Nano-Biosensors: NextGen Diagnostic Tools in Agriculture

Nano-biosensors can play an important role in revolutionizing the agriculture through the development of next generation diagnostic tools and techniques. Recently, there has been a remarkable growth in the development of a wide range of biosensors which include electrochemical nanosensors, optical nanosensors, nano-barcode technology, e-Nose and e-Tongue, wireless nanosensors, and wireless sensor network. These biosensors are quite reliable, efficient, and economical in dealing various issues related to food, agriculture, and environment. Nano-biosensors and nano-based systems have some of the unique characteristics such as small size, portable, efficient, specific, sensitive, and relatively inexpensive that make them indispensable for the food and agricultural industries. Moreover, significant amount of research is being undertaken in diagnostics companies and research institutions to develop and improve biosensor technologies for the food and agricultural sector. This has enabled the development of nano-biosensors that can prove to be a very effective tool for smart delivery systems, promoting soil health and disease management. Nano-biosensors are also capable to detect seed viability, shelf life of fruits, and the amount of nutrients required by the plants. Besides, they play an important role in crop protection and promoting the concept of sustainable agriculture. Here, we summarize the recent developments in nano-biosensor technology and its potential role in the sustainable agricultural.
