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.

The present disclosure provides new reagents for labeling and detecting O-glycans released from a glycoconjugate, such as a glycoprotein, glycopeptide, peptidoglycan, or proteoglycan of interest. O-glycans labeled with the labels can be detected by fluorescence, MS, and UV. The invention further provides methods for making the reagents, methods for using them, and kits comprising them. O-glycans labeled with the reagents can be analyzed by high-throughput analysis.
