The air filters with high Bacterial Filtration Efficiency (BFE) should help protect people effectively against various air borne particles including bacteria. In general, antibacterial properties of nanofiber membranes are tested by the conventional agar diffusion test where the small piece of test specimen is placed on agar plate and inoculated with test microorganism and incubated. This metho...
