Nanotechnology improves detection limits by leveraging the unique properties of nanomaterials. These materials often exhibit exceptional electrical, optical, and mechanical properties that can be finely tuned to interact with target analytes. For instance:
- Increased Surface Area: Nanomaterials possess a high surface-to-volume ratio, providing more active sites for analyte interaction. - Quantum Effects: At the nanoscale, materials can exhibit quantum effects that enhance their reactivity and sensitivity. - Enhanced Optical Properties: Nanoparticles can enhance signal detection through surface plasmon resonance (SPR) and other optical phenomena.
