When 20-something Krisanu Bandyopadhyay, armed with an MS degree from the University of Calcutta, first came to Pune in the mid-1990s to pursue his PhD at the National Chemical Laboratory (NCL), he was full of excitement and apprehensions. "For a Calcutta boy who had never stayed out of West Bengal, going to Pune to study was a major step," he recalls. His subsequent stint in Pune changed his life completely.
Today, Bandyopadhyay, an assistant professor of chemistry at the University of Michigan-Dearborn (UM-D), US, is a well-known specialist in nanotechnology. He recently introduced an undergraduate course in nanobiotechnology at UM-D. In lay terms, nanotechnology refers to the science and technology of building devices, such as electronic circuits, from single atoms and molecules. A multi-disciplinary field, it involves the control of matter on the molecular level in scales smaller than 1 micrometre — normally 1 to 100 nanometres — and the fabrication of devices within that size range. Nanobiotechnology applies the tools and processes of nano-fabrication to build devices for studying bio-systems.
