Synonyms: Methacryloyloxy fluorescein
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) .

3-Carboxyphenylboronic acid is a biochemical reagent with multiple functions including nanoparticle enhancement, perovskite passivation, fluorescence quenching, and adhesion. 3-Carboxyphenylboronic acid improves tumor penetration and pulmonary retention of nanoparticles, and serves as a tumor-targeting ligand for carboxymethyl chitosan nanoparticles. 3-Carboxyphenylboronic acid optimizes film crystallization via coordinate chelation of free lead/iodide ions in perovskites. 3-Carboxyphenylboronic acid acts as an additive for n-i-p perovskite solar cells. Conjugation of 3-Carboxyphenylboronic acid with PPEG8 quenches the near-infrared fluorescence of single-walled carbon nanotubes, enabling aqueous dispersion of carbon nanotubes through binding to the diol structure of saccharides .

DC271 is a RAR agonist and synthetic retinoid that binds to the retinoid-binding site of cellular retinoic acid-binding protein II (CRBP-II). DC271 exhibits solvatochromic fluorescence properties: it produces intense blue-shifted emission in nonpolar environments and weak red-shifted emission in polar environments, and its severe fluorescence quenching in aqueous solutions can be reversed by embedding in the hydrophobic retinoid-binding protein pocket. DC271 enables direct detection of the binding between unlabeled compounds and related retinoid-binding proteins via fluorescence competition assays (Ex/Em = 355 nm/460 nm) .
