With the rapid development of modern industry, lead is widely used in all walks of life, and its harm to the environment is increasing. Due to the enrichment of heavy metals, the damage lead causes to human health is also growing. As such, rapid and sensitively detection of lead ion (Pb2+) has become an urgent problem to be solved in analytical and environmental disciplines. In recent years, electrochemical methods have received extensive attention in the detection of Pb2+ due to their unique advantages of high sensitivity, selectivity, and low cost. This review first explains the severe harm of Pb2+ to the human body, then goes into detail on the different electrochemical methods for Pb2+ detection. Afterwards, it comprehensively reviews the recent developments in electrochemical sensing of Pb2+ by using different electrode surface modifications. Finally, the challenges and development prospects of Pb2+ detection are outlined.

“…Carbon is a nonmetal of great abundance in the biosphere. Its structure can vary from 0D to 3D, giving it great flexibility and versatility in different applications [ 23 ]. The application of carbon-based nanomaterials for the construction of electrochemical (bio)sensors allows for a decrease in applied overpotentials, a gain in active surface area, and an improvement in charge transfer between the target species and the transducer.…”

Electrochemical sensors consisting of screen-printed electrodes (SPEs) are recurrent devices in the recent literature for applications in different fields of interest and contribute to the expanding electroanalytical chemistry field. This is due to inherent characteristics that can be better (or only) achieved with the use of SPEs, including miniaturization, cost reduction, lower sample consumption, compatibility with portable equipment, and disposability. SPEs are also quite versatile; they can be manufactured using different formulations of conductive inks and substrates, and are of varied designs. Naturally, the analytical performance of SPEs is directly affected by the quality of the material used for printing and modifying the electrodes. In this sense, the most varied carbon nanomaterials have been explored for the preparation and modification of SPEs, providing devices with an enhanced electrochemical response and greater sensitivity, in addition to functionalized surfaces that can immobilize biological agents for the manufacture of biosensors. Considering the relevance and timeliness of the topic, this review aimed to provide an overview of the current scenario of the use of carbonaceous nanomaterials in the context of making electrochemical SPE sensors, from which different approaches will be presented, exploring materials traditionally investigated in electrochemistry, such as graphene, carbon nanotubes, carbon black, and those more recently investigated for this (carbon quantum dots, graphitic carbon nitride, and biochar). Perspectives on the use and expansion of these devices are also considered.

High-efficiency detection technologies of carbaryl residues are significant due to their adverse effects on the environment and human health. To achieve accurate in situ analysis, we designed a portable device integrated with a smartphone sensing platform for rapid, visual quantitative determination of carbaryl via colorimetric and fluorescent signals. Amino-modified gold nanoparticles (AuNPs), blue-emitting silicon quantum dots (Si QDs), and red-emitting cadmium telluride quantum dots (CdTe QDs) were used as opto-sensing centers. The carbaryl triggered the agglomeration of the as-synthesized AuNPs by an electrostatic effect, resulting in a specific change in UV–vis absorption. The blue fluorescence of Si QDs recovered, while the red fluorescence of CdTe QDs quenched, enabling fluorescence color variation from red to blue for visual monitoring. The ratiometric fluorescent signals are available for quantitative analysis in the range of 6 to 200 μM, with a limit of 16.3 nM for fluorescence detection and 49.6 nM for colorimetric sensitivity detection. Coupling widely used three-dimensional print and application software, we constructed the smartphone platform to output the ratio of red and blue channel values of captured fluorescence images to meet the needs of on-site analysis in real samples. This work imposed great improvement in ratiometric sensing for carbamate pesticide residues and broadened the portable quantitative sensing device in chemical sensing applications.
