“…Nanomaterials show considerable promise for developing non-enzymatic electrochemical sensors. These include various categories such as nanoparticles (e.g., CuO, CuO–TiO 2 , ZrO 2 , and NiO); nanocomposite (e.g., molybdenum); and peptide and carbon nanotubes, which are extensively utilized for electrochemically detecting residual pesticide particles [ 58 ]. The thorough study of residual pesticide particles using such nanomaterials is attributed to their extremely small size, large surface area, and unique electrical and chemical properties.…”

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.

The development of sensors for the detection of different substances is a worldwide demand. Nanotechnology has allowed great advances in this area in an attempt to bring new possibilities. Sensors with perovskite and spinel structures have been widely investigated and demonstrated interesting performances, due to their fascinating optical, magnetic, and electrical properties. Despite this advancement, some limitations and drawbacks have to be resolved. Moreover, the combination of such structures with graphene derivatives has attracted particular attention in recent years; so far the obtained results manifest improved sensors’ performance, thanks to the effective combination of their individual properties. This comprehensive review aims to highlight the recent advances in Electrochemical and Biological nanosensors based on spinel and perovskite structures without and with graphene derivatives, by presenting sensing applications of diverse substances alongside advantages and futures challenges.
