An assay for quantification of riboflavin (Rf) in milk-based products has been developed using the principle of surface plasmon resonance with on-chip measurement. The quantification was done indirectly by measuring excess of Rf binding protein (RBP) that remains free after complexation with Rf molecules originally present in the sample solution. The chip was modified with covalently immobilized Rf

report a templated reaction for the facile translation of nucleicacid cues into signals of universal rhodamine derivatives based on the riboflavin-catalyzed oxidation of dihydrorhodamines. The rhodamine-signaling operation allowed us to design a highly sequence-selective fluorescent sensor detecting as little as 500 pM of target nucleicacid in 90 min or to present a rhodamine antibody that can be
