Fluorescent compositions
| DWPI Title: Performing detection process involves combining material and substrate to form article, material comprises fluorescent sensor compound and organic reporter molecules encapsulating in microsphere structure, combining substrate |
| Abstract: An article that includes a fluorescent composition having at least one of a fluorescent sensor compound and organic reporter molecules encapsulated in a microsphere structure. When encapsulated, the fluorescent sensor compound and the organic reporter molecules are distributed in a liquid organic matrix. When non-encapsulated, the remaining one of the fluorescent sensor compound and the organic reporter molecules reside in the matrix. In response to a force applied to the composition sufficient to break at least a portion of the microsphere structure, the fluorescent sensor compound and the organic reporter molecules are transformed into a non-reversible fluorescent state exhibiting a quantum yield greater than 0.2. The fluorescent state is objectively visually verifiable without physically contacting the composition. |
| Use: Method for performing detection process. |
| Advantage: The method enables to perform detection process that provides improved permit flexibility. |
| Novelty: Performing detection process involves combining material and substrate to form article. The material comprises fluorescent sensor compound and organic reporter molecules encapsulated in microsphere structure, when encapsulated, fluorescent sensor compound and organic reporter molecules are distributed in liquid organic matrix, when non-encapsulated, remaining one of the fluorescent sensor compound and organic reporter molecules reside in the matrix, applying force to the material sufficient to break portion of the microsphere structure to transform fluorescent sensor compound and organic reporter molecules into non-reversible fluorescent state exhibiting quantum yield greater than 0.2. The fluorescent state is visually verified without physically contacting the material. |
