Defining a Standard for Characterizing Biosensor Performances

Though a biological recognihon reaction is typically very selective, interferences may occur due to substances other than the analyte of interest. Such interferences can be converted by the biorecognition element or at the transducer surface and 

In addihon to selechvity, sensitivity (S) is a vital parameter of the performance of a biosensor. Sensihvity is defined as the slope of change in signal with change in concenhahon  

This is, however, only straightforward if the sensor response is hnear. 

The limit of detection (LOD) of a biosensor is one of the most important parameters to be determined. That holds especially true when disease markers have to be determined. The LOD is typically defined as 

Terms rarely mentioned in the biosensor literature are accuracy and precision.
