Impregnation of transparentmatrix polyvinyl alcohol and polyvinyl pyrrolidone nanocomposites was done by silver oxide and niobium oxidenanoparticles. The nanostructures were created using different ratios of polymer matrix, silver oxide nanoparticlesand niobium oxide nanoparticles. The optical features of these nanocomposites were examined, whereby the lattertype of properties was tested within the wavelength range of 220-820nm. The determination of the anti-microbialactivity was done by disc diffusion method. The anti-bacterial activity involved gram-positive and gram-negativeorganisms. Different bacteria were cultured with Muller-Hinton medium.Results: Absorbance, absorption coefficients and optical conductivity of the nanocomposites increased with theincrease in nanocomposite concentrations. The energy gap for silver oxide and niobium oxide nanoparticlesdecreased when the concentrations of the nanoparticles increased.Conclusion: Promising outcomes may be achieved for the nanocomposites in anti-bacterial applications as theinhibition zones increased along with increased ratio of silver oxide and niobium oxide nanoparticles.Key Words: Dissolver oxide, Polyvinyl Alcohol, Niobium, Polyvinyl, Nanocomposites, Nanoparticles, Pyrrolidinones<\/jats:p>","DOI":"10.47391\/jpma-bagh-16-48","type":"journal-article","created":{"date-parts":[[2024,10,8]],"date-time":"2024-10-08T14:18:01Z","timestamp":1728397081000},"page":"S214-S218","source":"Crossref","is-referenced-by-count":0,"title":["The influence of Ag2O\/NbO2 nanocomposites on the optical properties of PVA\/PVP lend in biomedical applications"],"prefix":"10.47391","volume":"74","author":[{"family":"Sroor Fadhil Obaid","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Raheem Kadhim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"26547","published-online":{"date-parts":[[2024,9,28]]},"container-title":["Journal of the Pakistan Medical Association"],"original-title":[],"link":[{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/download\/21857\/3661","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/download\/21857\/3661","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,10,11]],"date-time":"2024-10-11T14:18:01Z","timestamp":1728656281000},"score":1,"resource":{"primary":{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/view\/21857"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,9,28]]},"references-count":0,"journal-issue":{"issue":"10 (Supple-08)","published-online":{"date-parts":[[2024,9,28]]}},"URL":"https:\/\/doi.org\/10.47391\/jpma-bagh-16-48","relation":{},"ISSN":["0030-9982","0030-9982"],"issn-type":[{"type":"electronic","value":"0030-9982"},{"type":"print","value":"0030-9982"}],"subject":[],"published":{"date-parts":[[2024,9,28]]}}}
