The rapid increase in the world’s population has subsequently increased the demand for food supply. Farmers often lose their agricultural produce due to pathogenic infestations, poor soil conditions, water, and environmental factors. Scientists believe nanobiosensors can play a crucial role in revolutionizing the farming system by determining threats to prevent agricultural loss.

Carbon nanotubes (CNTs) that have been decorated with nanoparticles are effective biological and chemical sensors, photovoltaics, electronic conformal thermal interface substances, and surfaces for heterogeneous catalysis. The particle structure of the sidewalls of the CNT has an effect on the performance and properties of metal-nanotube hybrids for these types of applications.
