The use of nanotechnology for nanobacteria (or calcifying nanoparticles) treatment is a new creative approach. Use of selenium nanoparticles (SeNPs) as anti-nanobacterial agents might be considered as a bright promising approach due to their critical role in the inhibition of crystal growth and aggregation of calcium oxalate. Hence, in this study, we investigated the probable outcome of SeNPs inhibitory effects on growth of nanobacteria. Fragments of thirty urinary tract stones were chemically analyzed by X-ray diffraction (XRD) and urinary stones Kits for calcifying nanoparticles presence. Then powder of stone fragments were resuspended in Dulbecco’s modified Eagle's medium (DMEM), sterilized by filtration and cultured in presence of 1, 5, 30, 60, and 90 µmol/L SeNPs concentrations. Besides, calcifying nanoparticles growth in the culture without SeNPs was measured spectrophotometrically. Also, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses were used, where calcifying nanoparticles formation occurred. Results showed that in the culture without SeNPs, the positive calcifying nanoparticles detection was 60% while after adding SeNPs at 90 µmol/L, not any calcifying nanoparticles were observed. Further confirmation came out when Energy-dispersive X-ray (EDX) analysis showed calcium and phosphate peaks in the culture medium without any SeNPs while in the culture containing 90 µm/L SeNPs a decrease in calcium and other minerals was obvious. Therefore, SeNPs clearly restricted the growth of nanobacteria due to their inhibitory effects on calcium oxalate deposition.
