The biosensor's main purpose is to detect the analyte, which is the target molecule in a sample. This specific biomolecule's presence is usually important in some way, whether it be signal that indicates disease, a cell process, or contamination. Thus, scientists developed biosensors with specific bioreceptors to detect and measure its concentration.
A target analyte can join to the bioreceptor in one of two ways: it can either bind specifically to a bioreceptor that can only accept that one analyte, or bind nonspecifically to an bioreceptor that could accept one or two analytes depending on how similar they are. Although achieving a perfect fit through specific binding is desirable, it is more common to get nonspecific binding due to the various charges and attraction and repulsive forces the molecules may have.
