MIT and Lincoln Lab researchers have developed microparticles that could be used to tag authentic products and help prevent counterfeiting. The particles are visible only when exposed to near-infrared light. Image: Jiseok Lee
The microparticles can be imaged and analyzed using a smartphone equipped with a special magnifying lens. Image: Jiseok Lee
