This study presents the biogenic synthesis of zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles using ovalbumin, an abundant and non-toxic protein from egg white. The synthesis process was optimized by varying metal ion concentrations to control particle size and morphology. Characterization using ATR-FTIR, XRD, SEM, and UV-VIS confirmed the successful formation of uniform, well-crystallized nanoparticles with sizes ranging from 7.9 to 13.5 nm. ZnO nanoparticles exhibited superior antimicrobial efficacy against Escherichia coli and Enterococcus faecalis, while MgO nanoparticles showed enhanced potential environmental remediation. These findings highlight ovalbumin as a versatile agent for the green synthesis of ZnO and MgO nanomaterials, with promising applications in the medical, environmental, and optoelectronic fields. The results indicate that this biogenic method can serve as a sustainable proposal to produce nanostructured materials with diverse applications in the medical and environmental fields, such as eliminating pathogenic bacteria and purifying contaminated environments. Overall, this study significantly contributes to the development of sustainable nanomaterials and opens up new perspectives on the use of ovalbumin protein in the synthesis of multifunctional nanostructured materials.<\/jats:p>","DOI":"10.3390\/molecules30051164","type":"journal-article","created":{"date-parts":[[2025,3,5]],"date-time":"2025-03-05T03:18:22Z","timestamp":1741144702000},"page":"1164","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Ovalbumin-Mediated Biogenic Synthesis of ZnO and MgO Nanostructures: A Path Toward Green Nanotechnology"],"prefix":"10.3390","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8648-4402","authenticated-orcid":false,"given":"Adriana-Gabriela","family":"Schiopu","sequence":"first","affiliation":[{"name":"Faculty of Mechanics and Technology, Pitesti University Centre, National University of Science and Technology POLITEHNICA Bucharest, 110040 Pitesti, Romania"},{"name":"Doctoral School Materials Science and Engineering, National University of Science and Technology POLITEHNICA Bucharest, Splaiul Independentei no. 313, Sector 6, 060042 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena Andreea","family":"Vijan","sequence":"additional","affiliation":[{"name":"Doctoral School Materials Science and Engineering, National University of Science and Technology POLITEHNICA Bucharest, Splaiul Independentei no. 313, Sector 6, 060042 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ecaterina Magdalena","family":"Modan","sequence":"additional","affiliation":[{"name":"Regional Center of Research & Development for Materials, Processes and Innovative Products Dedicated to the Automotive Industry (CRCD-AUTO), Pitesti University Centre, National University of Science and Technology POLITEHNICA Bucharest, 110040 Pitesti, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sorin Georgian","family":"Moga","sequence":"additional","affiliation":[{"name":"Regional Center of Research & Development for Materials, Processes and Innovative Products Dedicated to the Automotive Industry (CRCD-AUTO), Pitesti University Centre, National University of Science and Technology POLITEHNICA Bucharest, 110040 Pitesti, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7525-1056","authenticated-orcid":false,"given":"Denis Aurelian","family":"Negrea","sequence":"additional","affiliation":[{"name":"Regional Center of Research & Development for Materials, Processes and Innovative Products Dedicated to the Automotive Industry (CRCD-AUTO), Pitesti University Centre, National University of Science and Technology POLITEHNICA Bucharest, 110040 Pitesti, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Istrate","sequence":"additional","affiliation":[{"name":"Doctoral School Materials Science and Engineering, National University of Science and Technology POLITEHNICA Bucharest, Splaiul Independentei no. 313, Sector 6, 060042 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgiana","family":"C\u00eerstea","sequence":"additional","affiliation":[{"name":"Regional Center of Research & Development for Materials, Processes and Innovative Products Dedicated to the Automotive Industry (CRCD-AUTO), Pitesti University Centre, National University of Science and Technology POLITEHNICA Bucharest, 110040 Pitesti, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0324-0846","authenticated-orcid":false,"given":"Mihai","family":"Oproescu","sequence":"additional","affiliation":[{"name":"Faculty of Electronics, Communication and Computers, Pitesti University Centre, National University of Science and Technology POLITEHNICA Bucharest, 110040 Pitesti, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u015eaban Hakan","family":"Atapek","sequence":"additional","affiliation":[{"name":"Department of Metallurgical and Materials Engineering, Kocaeli University, 41001 Kocaeli, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Mudalige, T., Qu, H., Van Haute, D., Ansar, S.M., Paredes, A., and Ingle, T.
