“…In particular, contamination of the environment with heavy metal ions poses significant threats to ecosystems [1][2][3]. For example, Au(III) can interact with phospholipid bilayers and perturb the molecular structures of cells, affecting the permeabilities of the cell membranes and the functions of the ion channels, receptors, and enzymes in the membrane lipids [4].…”

A high‐strength fluorescent hydrogel is prepared by physical cross‐linking of carbon nanodots (CNDs) with poly(vinyl alcohol) (PVA). The stretching and compression of the PVA hydrogel are improved with CNDs by 176% and 64%, respectively. It still has excellent self‐healing behaviors without adding other healing agents. In addition, the search for rapid detection of heavy metals is still a huge challenge. The resulting hydrogel exhibits fluorescence quenching in the presence of Fe3+ by the fluorescence characteristics of CNDs, which has high selectivity and sensitivity. The PVA‐CNDs fluorescent hydrogel can be used as a solid detection platform for Fe3+, where the detection limit is found to be 10 µm for Fe3+ by fluorescence studies.

The increase in release of toxic heavy metals into natural water attracts much attention due to its devastating effect on ecology and human health. The design and implementation of green electrode materials is pivotal for improving the electrochemical performance of in situ heavy metal monitoring. This work reviews various novel electrode materials and hybrid materials that improve electrochemical detection. Modified green and novel electrode materials offer better performance due to their improved deposition with wide linear and enhanced response under optimized sensing parameters. In particular, recent works related to gold, carbon materials, bismuth, and metal oxide‐based electrodes are reviewed. The environmentally friendly (“green”) characteristics, as well as their versatility and flexibility, are especially emphasized. In addition, synthesis methods and novel designs of electrode integration are highlighted. Most of the substantial achievements as well as breakthroughs in recent years are surveyed, and the challenges and prospective in this field are also identified.
