New nanotechnology patents filed by Indian Institute of Technology, Madras
18 March 2009Nanotechnology is one of the forefront areas of research at premiere institutes worldwide and in Indian Institute of Technology, Madras also major work has been carried out in this area. The Indian premier research institute has recently been filed two new patents on nanotechnology applications and one patent is for better cancer drug delivery application and another is for removal of dyes from waste textile mill water.
The cancer drug delivery application of nanotechnology was carried out under the supervision of Dr. S. Ramaprabhu and his team found that by eliminating the use of a spacer, the drug delivery efficiency could be increased. His team joined the drug molecule directly to the carbon nanotube, which acts as a vessel for the drug molecule and directly transported to the CNTs containing drug molecule to the site. This resulted in reduced side effects, which would have otherwise been caused by the chemotherapy agents.
In the other invention, Professor Ramaprabhu and his team took nanomaterial as absorbent for removing the dyes from the wastewater generated by textile mill. It not only removes dyes but it also removes the bad odor from the water and makes the water suitable for use in industrial or agricultural applications.
Professor Ramaprabhu, took graphite in bulk with selected amount of carbon nanotube as adsorbent for cleaning the wastewater from textile industries. The team is also working on the wastewater from tanneries. Although it is possible to recover dyes from wastewater if the carbon nanotube is passed through a selected fluid, where the dye will be solubilized and it can later be recovered from the fluid.Â
