Biosensors Used in Dentistry: A Review
Keywords:: Biosensors, Types, Applications in Dentistry
A bio-sensor is composed of six elements which include bio-receptor, transfusion element, chemically active
interface, signal amplifier, signal processor and display. The analyze binds to the immobilized biological
material and forms a product. The product linked change is then converted by the transducer into electric
signals which can be amplified and measured. Oral fluid bio-sensors have the advantages of easy accessibility
and noninvasive sample collection, making them a novel method in disease diagnostics. However, its
limitations such as less sensitivity and specificity are overcome by the advent of new technologies such as
microfluidics and nanofluidics. This review article discusses the concepts and applications of biosensors in
the field of dentistry.
