Learn more: what is a biosensor?
A biosensor is an integrated receptor-transducer device, capable of providing selective quantitative analytical information using a biological recognition element. It transforms chemical information into an analytically useful signal, thanks to its two basic components, which are connected in series: a biological recognition system and a physicochemical transducer.
The recognition system translates information from the biochemical domain, typically an analyte concentration, into a chemical signal, with a high degree of selectivity for the analyte to be measured.
The transducer part of the sensor transfers the output signal of the recognition system to the electrical domain, with the biological recognition element being in direct spatial contact with the transducing element.
Finally the transducer is coupled to an electronic system for signal elaboration and data processing. There are several types of biosensors, depending on the recognition system used (enzymes, antibodies, whole cells, etc.) or the mode of signal transduction (amperometric, potentiometric, field-effect or conductivity sensors). In the case of enzymatic biosensors, one or more enzymes are immobilized on the transducer element (typically a metal electrode) and they catalyze a reaction with high selectivity for the substrate to be measured. Transient or steady-state responses are then monitored by an integrated detector.
Amperometric sensors are based on the measurement of the current resulting from the electrochemical oxidation or reduction of an electroactive species. It is usually performed by maintaining a constant potential at a metal or carbon based working electrode, or an array of electrodes with respect to a reference electrode. The resulting current is directly correlated to the bulk concentration of the electroactive species. Biocatalytic reaction rates are usually chosen to be first-order dependant on the bulk analyte concentration, which therefore results to be linearly proportional to such steady-state currents.
