Biosensing contaminants of emerging concerns: A technological leap in emerging contaminant detection

Biosensing techniques have been emerging as potent, sensitive, and highly selective techniques to identify contaminants of emerging concern (CECs) in water matrices. The significant levels of these classes of pollutants are extremely detrimental to human health and ecosystems even at trace concentrations. Enzyme-based biosensing techniques utilize the specificity and catalytic activity of enzymes to selectively interact with pollutants, producing measurable signals for their detection and quantification. Here, we summarize different enzyme-driven techniques for the detection of CECs. The use of enzyme-based sensors represents a promising, sustainable approach to address the global challenge of detecting CECs in water matrices.
