IIT-M files patent for 2 applications of nanotechnology

Abstract:
Continuing to remain at the forefront of using cutting-edge technology to meet societal needs, IIT-Madras is filing a patent on two new applications of nanotechnology for removal of dyes from waste water released from textile mills and for more efficient drug delivery in cancer treatment.

The small size of nanomaterials ensures the presence of many atoms or molecules near interfaces thereby leading to a very high surface area, said Dr S Ramaprabhu, professor, Alternative Energy and Nanotechnology Laboratory (AENL), department of physics. Pointing out that 1 gm of the material could extend over an area as vast as a football field, the professor said this made the nanocomposite adsorbent (substance sticks to the surface rather than being absorbed into the medium) ideal for removal of dye molecules when attached to proper functional groups.
