(A) Inhibition zone images against Staphylococcus aureus (top row) and Escherichia coli (bottom row) of the as-prepared PVA (i), PVA-Ag (ii), PVA-Ag@heat (iii), PVA-Ag@UV (iv) nanofibrous mats, respectively. (B) Antimicrobial kinetic tests for electrospun samples as a function of incubation time against S. aureus.

Notes: The inset has real-time pictures of the numbers of colonies on agar plates with different samples after 30 minutes contact. The fractional survival was calculated as FS = N/N₀ (where N is the number of surviving bacterial colonies in each sample after certain contact time period and N₀ is the original bacterial suspension at zero point of the time scale).

Abbreviations: PVA, poly(vinyl alcohol); PVA-Ag, AgNPs-containing nanofiber mats; PVA-Ag@heat, PVA-Ag on preheating conditions; PVA-Ag@UV, PVA-Ag sample irradiated under UV lamp; FS, fractional survival; S. aureus, Staphylococcus aureus; E. coli, Escherichia coli; min, minutes.
