“…Both NT and Poly-PEG-NT were utilized to determine Hg 2+ concentrations in the water samples of pond water. There is always a chance that other elements can cause interferences in environmental samples; keeping this in consideration, the amount of Hg 2+ in samples was estimated with the help of the standard addition method. , NT and Poly-PEG-NT were able to measure the amount of added Hg 2+ accurately with high recovery (Table S2). All of these studies established the effectiveness of both the sensors for quantitative detection of Hg 2+ in environmental samples.…”

Mercury (Hg 2+ )-triggered desulfurization of 1,3dithiolane to the formyl group formation process has been utilized here to develop a norbornene-based reaction-triggered ESIPT active probe (NT). Mercury (Hg 2+ ) activated the excited-state proton transfer (ESIPT) process of both NT and its water-soluble polymer Poly-PEG-NT to change the emission from colorless to cyan-green. Due to the Hg 2+ -sensitive reaction site, NT and Poly-PEG-NT serve as highly selective and ultrafast detection systems with a limit of detection (LOD) of 8.2 nM and 107 nM, respectively. Additionally, NT can detect the organic mercury species (CH 3 Hg + ) with a quick response time and an impressive LOD of 1.1 μM. Due to the water-soluble nature of Poly-PEG-NT, it has the capability of detecting Hg 2+ in pure aqueous meda. Both these probes are capable of detecting Hg 2+ in both environmental and biological systems with excellent efficiency. Overall, the easy synthesis, cost-effectiveness, ultrafast detection, high selectivity, and sensitivity of NT and Poly-PEG-NT toward Hg 2+ /CH 3 Hg + can be used for practical purposes with efficiency to counter mercury toxicity.

“…With a crucial role in environmental, industrial and biological systems, iron and its compounds have widespread industrial applications, including in pigments in paints and plastics, piping material for drinking water, food colouring and coagulants in water treatment [1]. Iron is likewise essential for most life forms, including humans, and plays a vital part as an oxygen transporter in the human body [2, 3]. It also exerts an important effect on the regulation of cell growth.…”

“…Many analytical methods for determining ferric ions have been reported including high‐performance liquid chromatography [10], chemiluminescence [11], potentiometric titration [12], UV‐visible spectrophotometry [2, 13–15], spectrofluorimetry [3, 16–18], atomic absorption spectrometry [19], inductively coupled plasma mass spectrometry [20, 21] and voltammetry [22–31]. Whereas some of those methods pose certain disadvantages – time‐intensive analysis and matrix interference – that require sophisticated, expensive equipment as well as time‐consuming extraction and pre‐concentration, voltammetric ones are relatively inexpensive, fast, selective and sensitive.…”

A novel, simple, rapid, inexpensive, highly sensitive voltammetric method developed for determining ferric ions with quercetin in water samples and iron supplements using a disposable bare pencil graphite electrode is described. The limit of detection and analytical ranges for the ferric ions were 3.6 nM and 17.9–716.0 nM, respectively. The results with the water samples were compared with those obtained from a potentiometric auto‐titration system, and the method's accuracy was tested using certified reference material. The complex stoichiometry and electrode reaction were also systematically investigated with UV‐visible spectrophotometry, 1H‐NMR spectroscopy and voltammetry.

“…Being a small molecule, it has certain limitations and disadvantages, like sensitivity, real-time detection, and in-field applications, which restrict its application in a real field. Whereas polymer-based macromolecular sensors are preferred due to their distinctive nature of detection technique, novel side chain interaction, and excellent biocompatibility for in vivo study. − …”

Even though heavy and transition metals originated in the earth’s crust, the significant human exposure and environmental pollution consequences of anthropogenic activities include industrial production and waste, mining and smelting operations, and agricultural and domestic usage of metals. Because of their nonbiodegradable nature, heavy metal ions such as Cu2+ accumulate very quickly in plants and edible animals, ultimately ending up in the human food cycle. Therefore, to nullify the detrimental effects of Cu2+ ions for the sake of the environment and living organisms, we are motivated to design a sensor molecule that can not only detect Cu2+ ions but also remove them selectively from the water medium. To detect the Cu2+ ions, we synthesized a monomer (NCu) and its biodegradable caprolactone-based polymer (PNCu). It was observed that both NCu and PNCu showed higher selectivity toward Cu2+ ions by changing the color from colorless to yellow, with a limit of detection value of 29 nM and 0.3 μM. Furthermore, removing the Cu2+ ions from the water solution was also accomplished by introducing the hydrophobicity of the polymer (PNCu) through the ring-opening polymerization process. Due to increased hydrophobicity, the polymer produced a yellow color precipitate upon adding Cu2+ ions to the solution; thus, removal of the metal ion is possible using our designed polymer and its detection ability. We checked the removal efficiency of our polymer by using UV–vis spectroscopy and EDX analysis, which indicated that almost all of the copper is removed by our polymer. Therefore, to our knowledge, this is the first biodegradable caprolactone-based polymer for colorimetric turn-on detection and separation of the Cu2+ ions from the water.
