Explain, what is meant by an “electrochemical affinity biosensor” and how this differs from an “electrochemical enzymatic biosensor”. What is the general relevance of such electrochemical biosensors to healthcare? Electrochemical Affinity Biosensor Vs Electrochemical Enzymatic Biosensor

Electrochemical Enzymatic Biosensor Vs Electrochemical Affinity Biosensor

A biosensor called an electrochemical affinity biosensor uses an electrochemical transduction process that detects and measures the binding between small molecules and their particular binding molecules. This kind of biosensor measures affinity interactions with high specificity, sensitivity, and is often used in medical diagnostics. The electrochemical enzymatic sensor, however, uses enzymes for recognition to determine the presence and absence of particular analytes. Although this type of biosensor has a higher sensitivity than the electrochemical affinity, it cannot measure all enzymatic reactions. It is possible to detect various biomolecules such as proteins and hormones quickly, accurately, and economically using electrochemical biosensors in healthcare. The result has been a better understanding of disease, faster diagnosis, and a quicker therapeutic response. Electrochemical biosensors can be used, for example, to monitor and detect biomarkers of cancer and cardiovascular disease. These devices have also been applied in point of care testing, which provides quick, accurate results for medical environments (Akhtar and al. 2020). Cont…..
