In this study, PCL/PVP/CuO nanofibrous mats for antibacterial applications were fabricated by electrospinning technique using PCL/PVP as a biopolymer matrix and copper oxide nanoparticles (CuONPs) as antimicrobial agents. PCL/PVP/CuO nanofibrous mats were successfully produced by doping different ratios of CuONPs (0.5%, 1%, and 2% wt) into the PCL/PVP solution. The chemical, morphological, and wetting properties of the prepared composite nanofibrous mats were evaluated by FT-IR, FE-SEM analysis, and water contact angle measurements. The morphological investigation indicated that the fiber diameters of the resulting nanofibers decreased as the CuONP content added to the PCL/PVP matrix increased, and the mean fiber diameter value measured for the PCL/PVP/2%CuONPs nanofibrous sample was 186.73. Moreover, wetting behavior of nanofiber surfaces displayed that the incorporation of PVP significantly enhanced the surface wettability of PCL with hydrophobic properties, but the addition of CuONPs to the obtained PCL/PVP matrix decreased it. An in vitro bactericidal assay was performed to investigate the efficacy of PCL/PVP/CuO nanofibrous samples against Staphylococcus aureus. The addition of CuONPs to the fibers led to antibacterial activity, which was found to increase with higher doping ratios. The results showed the potential of PCL/PVP/CuO nanofibrous mats to serve as an effective biomaterial for antibacterial applications.
In this study, the infrastructure of Necmettin Erbakan University Science and Technology Research and Application Center (BITAM) was used.

Bu çalışmada, biyopolimer matris olarak PCL/PVP ve antimikrobiyal ajan olarak bakır oksit nanopartikülleri (CuONPs) kullanılarak elektroçekim tekniği ile antibakteriyel uygulamalar için PCL/PVP/CuO nanolifli matlar üretildi. PCL/PVP/CuO nanolifli matlar, PCL/PVP çözeltisine farklı oranlarda CuONPs’in (ağırlıkça %0,5, %1 ve %2) katkılanmasıyla başarılı bir şekilde üretildi. Hazırlanan kompozit nanolifli matların kimyasal, morfolojik ve ıslanma özellikleri FT-IR, FE-SEM analizleri ve temas açısı ölçümü ile değerlendirildi. Morfolojik inceleme, PCL/PVP matrisine eklenen CuONPs içeriği arttıkça sonuçlanan nanoliflerin lif çaplarının azaldığını ve PCL/PVP/2%CuONPs nanolifli örneği için ölçülen ortalama lif çapı değerinin 186.73o olduğunu gösterdi. Dahası, nanolif yüzeylerinin ıslanma davranışı, PVP'nin dahil edilmesinin, hidrofobik özelliklere sahip PCL'ın yüzey ıslanabilirliğini önemli ölçüde arttırırken ancak elde edilen PCL/PVP matrise CuONPs ilavesinin ise azalttığını gösterdi. PCL/PVP/CuO nanoliflli örneklerinin Staphylococcus aureus'a karşı etkinliğini araştırmak için bir in vitro antibakteriyel aktivite testi gerçekleştirildi. CuONPs’ın liflere eklenmesi antibakteriyel aktiviteye yol açtı ve bu aktivitenin daha yüksek nanopartikül katkılanma oranlarıyla arttığı bulundu. Sonuçlar, PCL/PVP/CuO nanolifli matların antibakteriyel uygulamalar için etkili bir biyomalzeme olarak işlev görebilme potansiyelini gösterdi.
