Abstract: The thermal and mechanical properties of nasopharyngeal airway (NPA) samples are improved by irradiation using 4keV oxygen and nitrogen ion beams with different ion fluences varying from 25×1017 ions/cm2 to 65×1017 ions/cm2. The thermal stability of NPA medical device increases with increasing nitrogen and oxygen ion fluences. The tensile strength increased from 48MPa for unirradiated sample to 74MPa for samples irradiated with nitrogen and to 58MPa for samples irradiated with oxygen ion, while the elongation at break decreases for irradiated samples. Silver thin films are deposited on NPA medical device samples using 4keV argon ion beam. The XRD spectra demonstrated that silver nanoparticles are deposited on NPA medical device substrate. The effects of Ag thin film on gram-positive and gram-negative bacteria are studied.
