A biosensor is an analytical device, used for the detection of a chemical substance, that combines a biological component with a physicochemical detector.
The sensitive biological element, e.g. tissue, microorganisms, organelles, cell receptors, enzymes, antibodies, nucleic acids, etc., is a biologically derived material or biomimetic component that interacts with, binds with, or recognizes the analyte under study. The biologically sensitive elements can also be created by biological engineering.
The transducer or the detector element, which transforms one signal into another one, works in a physicochemical way: optical, piezoelectric, electrochemical,
electrochemiluminescence etc., resulting from the interaction of the analyte with the biological element, to easily measure and quantify.
The biosensor reader device connects with the associated electronics or signal processors that are primarily responsible for the display of the results in a user-friendly way. This sometimes accounts for the most expensive part of the sensor device, however it is possible to generate a user friendly display that includes transducer and sensitive element . The readers are usually custom-designed and manufactured to suit the different working principles of biosensors. As per SNS Insiders Research Report Biosensors Market was valued at USD 28.80 billion in 2022 and is expected to expand at a CAGR of 7.9% from 2023 to 2030 and it will reach USD 52.93 billion in 2030.
