Figure Lengend Snippet: Inactivation of FCV by UV-C at 254 nm on ( A ) Stainless-steel; ( B ) Ceramic; and ( C ) Glass surfaces. Corresponding Linear 1D 10 -values for FCV on stainless-steel = 3.65 mJ/cm 2 ; Linear 2D 10 = 7.3 mJ/cm 2 ; Linear 3D 10 = 10.95 mJ/cm 2 ; Linear 1D-values for FCV on ceramic = 5.92 mJ/cm 2 ; Linear 2D = 11.85 mJ/cm 2 ; Linear 3D = 17.78 mJ/cm 2 ; and Linear 1D 10 -values for FCV on glass surfaces = 4.69 mJ/cm 2 ; Linear 2D = 9.38 mJ/cm 2 ; Linear 3D = 14.06 mJ/cm 2 .
Article Snippet: Similar to UV-C LED treatments of viruses, sterile stainless-steel and ceramic coupons or glass discs were placed within sterile petri dishes within a biosafety hood (254 nm, Labconco Purifier Class II Biosafety cabinet, 36208 020421542 A, Kansas City, MO, USA) for surface decontamination using 254 nm UV-C light for 10 min and 100 µL of either HAV (~5.5 log PFU/mL) or FCV (~6.0 log PFU/mL) were spread on stainless-steel or ceramic discs or 50 μL of each virus were aseptically spread on glass discs and allowed to dry within the biosafety hood for 10 min for the coupons and overnight for the discs (at an ambient temperature of 23 °C and 43% relative humidity).
