What Are Some Techniques Used in Nano-based Pathogen Detection?
Some commonly used techniques include:
Surface Plasmon Resonance (SPR): Utilizes the optical properties of metallic nanoparticles to detect changes in refractive index upon pathogen binding. Fluorescence-based Assays: Use fluorescent nanoparticles like quantum dots to label pathogens, allowing for their detection under specific lighting conditions. Electrochemical Sensors: Employ conductive nanomaterials like graphene or carbon nanotubes to monitor changes in electrical signals upon pathogen interaction.
