The present invention relates to a universal portable disinfectant chamber against wide spectrum microorganisms for sterilizing personal belongings. The chamber contains two UVC lights for 360° exposure of ultraviolet light to the subject enabling complete sterilization of all surfaces. The spherical cavity inside the chamber and reflective aluminum coating allows uniform and quick exposure on all surfaces. The chamber also has metal oxide nanoparticles based antiviral/antibacterial coating inside the spherical cavity to make sure that microorganisms do not sustain in the surface when the UVC light is not operating. The chamber is fully sealed, weighing less than 5kg and can be easily moved. A touch screen panel with Arduino based programming help to control the exposure time of UVC depending on the substrate making it possible to sterilize all kinds of belongings.

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.
