Combine an electrical interface (trans- ducer) with the biologically sensitive and selective element More specifically, a biosensor contains a bioreceptor, which is a biomolecule that recognizes the target analyte. The trans- Biosensor/transducer ducer portion of the biosensor converts the recognition event into a measurable signal that correlates with the quantity or presence qualification: of the chemical or biological target that can cause physiological damage. A generalized biosensor model is illustrated in Figure 1. a critical step for Performance criteria for a biosensor sys- tem include: homeland security 1. Speed and ease of use (testing/calibra- tion/maintenance) by non-technical per- sonnel 2. Selectivity (to target analyte) 3. Sensitivity/resolution
