Abstract: An electrochemical immunosensor employs antibodies as capture and detection means to produce electrical charges for the quantitative analysis of target molecules. This sensor type can be utilized as a miniaturized device for the detection of point-of-care testing (POCT).

What is DNA biosensor?

DNA biosensors, based on nucleic acid recognition methods, are being developed towards the assay of rapid, simple and economical testing of genetic and infectious diseases. Unlike enzyme or antibodies, nucleic acid recognition layers can be readily synthesized and regenerated for multiple uses.

What is electrochemical detection?

Electrochemical detection is a powerful analytical method that can detect electric currents generated from oxidative or reductive reactions in test compounds.

What is electrochemical transducer?

Electrochemical transducer reports changes in form of electrical signal which is directly proportional to the concentration of analyte. Binding of analyte results in ionic discharge, which can then be measured in the form of current or voltage, using suitable transducers. Principle.

Which of the following is a characteristics of electrochemical biosensor?

Which of the following is a characteristic of electrochemical biosensors? Explanation: For a given applied current, electrochemical biosensors study the movement of the electrons in redox reactions detected when a potential is applied between two electrodes.

What are piezoelectric biosensors?

Piezoelectric biosensors are a group of analytical devices working on a principle of affinity interaction recording. A piezoelectric platform or piezoelectric crystal is a sensor part working on the principle of oscillations change due to a mass bound on the piezoelectric crystal surface.

What are electrochemical sensors used for?

Electrochemical sensors are used for detecting oxygen and toxic gases. More specifically, they measure the concentration of a specific gas within an external circuit. This is done by method of oxidation or reduction reactions. These reactions generate the positive or negative current flow through said external circuit.
