Background/AimY2O3-Al2O3-SiO2 (YAS) glass microspheres are currently used in radioembolization treatment. However, abscess formation can occur following this treatment. This study aims to endow YAS glass microspheres with antibacterial properties to address the abscesses forming in patients after radioembolization treatment.Materials And MethodsIn this study, undoped YAS glass microspheres and those doped with antibacterial agents zinc (Zn) and/or copper (Cu) were successfully fabricated using a sol-gel derived method.ResultsAfter heat treatment, the microspheres exhibited an amorphous structure. Additionally, the incorporation of Zn and/or Cu dopants did not alter the patterns observed in the X-ray diffraction analysis. Fourier transform infrared spectroscopy analysis detected Si-O-Si, Al-O-Al, and Y-O band vibrations within the structure. The presence of Zn and Cu dopants was confirmed through X-ray photoelectron spectroscopy analysis. Scanning electron microscopy revealed that all samples possessed a regular microsphere morphology, with average particle sizes ranging from 6 to 50 μm. These average particle sizes were further confirmed using a mastersizer.ConclusionThe antibacterial agent-doped YAS glass microspheres show promise in combating infections that occur following radioembolization treatment.© TÜBİTAK.
