General description

Fluorescein O-methacrylate is a pH sensitive dye with a fluorescent monomer. It can be characterized by an excitation spectra at 490 nm and an emission spectra at 520 nm. It has fluorescein that acts as an indicator with the least negative charges. Its properties include biocompatibility, non-toxicity and good dispersion in aqueous solution.

Application

Fluorescein O-methacrylate can be used as a marker that can be incorporated into the nanoparticle complexes for biological applications. It forms environmentally responsive materials that can be used as probes for cellular imaging.

We compared the influence of the polymerization mechanism onto the physical characteristics of thermoresponsive hydrogels. The Poly(N-isopropylacrylamide) (PNIPAAm) hydrogels were successfully synthesized using reversible addition-fragmentation chain-transfer (RAFT) and free radical polymerization (FRP). The gels were prepared while using different crosslinker
