There is a debate to define which company may be considered a « Nanotechnology » company or not. It seems that a part of our audience expect to find molecular manufacturing companies with self-assembling robots capabilities. Some are considering the “bottom up” technology process of molecular manufacturing as the only “TRUE” nanotechnology. The problem is that as of writing this note, there are no “TRUE” nanotechnology companies according to the above definition. Thus we made the deliberate choice to list on Nanovip.com, companies involved in nanoscale interaction, manipulation, observation and fabrication: the result might not fit anyone’s expectation from a “nanotechnology company”.
It is easier to define the recent self-called nanotechnology start-ups, but it is more difficult to define already existing companies that are progressively incorporating nanoscale technology into their operations, yet these companies are still, in our opinion, engaged in the path of nanotechnology - a technology interacting with the matter at the nanoscale (atomic / molecular) level.

In this list of public nanotechnology companies' stocks, you will find both recent “nanotechnology” start-ups and established companies with various level of involvement in nanoscale technology.
It is up to you to decide if a company’s involvement in nanotechnology is enough to match your criteria as a nanotechnology stock investor.
