drug Delivery
   • Nanoparticles can carry drugs to specific sites in the body.
   • Surface chemistry allows targeting and controlled release.
4. Sensors
   • Nanosensors detect small changes in chemicals.
   • Surface interactions make them highly sensitive.
5. Material Design
   • Surface modification improves adhesion, wettability, or optical properties.
   • Used in coatings, electronics, and biomedical devices.
