Graphene Alternatives & Detecting Explosives - LIGHT MATTERS 05.14.2014

On this week’s show, nanocrystal tags aid in pathogen detection, researchers probe graphene alternatives, a fiber sensor detects explosives, and we share some highlights from this year’s SPIE DSS conference. Light Matters is the photonics industry’s only weekly news program and is hosted by Photonics Media editors Laura Marshall and James Lowe.
