“…In our previous study, PVA/PAA nanofibers showed relatively weak antibacterial activity against both E. coli and S. aureus, and by incorporating BN nanoparticles, the antibacterial activity was enhanced. 40 A further improvement in antibacterial activity was achieved with implementation of the MOs. The functional groups on the MOs, originating from both BN modification and reduction by the S. rebaudiana extract, enhance the ability of nanoparticles to bind to the bacterial cell membrane.…”

“…The antibacterial activity of fBN/MO-modified composite nanofibers was determined using Streptococcus mutans, Acinetobacter baumannii, Staphylococcus aureus, and Escherichia coli bacteria according to the previously published protocol. 40 The antioxidant activity of PVA/PAA and fBN/MO-modified composite nanofibers was determined using 2,2-azino-bis-3-ethylbenzothiazoline-p-sulfonic acid (ABTS). Potassium persulfate (K 2 S 2 O 8 , 2.45 mM) was added to the ABTS (7 mM, 3 mL) solution, stirred for 2 h, and then left in the dark for 12−16 h at room temperature for the generation of ABTS +• radicals.…”

CuO-, ZrO 2 -, and ZnO-immobilized functional boron nitride (fBN) nanoparticles were synthesized by an environmentally friendly approach using a Stevia rebaudiana extract. Metal-oxide-immobilized fBN nanoparticles (fBN/MO)-incorporated (1 wt %) polyvinyl alcohol/poly(acrylic acid) composite nanofibers were fabricated by electrospinning, and their antibacterial, antioxidant, and photocatalytic properties were investigated. fBN/CuO and fBN/ ZnO nanoparticles were distributed randomly, showcasing nonuniform geometries besides polygonal-shaped fBN/ZrO 2 nanoparticles. fBN/MO nanoparticles exhibited a uniform dispersion along the composite nanofibers, with diameters between 115 and 160 nm. The incorporation of fBN/MO nanoparticles into the composite nanofibers (0.074−0.753 W/mK) resulted in an improvement in both thermal stability and conductivity when compared with PVA/PAA nanofibers (0.063 W/mK). fBN/MO-modified composite nanofibers exhibited an antibacterial efficacy exceeding 99% against Streptococcus mutans, Acinetobacter baumannii, Escherichia coli, and Staphylococcus aureus, augmenting their antioxidant properties. The modified composite nanofibers, particularly those incorporating fBN/ZrO 2 nanoparticles, exhibited effective photocatalytic remediation against methylene blue (MB) with the highest activity, attributed to their favorable morphological and optoelectronic properties, resulting in a remarkably more than 20-fold improvement. Enhanced stability for repeated treatment of MB for a minimum of three cycles was achieved. The multifunctional nature of nanofibers unveils synergistic antibacterial, antioxidant, and photodegradation effects, positioning them as promising for biomaterials and water disinfection.
