title: Photonic Crystal Microbubbles as Suspension Barcodes.
abstract: A novel suspension array was developed that uses photonic crystal (PhC) microbubbles as barcode particles. The PhC microbubbles have an outer transparent polymeric shell, a middle PhC shell, and an inner bubble core, and they were achieved by extraction-derived self-assembly of colloidal nanoparticles in semipermeable solid microcapsules. The encoded elements of the microbubbles originated from their PhC structure with a coated shell, which not only improved the stability of the codes but also provided a flexible surface for bioassays. By using multicompartmental microcapsule templates, PhC microbubbles with substantial coding levels and controllable movement could also be achieved. In addition, as the size of the encapsulated bubbles could be tailored, the overall density of the PhC microbubbles could be adjusted to match the density of a detection solution and to remain in suspension. These remarkable properties make the PhC microbubbles excellent barcode particles.
