The day your crop will send such messages to you are not far… texting their deeds and desires
Yes, that is possible with Nano biosensors. A biosensor is an analytical device used for the detection of an analyte that combines a biological compound with a physicochemical detector. The sensitive biological element like tissues, microorganisms, organelles, cell receptors, enzymes etc., is a biologically derived material. Nano technology allows the introduction of signal transduction technology in biosensors. Because of their sub micron dimensions, nanosensors and nanoprobes and other nano system has allowed simple and rapid analysis in vivo. Portable instruments capable of analysing and detecting multiple components are become available.

Availability of net land and water resources for Agriculture is rapidly declining causing huge losses in agricultural output. Besides the increasing concentration of herbicides, pesticides and heavy metals in Agriculture land is alarming. These issues can be dealt effectively with the adoption of Nano biosensors.
Some cutting-edge applications
- Diagnosis of Soil Quality and Disease Management
Nano biosensors can be used to diagnose soil disease caused by microorganisms such as viruses, bacteria and fungi via measurement of differential oxygen consumption in the respiration of harmless and harmful soil microorganisms. Apart from this biosensors can also predict disease outbreak.
- For Sustainable Agriculture
A nano fertilizer refers to the product that delivers nutrients which is encapsulated within a nanoparticle. Nano fertilizers could be used to reduce nitrogen loss by leaching, emission and long term assimilation by soil microorganisms. Pesticides inside nano particles are developed that can be of a timed release or have release linked with environmental trigger (say during a pest attack). Combined with a smart delivery system, herbicides could be applied only when necessary resulting in greater production of crops and reduced/nil exposure of pesticides to agricultural workers and consumers.
- For Detecting Harmful Contaminants
Several Nano biosensors are designed to detect contaminants, pests, nutrient content, and plant stress due to drought, temperature or pressure. They may also potentially helpful for farmers to enhance competence by applying inputs only when necessary.
Clearly there is an opportunity for Nanotechnology to have a profound impact on agriculture. New prospects for integrating Nanotechnology should be explored for sustainable Agriculture and steady development.
With targeted efforts by government and academics in developing such enabled agro-products, we believe that Nanotechnology and Nano biosensors will be transformative in field of agriculture.
