Recent advances in electrochemical biosensors – A brief review

A sensitive biological system and a detector system with appropriate transducers for obtaining the output signals make up a biosensor. These devices have a wide range of uses, including disease screening, the detection of environmental pollutants, agriculture, and routine medical examinations. The product's selectivity, sensitivity, stability, and lower production costs will all be critical factors in its widespread commercialisation. Recently, scientists have tackled the issue of developing a nano biosensor with a high degree of sensitivity and selectivity for the recognition of biomarkers of immune responses and cancer. The fact that electrochemical nano biosensors may successfully be employed for detecting…
