Pocket-size gadget can detect counterfeit Viagra

The Stratio LinkSquare is small spectrometer that connects to a smartphone. This video shows the reflected light spectrum of three pills - a "fraud" Viagra pill, a generic pill, and the real thing compared to a genuine Viagra spectrum reference.

Stratio will crowdfund the LinkSquare this year and it will sell for $200.

Stratio says it eventually plans to branch out beyond pills to testing other items that can be mislabeled, like food (fish, for instance), and thinks it could be useful for consumers and companies, too.

Were hoping people can use this to assuage some of their fears about the things they consume, says Leslie Grothaus, a Stratio cofounder and its head of business development and communications.
