“…Significant studies have been undertaken to generate sensors that are efficient in detecting heavy metal ions at trace and ultra-trace concentrations [ 86 , 87 ]. However, challenges such as sensitivity, selectivity, specificity, and interference persist in many available sensors [ 88 , 89 ]. Therefore, considerable efforts must be directed towards enhancing electrochemical and colorimetric nanosensors to achieve better efficiency, accuracy, and specificity, thus enabling reliable and expanded heavy metal ion detection capabilities [ 90 , 91 ].…”

Plant health monitoring is essential for understanding the impact of environmental stressors (biotic and abiotic) on crop production, and for tailoring plant developmental and adaptive responses accordingly. Plants are constantly exposed to different stressors like pathogens and soil pollutants (heavy metals and pesticides) which pose a serious threat to their survival and to human health. Plants have the ability to respond to environmental stressors by undergoing rapid transcriptional, translational, and metabolic reprogramming at different cellular compartments in order to balance growth and adaptive responses. However, plants’ exceptional responsiveness to environmental cues is highly complex, which is driven by diverse signaling molecules such as calcium Ca2+, reactive oxygen species (ROS), hormones, small peptides and metabolites. Additionally, other factors like pH also influence these responses. The regulation and occurrence of these plant signaling molecules are often undetectable, necessitating nondestructive, live research approaches to understand their molecular complexity and functional traits during growth and stress conditions. With the advent of sensors, in vivo and in vitro understanding of some of these processes associated with plant physiology, signaling, metabolism, and development has provided a novel platform not only for decoding the biochemical complexity of signaling pathways but also for targeted engineering to improve diverse plant traits. The application of sensors in detecting pathogens and soil pollutants like heavy metal and pesticides plays a key role in protecting plant and human health. In this review, we provide an update on sensors used in plant biology for the detection of diverse signaling molecules and their functional attributes. We also discuss different types of sensors (biosensors and nanosensors) used in agriculture for detecting pesticides, pathogens and pollutants.

“…Qi and coworkers designed an electrochemical sensor for Cd (II) detection using a complex of carbon fiber paper (CFP), CoMOF, AuNPs, and glutathione as the conductive substrate (CFP/CoMOF/AuNPs/GSH). They achieved Cd (II) detection as low as 1 nM [101]. In a related study, Wang et al employed a covalent organic framework prepared with the condensation of 2,5-diamino-1,4-phenyldicarboxylic acid (DATA), and 2,4,6-triformylphloroglucinol (TP).…”

Human exposure to acute and chronic levels of heavy metal ions are linked with various health issues, including reduced children’s intelligence quotients, developmental challenges, cancers, hypertension, immune system compromises, cytotoxicity, oxidative cellular damage, and neurological disorders, among other health challenges. The potential environmental HMI contaminations, the biomagnification of heavy metal ions along food chains, and the associated risk factors of heavy metal ions on public health safety are a global concern of top priority. Hence, developing low-cost analytical protocols capable of rapid, selective, sensitive, and accurate detection of heavy metal ions in environmental samples and consumable products is of global public health interest. Conventional flame atomic absorption spectroscopy, graphite furnace atomic absorption spectroscopy, atomic emission spectroscopy, inductively coupled plasma–optical emission spectroscopy, inductively coupled plasma–mass spectroscopy, X-ray diffractometry, and X-ray fluorescence have been well-developed for HMIs and trace element analysis with excellent but varying degrees of sensitivity, selectivity, and accuracy. In addition to high instrumental running and maintenance costs and specialized personnel training, these instruments are not portable, limiting their practicality for on-demand, in situ, field study, or point-of-need HMI detection. Increases in the use of electrochemical and colorimetric techniques for heavy metal ion detections arise because of portable instrumentation, high sensitivity and selectivity, cost-effectiveness, small size requirements, rapidity, and visual detection of colorimetric nanosensors that facilitate on-demand, in situ, and field heavy metal ion detections. This review highlights the new approach to low-cost, rapid, selective, sensitive, and accurate detection of heavy metal ions in ecosystems (soil, water, air) and consumable products. Specifically, the review highlights low-cost, portable, and recent advances in smartphone-operated screen-printed electrodes (SPEs), plastic chip SPES, and carbon fiber paper-based nanosensors for environmental heavy metal ion detection. In addition, the review highlights recent advances in colorimetric nanosensors for heavy metal ion detection requirements. The review provides the advantages of electrochemical and optical nanosensors over the conventional methods of HMI analyses. The review further provides in-depth coverage of the detection of arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) ions in the ecosystem, with emphasis on environmental and biological samples. In addition, the review discusses the advantages and challenges of the current electrochemical and colorimetric nanosensors protocol for heavy metal ion detection. It provides insight into the future directions in the use of the electrochemical and colorimetric nanosensors protocol for heavy metal ion detection.

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.
