ABSTRACT
Nanotechnology is one of the fastest emerging fields and has a wide range of applications in various aspects. The materials which range from 10 nm to 100 nm in size are known as nanomaterials (NMs). The use of nanoscale materials provides greater surface coverage, better efficiency, and selectivity. Moreover, the surface of NMs can be tuned to attain desired and physical, chemical, and mechanical properties. Therefore, NMs are extensively used in several fields, including agriculture, food science, biomedical sector, energy, and sensor applications. The outline of this chapter is: (i) introduction of nanoscience and nanotechnology; (ii) difference between the nanoscience and nanotechnology and the classification of NMs based on their structural morphology; (iii) nanotechnology for agriculture and biomedical applications; (iv) nanotechnology for energy and sensor applications; and (v) conclusions and opportunities in this exciting and emerging research field.
