“…Toxic heavy metals in water are an important contributor to human health [ 18 ]. Hiba et al used a natural ion carrier, lignin, to modify the Pt electrode for the detection of Pb 2+ ions, and analyzed the output response of the constructed electrochemical sensor using EIS [ 19 ]. Figure 2 b shows the Nyquist curves for different concentrations of Pb 2+ ions (10 −9 –10 −4 M) in the range of frequency of 100 mHz–100 kHz, using which the curves of calibration of the impedance values and concentrations of the Pb 2+ ion at a fixed excitation frequency (1 Hz) were plotted.…”

The growing concern over heavy metal contamination in environmental and industrial settings has intensified the need for sensitive, selective, and cost-effective detection technologies. Electrochemical sensors, due to their high sensitivity, rapid response, and portability, have emerged as promising tools for detecting heavy metals. Recent years have seen significant progress in utilizing biopolymer-based materials to enhance the performance of these sensors. Biopolymers, derived from renewable raw materials, have garnered considerable interest in both science and industry. These biopolymer-based composites are increasingly recognized as superior alternatives to conventional non-biodegradable materials because of their ability to degrade through environmental exposure. This review provides a comprehensive overview of recent advancements in biopolymer-based electrochemical sensors for heavy metal detection. It discusses various types of biopolymers and bio-sourced polymers, their extraction methods, and chemical properties. Additionally, it highlights the state of the art in applying biopolymers to electrochemical sensor development for heavy metal detection, synthesizing recent advances and offering insights into design principles, fabrication strategies, and analytical performance. This review underscores the potential of biopolymer-based sensors as cost-effective, eco-friendly, and efficient tools for addressing the pressing issue of heavy metal contamination in water and discusses their advantages and limitations. It also outlines future research directions to further enhance the performance and applicability of these sensors.
