Electron spin resonance (ESR) spectroscopy together with spin trapping techniques and the application of state-of-the-art loop gap resonators was used to provide a direct measure of spontaneous oxygen radical production by homogenates of freshly isolated and cultured rat pancreatic islets. Using the spin trap agent, 5,5-dimethyl-1-pyrroline-N-oxide (DMPO),(More)
Gum Arabic (GA) microgels were successfully prepared via reverse micellization method with high yield (78.5±5.0%) in 5-100μm size range using divinyl sulfone (DVS) as a crosslinker. The GA microgels were degraded hydrolytically 22.8±3.5% at pH 1 in 20days, whereas no degradation was observed at pH 7.4 and pH 9 at 37°C. By using diethylenetriamine (DETA),(More)
This study aims to establish a facile protocol for the preparation of a bi-layered poly(glycerol-sebacate) (PGS)/β-tricalcium phosphate (β-TCP) construct and to investigate its potential for bone-soft tissue engineering applications. The layered structure was prepared by distributing the ceramic particles within a prepolymer synthesized in a microwave(More)
A novel resourceful bulk poly(Tannic Acid) (p(TA)) hydrogel was prepared by crosslinking TA molecules with an epoxy crosslinker, trimethylolpropane triglycidyl ether (TMPGDE), in an autoclave at 90°C for 2h. The obtained p(TA) hydrogels were in disk form and have highly porous morphology. The swelling characteristics of p(TA) hydrogels were investigated in(More)
This work presents a new approach to fabrication and characterization of novel polymer nanofiber electrolytes from intercalated PVA/ODA-MMT nanocomposite as a matrix polymer and encapsulated graphene oxide (GO) nanosheets with amphiphilic reactive copolymer as partner polymers using electrospinning method. The chemical and physical structures, surface(More)
A novel carboxyl-trithiocarbonate functionalized polymer with a highly selective antitumor activity was synthesized by a reversible addition-fragmentation chain transfer (RAFT) polymerization of maleic anhydride (MA) with benzoyl peroxide as an initiator and S-1-dodecyl-S-(α,α'-dimethyl-α"-acetic acid)trithiocarbonate as a RAFT agent with the aim to design(More)
Crosslinked p(sucrose) micro particles were synthesized for the first time from sucrose in water-in-oil microemulsion. Using divinyl sulfone (DVS) as crosslinker via reverse micelles of sodium bis(2-ethylhexyl) sulfosuccinate (AOT) p(sucrose) micro particles formed in a single step with very high yield (>90%). The particles have wide size distributions, and(More)
