How is it different than the infection resistant surfaces we already have? Say microban which is found on most shopping carts as an example.

From a technology standpoint: they are a chemical additive, we are a nanotextured surface. Microban (Triclosan) can only prevent the bacteria from growing, we prevent the bacteria from adhering.

From a business standpoint: they don't own the product supply chain, they simply provide one component to existing chains. Nice for getting to revenue but not for big growth. We make (or intend too) the entire product, an application that is anti-microbial and can be placed on any existing surface, and for polymer based products we'll nanotexture those ourselves.
