“…In this regard, a number of analytical techniques such as high-performance liquid chromatography, gas chromatography–mass spectrometry, Raman spectroscopy, etc., are extensively used in food safety laboratories. However, complicated procedures, requirement of expert personnel, and comparatively higher cost have compelled the stakeholders to invest on the development of compact, simple, and efficient sensing devices that could offer a multitude of advantages in terms of precision, selectivity, robustness, easy fabrication, good sensitivity, minimal power requirement, specificity, reproducibility, and short analysis time. − In this context, electrochemical sensors have emerged as analytical tools of ideal choice due to their improved selectivity, miniaturization, and high sensitivity. , …”
