What Are Some Techniques Used in Nanotechnology for Detection?
1. Surface Plasmon Resonance (SPR): Utilizes the oscillation of electrons on the surface of nanoparticles to detect molecular interactions. 2. Electrochemical Sensors: Employ nanomaterials like graphene to improve electron transfer rates, enhancing sensitivity. 3. Fluorescence-Based Sensors: Utilize quantum dots for their superior brightness and photostability compared to traditional dyes. 4. Nanomechanical Sensors: Use changes in the mechanical properties of nanomaterials to detect the presence of substances at very low concentrations.
