Abstract

Co-polymerisation of α-styryl-poly(ethylene glycol)300, α,ω-bis(styryl)-penta(ethylene glycol) and 2,5-diphenyl-4-(4′-vinylbenzyl)oxazole in varying molar ratios resulted in the production of chemically functionalised scintillant-containing poly(oxyethylene glycol) polymer (POP-Sc) supports. These materials are compatible with both aqueous and organic solvents, and possess the ability to scintillate efficiently in the presence of ionising radiation, even after prolonged and repeated exposure to organic solvents. The utility of POP-Sc supports in both solid-phase peptide chemistry and a functional scintillation proximity assay has been exemplified.

Abstract

The first demonstration of the use of functionalised polystyrene beads as “polymeric ligands” for the immobilisation of quantum dots (QDs) is presented. Specifically, thiol-containing polystyrene microspheres were synthesised and used to incorporate QDs viaa swelling/doping strategy. The resultant composite materials were shown to be highly stable against QD leaching in both apolar and polar solvents and retained an identical QD emission profile to non-immobilised QDs. This straightforward approach also allows easy access to controllable and reproducible multiple-QD-containing microspheres. [ABSTRACT FROM AUTHOR]
