Chemical Sensors for Heavy Metals/Toxin Detection

Abstract

Nowadays, the huge release of pollutants into the environment has become a significant problem in many countries and entire regions [...]

Electrochemical study of the Cu²⁺ sensor based on ZIF-67/MWCNTs/Nafion

“…Heavy metals are highly toxic and difficult to be degrade, posing a serious threat to the environment and human health [1]. Although copper ions are an essential trace element of the human body, excessive participation will cause damage to human function.…”

An Experimental and Quantum (QTAIM) Performance Study of a Proposed Molecular Chemosensor: A Quinazolinone‐Based Sensor for Hg2+ Ion Detection

“…At present, fluorescence spectroscopy is a frequently used technique for detecting ions in biological and environmental media [17–20] . Today, the design and fabrication of chemical sensors have been considered in the selective detection of ions due to their low cost, high sensitivity, selectivity for analysis, and non‐destructiveness [21–25] . The operation of these sensors is through electron transfer processes.…”

“…[17][18][19][20] Today, the design and fabrication of chemical sensors have been considered in the selective detection of ions due to their low cost, high sensitivity, selectivity for analysis, and nondestructiveness. [21][22][23][24][25] The operation of these sensors is through electron transfer processes. Chemical sensors can be studied in two categories: fluorescent chemical sensors and colorimetric chemical sensors.…”

Dioxepine-Peri-Annulated PMIs—Synthesis and Spectral and Sensing Properties

“…On the other hand, depending on the absorbed dose, they may be a major threat to the health and life of living systems [ 2 ]. There are plenty of scientifically proven environmental and health effects of metals, their cations, and their complexes, as well as several myths about their toxicity [ 3 ], but it is inarguable that their qualitative and quantitative detection is of utmost importance [ 4 ]. One of the most versatile and promising techniques for detecting and quantifying cations of interest are fluorescent sensors [ 5 ], which are capable of changing their emissions upon specific binding with the target analytes [ 6 ].…”
