What are the Common Methods for Signal Enhancement?
Several methods are commonly used for signal enhancement in nanotechnology:
1. Surface-Enhanced Raman Scattering (SERS): This technique uses metallic nanoparticles to amplify the Raman scattering signal of molecules. 2. Fluorescence Enhancement: Utilizing quantum dots or metallic nanoparticles to enhance the fluorescence signal. 3. Electrical Signal Amplification: Using nanowires or carbon nanotubes to improve the electrical conductivity and, consequently, the signal. 4. Magnetic Signal Enhancement: Employing magnetic nanoparticles to enhance signals in magnetic resonance imaging (MRI) or other magnetic sensing techniques.
