What are the Key Components of a Nanotechnology-Based Biosensor?
A typical nanotechnology-based biosensor comprises:
1. Bioreceptor: This is a biological recognition element, such as enzymes, antibodies, nucleic acids, or cells, which specifically interacts with the target analyte. 2. Transducer: This component converts the bioreceptor-analyte interaction into a measurable signal. Nanomaterials like quantum dots, graphene, and nanowires are often used as transducers. 3. Signal Processor: It processes the signal into a readable output. 4. Display: This part presents the processed signal in a user-friendly format.
