dc.description.abstractIn this study, 20-100 nm Au and Ag noble metal nanoparticles were produced using the Pulse Laser Deposition technique, and very sensitive optical properties of nanoparticles were investigated using the LSPR technique. The morphology of the produced nanoparticles was determined and characterized using scanning electron microscopy (SEM). The chemical bond structure of the Biotin molecule was investigated by Fourier Transform Infrared Spectroscopy (FTIR). In addition, the UV-Vis spectroscopy technique was used to determine LSPR absorption peaks of nanoparticles. Au and Ag Nanoparticles were deposited on the glass substrate depending on the laser deposition times. As the laser deposition time of the produced nanoparticles increased, both the size of the formed nanoparticles and the number of nanoparticles per unit surface increased. It was observed that the shape of Au and Ag nanoparticles produced based on SEM images was spherical. When UV-Vis spectra of Au and Ag nanoparticles were examined, it was observed that LSPR peaks shifted to longer wavelengths (redshift) as the laser deposition times increased. We have observed, to our knowledge, that the highest LSPR peak appeared at 1065 nm in the near-infrared region for plasmonic Au nanoparticles produced by Pulsed Laser Deposition. Once LSPR peaks of the plasmonic nanoparticles were characterized, Biotin molecules with different concentrations were attached to Ag and Au NPs to detect the sensor properties. LSPR peak shifts of bound nanoparticles could be observed and a blueshift of peaks was demonstrated as the concentration increased.en_US
