1991 S. Iijima discovered Carbon Nano tube   for the first time.
1999  1st nano medicine book by R. Freitas“Nano medicine” was published
2000 For the first time National Nanotechnology Initiative was launched
2001 For developing theory of nanometer-scale electronic devices and for synthesis and characterization of carbon nanotubes and nano wires, Feynman Prize in Nanotechnology was awarded
2002 Feynman Prize in Nanotechnology was awarded for using DNA to enable the self-assembly of new structures and for advancing our ability to model molecular machine systems.
2003 Feynman Prize in Nanotechnology was awarded for modeling the molecular and electronic structures of new materials and for integrating single molecule biological motors with nano-scale silicon devices.
2004 First policy conference on advanced nanotech was held. First center for nano mechanical systems was established, Feynman Prize in Nanotechnology was warded for designing stable protein structures and for constructing a novel enzyme with an altered function.
2005-2010 3D Nano systems like robotics, 3D networking and active nano products that change their state during use were prepared.
2011 Era of molecular nano technology started
