Role of Nanosensors in agriculture

Nano-biosensors play an important role in revolutionizing farming through the development of diagnostic tools and techniques. These sensors are accurate, efficient, and cost-effective in dealing with various food, agriculture, and environmental issues. Some of the sensor applications in agriculture include the identification of heavy metal ions, pollutants, microbial load, and pathogens, along with rapid temperature, traceability, and humidity monitoring. In this review study, we are analyzing the selective nature of nanosensors for the target of molecules with immobilized bio receptor probes and various specific agricultural applications. These nanosensors have unique characteristics that make them important for the agricultural industry such as small size, compact, effective, unique, sensitive and relatively inexpensive. These sensors are placed on the leaves of the plant where hydrogen peroxide signaling waves are observed. Plants use Hydrogen peroxide (H2O2) inside their leaves to communicate. They send signals that activate the leaf cells to create compounds that help fend off predators, such as insects, to fix them. Nano sensors consist of nanoscale particles such as nanoscale wires (high sensitivity to detection), carbon nanotubes (high surface area), thin films, nanoparticles and nanomaterials from polymers. These sensors detect the change in the conductance when a semiconducting carbon nanotube is exposed to certain chemicals. In our review study, we are analyzing the application and role of nanosensors in agriculture and crop protection. Thus, nanosensors play an vital role in crop protection and promoting the concept of sustainable agriculture and will be discussed in this study.
