Holocellulose (73.04%) extracted from corn cobs as obtained from corn fields of Dehradun, Uttrakhand, was used for the preparation of nanoparticles ( ̴ 25 to 100 nm). In order to prepare the nanoparticles, we carried out the chemical treatment at different conditions by varying time, temperature and chemical compositions. The lignified product obtained at optimum condition was delignified by NaClO2/CH3COOH. The white powder product was further analyzed by Transmission Electron Microscopy (TEM). The size of nanoparticles ranged from 25 to 100 nm in lignified (brown powder) and delignified (white powder) product. The nanoparticles generated can be used as nanometric carriers to deliver the drug or biomolecules. The nanometric carriers have hydrophilic groups which could form non-covalent bonds with biological tissue forming bioadhesion may well extend the residence time and therefore increase the absorbance of loaded drug.

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
