Biosensors are devices comprising a biological element and a physiochemical detector that are used to detect analytes. These instruments have a wide range of applications ranging from clinical through ...

Brazilian researchers have developed an electrochemical sensor that can detect pancreatic cancer in its early stages. The device identifies the biomarker molecule CA19-9, which is associated with the ...

Since its origins in the 1960s, the biosensors field has grown to encompass a wide range of sensors, from enzyme-based to immunosensors to thermal biosensors. Along with this, a diverse set of ...

Schematic of a generic biosensor architecture. The target analyte interacts with an immobilized bioreceptor layer, and the resulting molecular recognition event is translated by a physico-chemical ...
