What are the Techniques for Biomarker Detection Using Nanotechnology?
Several techniques leverage nanotechnology for biomarker detection:
1. Optical Biosensors: Utilize the unique optical properties of nanomaterials for detecting changes in light absorption, fluorescence, or scattering. 2. Electrochemical Biosensors: Employ nanomaterials to enhance the sensitivity and selectivity of electrochemical measurements. 3. Magnetic Biosensors: Use magnetic nanoparticles to detect changes in magnetic fields, which can be correlated with the presence of biomarkers. 4. Surface Plasmon Resonance (SPR): This technique measures changes in the refractive index near the surface of a sensor chip, enhanced by nanomaterials.
