You're right on the nano sector in general. It is not hot. Hot money are chasing oil and biofuel. But I think NANO sector especially the ones have already making a product shall succeed.
I think this INTK company is for real. They sell the products on their website, they also have an international distributor kit (agreement), I might want to have my Chinese friends to take a look at it, possible as a secondary income.
Again, the issue is with its patent. I cannot locate a patent under its company name.
