Sensitivity in nanotechnology is often enhanced through several mechanisms:
1. High Surface Area to Volume Ratio: Nanomaterials have a high surface area relative to their volume, which increases their interaction with target molecules. This property is particularly useful in sensors and catalysts.
2. Quantum Effects: At the nanoscale, materials exhibit quantum mechanical properties that do not appear at larger scales. These effects can result in increased electrical, optical, and magnetic properties, improving the sensitivity of devices.
3. Tailored Surface Chemistry: Functionalizing the surface of nanoparticles with specific chemical groups can improve their ability to bind selectively to target molecules, thus increasing sensitivity.
