Electrospinning and antimicrobial properties of PAN-Cu₂O/ZnO nanofibers from green peel extracts

Abstract This study described the antimicrobial activities of waste biomass-mediated Cu 2 O/ZnO bi-oxide (BiO) nanocomposites; The Orange peels extract (OPE), and lemon (LPE), were used to synthesize bioxide nanoparticles (NPs) designated as OPE/BiONPs, LPE/BiONPs respectively, characterized with x-ray diffraction (XRD), zeta potential (ZP); average crystalline sizes computed 11.57 nm 13.36 for OPE/BiONPs respectively; potentials values −36.8 mV, −35.5 mV Polyacrylonitrile (PAN) polymer BiONPs blends electrospun into nanofibers get unblended PAN nanofiber (NF), OPE/BiO NF, LPE/BiO NF; Scanning electron microscopic (SEM) analysis was determine morphology NF possessed diameters 833 ± 125, 282.86 29, 558.76 81 examined their against five (5) pathogens public health significance comprising Gram-positive ( Bacillus cereus Enterococcus faecalis ) Gram-negative Salmonella enteritidis, Escherichia coli, Vibrio cholerae bacteria, using standard dilution microplate-method; synthesized nanomaterials showed various levels inhibitory target pathogens. NPs exhibited 98% inhibition growth at a concentration 810 μ g ml −1 , while 71% coli 243 . LPE/BiONF had 72% S. enteritidis MIC 2.7 mg CPE/BiONPs, NFCs could have comparative advantage commercial antibiotics hence be in control waterborne
