COIMBATORE: The current age is characterised by innovative technological development and nano technology is advancing at an extraordinary pace. At present nano technology extends several hundred different commercial applications, B. Viswanathan, Vice-Chancellor, Sri Chandrasekharendra Saraswathi Viswa Mahavidyalaya University, Kanchipuram, said here on Wednesday.

Delivering the G.R. Damodaran Endowment Lecture on “Nano-science and Technology – A Journey into the Big World of Small Things” at the G.R. Damodaran College of Science, he said the National Science Foundation of the United States predicted that nano-related products and consumer services could be a $ 1 trillion market by 2015.

“In the Indian scenario, the Department of Science and Technology (DST), Government of India, has launched a nano-mission initiative in 2007 with more than 300 students engaged in nano-science research, 10 joint projects funded by the DST and three nano-science institutes are on the anvil,” Mr. Viswanathan said.

Pointing out the various applications that nano materials have found, for instance in catalysts, cosmetics, surface coatings and paints, food packaging, disinfectants, bandages, vapour sensors, etc., he said that many nano-particles were being used in various applications because bio-molecular and metallic components.

“Medical applications of nano-biotechnology are termed as nano-medicine.

A futuristic proposal is for a molecular positional device in nano-surgery.

Disease and illness are caused largely by damage at the molecular and cellular level.

Tools that are molecular both in size and precision with a computer to guide these tools are required to combat them.
