| In the 1960's, Richard Feynman began manipulating molecules. Manipulating molecules resulted in Feynman's understanding of atomic composition, size and shape. In addition, Feynman noted how various molecular properties could change. In the beginning Fenyman wished to invent nanomachines in order to build complex products. His goal was for others to create superior materials at a low cost. This is now known as molecular manufacturing (MNT). Feynman, along with other chemists, could later identify the arrangement of atoms and the arrangement of molecules (molecular recognition). These chemists constructed mixed molecules, which were able to form superior solutions. However, there is some doubt that Richard Feynman was the first to enter the nanofield. Many believe that in 1974, while researching at the University of Tokyo, Norio Taniguchi was the first to develop the concept of nanotechnology and conducted work at the nanoscale. Others feel that nanotechnology began back in medieval times by glass workers. Whether or not Fenyman was the first to achieve success in the field of nanotechnology, the present day award in the field of nanoscience is known as "The Feynman." | ||||||||||||||||||||||||||||

| In 1981, a new team of researchers entered the nanofield. Led by Eric Drexler, chemists were now able to identify and describe the principles/properties of molecular engineering. Drexler was now manipulating molecules based on their respective positive and negative charges. Influenced by biology's Human Genome Project, Drexler began to map the newly arranged molecules from their work in nanoscience. Also at this time, Drexler realized that the newly manipulated molecules needed heat to obtain their structures. | ||||||||||||||||||||||||||||

| Time progressed and in 1991 the carbon nanotube was created through nanotechnology by an electron microscopist, Sumio Iijima. This was and is very significant due to the fact that the nanotube is greatly improving the commercial world in addition to the science world. The carbon nanotubes were then mass-produced in bulk quanities by Iijima's partners, Thomas Ebbesen and Pulickel Ajayan.
