Nanonphase Technologies Corporation is a Quality Play

According to this article, NANX is a good nanotechnology stock:

Nanophase has an established customer base, including BASF (NYSE: BF),
which has signed a contract to get 75% of its nano-oxide requirements
for sunscreen products from Nanophase. We can and do argue that
Nanophase's customer base is too small, and that it must reduce its
reliance on BASF for real growth and development.

But at least we know Nanophase is not the one supplying inferior
products. The same applies to Carbon Nanotechnologies and Quantum Dot.
Despite being private, they, too, have an impressive list of clients to
take advantage of their patented products and processes.
