TL;DR: A novel room-temperature-phosphorescence (RTP)-based oxygen detection platform by constructing core-shell nanoparticles with water-soluble polymethyloxazoline shells and oxygen-permeable polystyrene cores crosslinked with metal-free purely organic phosphors, which shows a very high sensitivity for DO.
Abstract: Highly sensitive optical detection of oxygen including dissolved oxygen (DO) is of great interest in various applications. We devised a novel room temperature phosphorescence (RTP) based oxygen detection platform by constructing core-shell nanoparticles with water-soluble polymethyloxazoline shells and oxygen-permeable polystyrene core crosslinked with metal-free purely organic phosphors. The resulting nanoparticles show a very high sensitivity (limit of detection (LOD) of 60nM DO) and can be readily used for oxygen quantification in aqueous environments as well as gaseous phase.

TL;DR: The CE-chip is able to determine a protein biological threat agent simulant, ovalbumin (Ov), by performing an immunoassay separation of Cy-5 labeled anti-ovalbumin from its complex with Ov, in under 30 s.
