Nanotechnology is a vast field with people working on it all around the world. According to ones expertise one can really provide information on a webiste so that particular person working on particular topic can search and understand the depth of the science behind it. Idea is gud but it needs time for processing it. Like it should be something like wikipedia. Good idea.. Good luck...
Take a look at the Primers page on the nanoparticles.org site:
