 Meeting ID: 961 6140 3733   Passcode: 569336My 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).  Minden érdeklődőt szívesen
