Cavity-enhanced radiative energy transfer converts biomolecular information from a single droplet into trillions of distinctive photonic barcodes — ScienceDaily

Optical barcodes enable detection and tracking via unique spectral fingerprints. They’ve been widely applied in areas ranging from multiplexed bioassays and cell tagging to anticounterfeiting and security. Yu-Cheng Chen of the Bio+Intelligent Photonics Laboratory at Nanyang Technological University notes that the concept of optical barcodes typically refers to a fixed spectral pattern corresponding to a […]
