General description

Fluorescein o-acrylate is a fluorescent monomer with high quantum efficiency in aqueous media. Its excitation and emission wavelength are in the range of visible light. It can be copolymerized with a variety of monomers such as acrylic acid, styrene and acrylamide which facilitate the attachment of fluorescein with macromolecules.

Application

Fluorescein o-acrylate can be used in the formation of fluorescent probes for application in bio-imaging. It can also be used in the synthesis of molecularly imprinted polymers (MIPs). It also facilitates the demarcation of different layers in fluorescence microscopy.

Coacervate complexes that are liquid-liquid separated complex materials are often formed by stoichiometrically mixing oppositely charged polyelectrolytes in salted aqueous solution. Entropy-driven ion pairing, resulting from the release of counterions near polyelectrolytes, has been identified as the primary driving force
