Inorganic Compounds

Yttrium (III) fluoride is an inorganic chemical compound with the chemical formula YF3. These YF3 NP-modified catheters were investigated for their ability to restrict bacterial biofilm formation. The YF3 NP-coated catheters were able to significantly reduce bacterial colonization compared to the uncoated surface.

Yttrium (III) fluoride are well known for their antibacterial activity and act in multiple ways to affect the metabolism of bacteria application of nano-scale materials and structures is an emerging area of material science and nanotechnology. Continuing advances in nanotechnology promise to be of great benefit for a wide variety of applications including various medicinal uses, such as therapeutics, diagnostic, or drug delivery.

Yttrium Fluoride nanopowder  crystals are radiation detectors and efficient TL dosimeters mainly for higher energy radiation. Most solidstate dosimeters are based on effects of thermoluminescence and more recently also on methods of optically stimulated luminescence and photo-transferred.  It should also be noted that the application of monochromatic VUV radiation enables the evaluation of the photon energy which is most efficient for the formation of defects and the excitation of TL.

Antimicrobial activity of the Yttrium III fluoride nanopowder (YF3)  was examined on logarithmic phase cultures by using a modified macrodilution assay. overnight cultures of tested bacteria were diluted (1:100) in fresh TSB or TSB-Glu and grown for 4 hours at 37°C (shaking, 250 rpm) to allow the cells to reenter logarithmic phase.
