Fluorescein O-methacrylate is a pH-responsive fluorescent monomeric dye that exhibits fluorescence activation in alkaline environments and quenching in neutral or acidic conditions. This reversible fluorescence switching is achieved by manipulating the pH of the solution, making it a valuable tool in biological applications. As a monomer, it facilitates the synthesis of amphiphilic fluorescein polymers, which can self-assemble into stable polymer nanoparticles. These nanoparticles demonstrate enhanced fluorescence in aqueous phases and allow for the conjugation with amine-containing biomolecules, supporting sensitive optical detection of biomarkers (Ex/Em = 490/520 nm).
