I'm looking for someone to create a list of 25 nanotechnology-related
web sites that will likely swap links with another nanotechnology web
site.  The criteria for these potential linking partners is:

1. The sites must have their own domain name, not a free domain like Geocities
2. The sites cannot by government or educational web sites. 
Commercial is preferred.
3. The sites must have a links page that is linked to on their home
page, and the sites must have some sort of statement that they are
willing to swap links.
4.  The sites must be of good quality.  This is in the eye of the
beholder, but I want to avoid juvenile sites.  Basic is OK,
unprofessional is not.  Let me know if this needs clarification.

The list should include:
1. Website URL
2. URL of links page on that web site
3. Contact e-mail address for the web site

Any questions please let me know.
