Emerging applications in the field of nanotechnology are able to solve a gamut of problems
surrounding the applications of agroecosystems and food technology. Nano Engineered Material
(NEM) based nanosensors are important tools for monitoring plant signaling pathways and metabolism
that are nondestructive, minimally invasive, and can provide real-time analysis of biotic and
abiotic threats for better plant health. These sensors can measure chemical flux even at the singlemolecule
level. Therefore, plant health could be monitored through nutrient management, disease
assessment, plant hormones level, environmental pollution, etc. This review provides a comprehensive
account of the current trends and practices for the proposed NEM related research and its (i)
structural aspect, (ii) experimental design and performance as well as (iii) mechanisms of field application
in agriculture and food system. This review also discusses the possibility of integration of
data from NEM based nanosensors in current and emerging trends of precision agriculture, urban
farming, and plant nanobionics to adopt a sustainable approach in agriculture.
