How different atoms can be arranged in a way which decides how strong or weak it would be? When we modify materials at their atomic and molecular level, some very unusual and useful properties are generated. Since the dimensions of atoms and molecule are in nanometers, this technology is called nanotechnology. Multiple institutions like Department on Information Technology (DoIT), Defence Research and Development Organisation (DRDO), Council of Scientific and Industrial Research(CSIR) and Department of Biotechnology (DBT) provided the funding to researchers, scholars and projects. National Centers for Nanofabrication and Nanoelectronics were started in Indian Institute of Science, Bangalore and Indian Institute of Technology, Mumbai. Nanotechnology has the potential to impact many aspects of food and agricultural systems. Food security, disease treatment delivery methods, new tools for molecular and cellular biology, new materials for pathogen detection, and protection of the environment are examples of the important links of nanotechnology to the science and engineering of agriculture and food systems. But NANOTECHNOLOGY also have shortcomings like: Free Radical formation aggravation Nutrient Toxicity Unnatural in nature, so the effects can’t be stated Transition of nano particles in placenta in pregnant mothers and effects on breast milk quality DNA or Biological changes due to prolong intake of nanoparticles Mercury, titanium oxide, metal toxicity or poisoning Interaction of nanoparticles with each other and with in the body Degradability Financial effects or Affordability to general population Applicability: As they say….One size doesn’t fit all These can be taken care of by assuring Safety, Regulatory compliance and Affordability.
