My doctoral work is aimed at the preparation and laser spectroscopic characterization of micron-sized polymeric microparticles for different applications.‎ First, I studied the polymerization kinetics of diethylene glycol dimethacrylate (DEGDMA) monomer in different solvents upon gamma irradiation with different doses. Then, fluorescent monodisperse DEGDMA microparticles were synthesized through the incorporation of fluorescein isothiocyanate isomer I (FITC) dye into the polymer matrix. In the last part of my study, I have developed a method to prepare substrates for surface-enhanced Raman scattering (SERS) by attaching gold nanoparticles to polymeric DEGDMA microparticles prepared by gamma radiation-initiated polymerization. The performance of the proposed SERS substrates was tested by the detection of DNA strands specific to the Giardia lamblia parasite (the β-giardin gene).
