Overview of Biosensing

Overview

Biosensors are devices that use a wide range of biological processes and physical properties in order to detect either a biological molecule, such as a protein or cell, or a non-biological molecule, such as a chemical component or contaminant. This interdisciplinary field utilizes electrical, optical, electrochemical, or even mechanical properties to detect the presence of the target molecule.

This video introduces the field of biosensing, and reviews common types of biosensor technologies. This video also discusses key challenges in the field, and provides insight into how biosensors are used in the field.

Procedure

Biosensors have revolutionized the fields of medicine and biotechnology through the detection and characterization of target molecules in complex biological fluids. A biosensor is a device that uses a biological receptor molecule, such as an enzyme, to detect a specific compound. Biosensors use different methods, such as electrochemistry, mechanical properties, or optics, to detect the binding of the specific molecule to the receptor. This video will introduce biosensors and the biosensing field by di
