Definition of a biosensor
A biosensor:
A device that uses specific biochemical reactions mediated by isolated enzymes, immunosystems, tissues, organelles or whole cells to detect chemical compounds usually by electrical, thermal or optical signals.
Common signal error sources
Inhomogenous sample
Bubbles/flow artifacts
Temperature
Electromagnetic interferance
Electronic unstability
Unstable chip/detection layer
