Nanotechnology: Design for the Future of Drug Delivery

Drug Delivery with Nanotechnology:

Nanotechnology has completed his fifty years on December 29, 2009. Professor Richard P.Feynman (Nobel Laureate, 1965) was the first person to predict and discussed the concept of nanotechnology. His prediction, to a large extent, has been realized till today. He on December 29, 1959 at an American Physical Society meeting at Caltech presented a celebrated talk ‘There’s plenty of room at the bottom,’ which represents the era of nanotechnology — the technology catering only nanometre scaled objects. The term Nanotechnology came into existence in the year 1974, by the help of Professor Norio Taniguchi.

Feynman research and development activity was pointing towards a new era of technology by aggregating things atom by atom, at present terms, ‘molecular nanotechnology’. He also discussed about writing the entire Encyclopaedia Britannica on the tip of a needle; also forecasted that one day the entire information of the world could be contained in an envelope! He also predicted that nanotechnologically developed little motors could be able to move within our blood vessels and do surgeries, duplicating the virtual surgeon. Now! To a large extent the predictions of Feynman, have been realized today.

Feynman added, “The principles of physics, as far as I can see, do not speak against the possibility of manoeuvring things atom by atom.” A new methodology to see and place atoms called scanning tunnelling microscopy came into existence in the year 1981 and numerous adjustments of this tool revolutionized all branches of science.
