Study Notes
Bioelectronics and Biosensors
- Bioelectronics deals with the application of electronics principles to biology and medicine.
- Biosensor is a special type of bioelectronic device used in bioanalysis.
Biosensor Definition and Components
- A biosensor is a compact analytical device incorporating a biological or biologically derived sensing element with a physicochemical transducer.
- A biosensor consists of three basic components: biological recognition system (bioreceptor), transducer, and microelectronics.
- Biosensor operating principles: biological recognition and sensing.
Biosensor Functionality
- The biosensor detects molecular recognition and transforms it into another signal type using a transducer.
- The recognition system provides the sensor with a high degree of selectivity for the analyte to be measured.
- The bioreceptor-analyte interaction produces an effect measured by the transducer, converting it into a measurable signal (e.g., electrical/optical signal).
Biosensor Characteristics and Purpose
- A biosensor is an independently integrated receptor transducer device, providing selective quantitative or semiquantitative analytical information.
- The purpose of a biosensor is to provide rapid, real-time, accurate, and reliable information about the analyte.
- Ideal biosensor characteristics: continuous, reversible, and non-perturbing to the sample.
Biosensor Applications
- Biosensors are envisioned to play a significant analytical role in medicine, agriculture, food safety, bioprocessing, environmental and industrial monitoring.
