Heavy metals and metalloid pollution poses a severe threat to the environment and human health. Various anthropogenic sources are responsible for the release of these contaminants into the water and food chain of humans and animals. To protect the environment and human health, the detection of heavy metals in various environmental matrices becomes vital. Sophisticated lab-based instruments require more time, effort, and huge investments which warrants the requirement of fieldbased disposable sensors. Various optical and electrochemical sensors are reported to demonstrate good sensitivity, selectivity, and detection limits (LOD). The disposable electrodes comprised of glass, paper, plastic, and fabric are gaining importance owing to the ease of application in field analysis, reproducibility, and low cost. The majority of these sensors are based on noble/precious metals namely gold, silver, and platinum. However, limited availability and high cost of these receptors restrict wide spread applicability of these sensors. Numerous earth-abundant materials and non-noble metalbased sensors are also evolving recently due to several advantages namely large-scale availability, ease of modifications, stability, and shelf life which overcomes the limitations of noble/precious metals-based sensors. The present review provides a review of recent advances in various non-noble and earth-abundant micro and nanomaterials used as receptors in optical and electrochemical biosensors for the detection of metals/metalloids in various matrices. The review also highlights the strategies for the design and fabrication of disposable electrodes, their modification methods, detection strategy, and mechanism involved in the detection of heavy metals. Various gaps existing in the reported sensor systems and future perspectives are also delineated in the present manuscript.

“…It is well known that commercial glassy carbon electrodes (GCEs) are chemically stable and usually utilized as common working electrodes in electroanalysis. However, As(III) is electrochemically inert at the surface of bare GCE, and various nanomaterial modifiers are always required for the electrochemical detection of As(III) on GCE. , Fabrication technologies for chemically modified electrodes, including absorption, covalent binding, crosslinking, and vacuum or semiconductor fabrication methods, among others, the embedded chemically modified electrodes are used due to their sufficient stability, especially for noble-metal-base nanomaterials. − With the thriving of various nanomaterials with excellent electrocatalytic properties, drip coating and other physical methods are widely applied in designing sensitive interfaces due to their simple and easy operation. − However, modified electrodes prepared using some physical methods have problems such as modifier shedding, nonuniformity of active sites, and the inconsistent performance of different batches of modified electrodes, greatly affecting the detection accuracy and stability. ,− The potential stability problem makes it much more challenging to accurately detect As(III) with some modified electrodes. Moreover, most previously reported detection mechanisms are restricted to a specific modified electrode interface. , Therefore, it is crucial to design a practical strategy to achieve accurate and stable detection of As(III) without any nanomaterial modifier and explore general sensing mechanisms.…”

Significant progress has been made in nanomaterial-modified electrodes for highly efficient electroanalysis of arsenic(III) (As(III)). However, the modifiers prepared using some physical methods may easily fall off, and active sites are not uniform, causing the potential instability of the modified electrode. This work first reports a promising practical strategy without any modifiers via utilizing only soluble Fe3+ as a trigger to detect trace-level As(III) in natural water. This method reaches an actual detection limit of 1 ppb on bare glassy carbon electrodes and a sensitivity of 0.296 μA ppb–1 with excellent stability. Kinetic simulations and experimental evidence confirm the codeposition mechanism that Fe3+ is preferentially deposited as Fe0, which are active sites to adsorb As(III) and H+ on the electrode surface. This facilitates the formation of AsH3, which could further react with Fe2+ to produce more As0 and Fe0. Meanwhile, the produced Fe0 can also accelerate the efficient enrichment of As0. Remarkably, the proposed sensing mechanism is a general rule for the electroanalysis of As(III) that is triggered by iron group ions (Fe2+, Fe3+, Co2+, and Ni2+). The interference analysis of coexisting ions (Cu2+, Zn2+, Al3+, Hg2+, Cd2+, Pb2+, SO4 2–, NO3 –, Cl–, and F–) indicates that only Cu2+, Pb2+, and F– showed inhibitory effects on As(III) due to the competition of active sites. Surprisingly, adding iron power effectively eliminates the interference of Cu2+ in natural water, achieving a higher sensitivity for 1–15 ppb As(III) (0.487 μA ppb–1). This study provides effective solutions to overcome the potential instability of modified electrodes and offers a practical sensing platform for analyzing other heavy-metal anions.

A sustainable downscaled procedure using smartphone-based colorimetric determination of manganese (Mn(II)) was developed. This novel Mn(II) determination procedure is proposed using a simple, available microwell-plate platform and a smartphone as a detector. This approach is based on the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) by periodate using Mn(II) as a catalyst. The catalytic kinetics of Mn(II) under different conditions was investigated to determine the optimum condition where the different catalytic activities of various concentrations of Mn(II) evince. Under the optimum condition, the bluish-green product of oxidized TMB, proportioned to the concentration of Mn(II), was monitored using a smartphone camera, and the color signals were processed using ImageJ Software. The developed procedure showed great selectivity and sensitivity as linearity ranged from 1.8 × 10−6 to 4.6 × 10−5 M (0.1 to 2.5 μg/mL). The limits of detection and quantitation were 3.6 × 10−6 and 1.1 × 10−5 M (0.2 and 0.6 μg/mL), respectively. The determination of Mn(II) in freshwater samples was demonstrated to assess environmental water quality as an initial model to more easily promote water management according to the United Nations Sustainable Development Goals (UN-SDGs). The intensity of the red could be successfully applied to evaluate Mn(II) in canals and river water with no significant differences compared with the reference method of Inductively Coupled Plasma Optical Emission Spectrometry at a confidence level of 95%.
