The demonstration of an UCNPs based nanosensor for the rapid and sensitive detection of OPs nerve agents. The ratiometric “turn-on” upconversion fluorescence observed by naked eyes in the presence of OPs nerve agents. The fabrication of an interesting paper-based device for the visualized POC assay of OPs nerve agents. The application of paper-based devices for the long-term monitoring of OPs nerve agents.
