“…128 Those MIPs that can specifically recognise and remove ions are called ion imprinted polymers (IIPs), these benefit from being broadly applicable, highly selective and watercompatible. 129 IIP-based electrochemical sensors have been reported towards Co 2+ , 130 Cd 2+ 131,132 and others 133 exhibiting ultra-trace levels in water samples.…”

“…Excessive accumulation of heavy metals in the human body will reduce the energy level, and damage the functions of the brain, lungs, kidney, liver, blood components, and other important organs. As a result, the body, especially muscles and nerves, gradually develops degenerative diseases, such as multiple sclerosis, Parkinson's disease, Alzheimer's disease, and muscular dystrophy [2][3][4][5][6].…”

In this study, an ultramicro interdigital electrode array chip (UIEA) was designed and fabricated by using Micro-Electro-Mechanical systems (MEMS) technology, and a portable detection system, using the chip for determination of heavy-metal ions in water, was developed. The working electrode of the UIEA was modified with gold nanoparticles by electrodeposition. The detection sensitivity of the UIEA chip for copper ions was 0.0138 μA·L·μg−1, with the linear range of 0–400 μg/L and the detection limit of 18.89 μg/L (3σ), which was better than that of the compared columnar glassy carbon electrode. The results of the interference experiment verified that the UIEA chip has a certain anti-interference ability against common heavy-metal ions in water, such as Pb2+, Zn2+, and Mg2+ ions. The standard addition method was used to investigate the performance of the developed s ystem for copper ion determination in real water. The recovery range from 87.5% to 94.7% was achieved.

Among electrochemical detection methods, square-wave anodic voltammetry (SW-ASV) is the most popular. However, this method has a number of limitations, for instance, mercury or bismuth electrodes are usually used as a working electrode, which are highly toxic substances. This article is devoted to the study of the use of track-etched membranes based on polyethylene terephthalate as a basis for electrochemical sensors. The modification of the surface of membranes was carried out by the method of photoinitiated graft polymerization of methacrylic acid. Magnetron sputtering with a mask was used to obtain electrodes on both sides of the membrane. The sensor has been tested for sensing toxic cadmium ions in a concentration range of 0.5 to 12.5 mg/L.
