Fluorescein O-methacrylate
Based on 1 Customer Validation
Fluorescein O-methacrylate (Methacryloyloxy fluorescein) is a pH-responsive fluorescent monomeric dye. Fluorescein O-methacrylate exhibits pH-responsive fluorescence properties: its fluorescence is activated under alkaline conditions and quenched under neutral or acidic conditions; reversible switching of fluorescence is achievable by adjusting the pH of the solution. Fluorescein O-methacrylate can be used as a monomer for the synthesis of amphiphilic fluorescein polymers. These polymers can self-assemble into stable polymer nanoparticles with enhanced aqueous-phase fluorescence, and also enable the conjugation of nanoparticles with amine-containing biomolecules to support sensitive optical detection of biomarkers (Ex/Em = 490/520 nm).

Biological Activity
Fluorescein O-methacrylate (0.25-0.9 mol%; 25 h, 3 cycles) incorporated into PBPEM415-g-(PBA-co-PFMA)40 bottlebrushes confers pH-responsive fluorescence, with no emission at pH 6 or 7 and strong green emission at pH 8, 9, or 10, and this switching behavior is fully reversible across three cycles with minimal quenching[1].
Fluorescein O-methacrylate (0.2 mmol; 24 h polymerization) -containing amphiphilic copolymers (poly(FMA-r-NAS-r-MA)) self-assemble into stable, size-tunable spherical nanoparticles with enhanced fluorescence, and FPNP1 (incorporating 8% Fluorescein O-methacrylate (Methacryloyloxy fluorescein)) exhibits optimal dispersion stability and BSA immobilization efficiency, making it a suitable platform for optical biosensors[2].
