Review demonstrates nano-based biosensor applications for detecting biotic and abiotic stresses in crop plants, indicating strong potential for precision agricultural management.
With the confluence of various disciplines, advanced technologies have cropped up. Nanotechnology has developed various emerging devices such as nano-biosensors. A nano-biosensor is a small analytical system possessing multifaceted applications in the field of agriculture, health, environment and quality control. In agriculture, it has shown tremendous potential for simple and fast methods of plant disease detection and identification. In this review we discuss the applications of biosensors in modern agriculture and their role in diagnosing and managing biotic and abiotic stresses in plants. It has been a topic of keen interest among researchers to investigate the potentiality of biosensors in plant stress management. Nano-based biosensors in agricultural stress management encompass various biomasses like metals, electrodes, etc. The review also focuses on the extensive use of nano-based biosensors in plant disease detection and elucidation of metabolic factors involved at the cellular level. There seems to be a significant untapped potential in using biosensors of nano origin for use in plant sciences. The literature suggests that nano-based biosensors will be the future forerunners in plant stress diagnosis. Comprehensively, this review elucidates various high throughput methodologies to mitigate various plant stresses and the various achievements in developing nano-inspired biosensors in plant stress biology.
