Biosensor
Biosensor — An analytical device combining a biological recognition element with a transducer to detect specific analytes, used for real-time peptide binding measurements.
What Is a Biosensor?
A biosensor is an analytical device that combines a biological recognition element (peptide, antibody, enzyme) with a transducer to detect and quantify a target molecule. Peptide-based biosensors use rationally designed peptide sequences as the recognition element, offering advantages in stability, synthesis scalability, and chemical tunability over antibody-based sensors.
Biosensor Formats
- Electrochemical: Peptide immobilized on electrode surface; target binding changes current or impedance
- SPR-based: Real-time label-free detection of peptide-analyte interactions
- Fluorescent: Peptide beacons that change fluorescence upon target binding
- Piezoelectric: Quartz crystal microbalance (QCM) detects mass changes upon peptide-target binding
