다국어 초록 (Multilingual Abstract)

<P><B>Abstract</B></P> <P>In the present study, Ag nanoparticles decorated Mn<SUB>2</SUB>O<SUB>3</SUB> hybrid nanofibers were fabricated by calcination of electrospun PVP/AgNO<SUB>3</SUB>/Mn(NO<SUB>3</SUB>)<SUB>2</SUB> precursor nanofibers and characterized by FESEM, EDS, XRD, TEM. It was found that the prepared hybrid nanofibers included tiny Ag nanoparticles (from several to 15 nm) distributed uniformly in the Mn<SUB>2</SUB>O<SUB>3</SUB> matrix. The investigation of bactericidal activity towards gram-positive and gram-negative bacteria showed that Ag/Mn<SUB>2</SUB>O<SUB>3</SUB> hybrid nanofibers could exhibit enhanced efficiency than that of bare Mn<SUB>2</SUB>O<SUB>3</SUB> nanofibers. Therefore, this result suggests that the as prepared Ag/Mn<SUB>2</SUB>O<SUB>3</SUB> hybrid nanofibers can be a promising nanomaterial as a good alternative for the development of new bactericides.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Good morphology Ag/Mn<SUB>2</SUB>O<SUB>3</SUB> hybrid NFs were fabricated by electrospinning. </LI> <LI> Calcination of Ag<SUP>+</SUP>/Mn<SUP>2+</SUP>/PVP NFs gave pure crystalline hybrid NFs confirmed by XRD. </LI> <LI> TEM analysis revealed the uniform distribution of Ag NPs (∼15 nm) on Mn<SUB>2</SUB>O<SUB>3</SUB> matrix. </LI> <LI> Incorporation of Ag NPs could enhance the antibacterial activity of Mn<SUB>2</SUB>O<SUB>3</SUB>. </LI> <LI> Ag/Mn<SUB>2</SUB>O<SUB>3</SUB> hybrid NFs show promising prospects as new bactericide. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
