Biosensorët

Biosensorët are analytical devices that combine a biological recognition element with a physicochemical transducer. This combination allows for the detection and quantification of specific biological or chemical substances. The biological component, such as an enzyme, antibody, nucleic acid, or microorganism, is responsible for selectively binding to the target analyte. This binding event then triggers a measurable change. The transducer, which can be electrochemical, optical, mass-based, or thermal, converts this biological recognition event into a signal that can be interpreted. For example, an electrochemical biosensor might detect a change in current or voltage generated by an enzymatic reaction, while an optical biosensor could measure a change in light absorption or fluorescence. Biosensorët find applications in diverse fields, including medical diagnostics for disease monitoring, environmental monitoring for pollutant detection, food safety for microbial and chemical contaminant analysis, and industrial process control. Their advantages include high specificity, sensitivity, rapid response times, and the potential for miniaturization and point-of-care use. Research continues to focus on improving their stability, shelf-life, and cost-effectiveness, as well as expanding their range of detectable analytes and applications.
