Paper-based platforms for biofilm studies. A digital photograph of the arrays fabricated on a) Kaolin coated paper and b) latex coated paper. A schematic illustration of the reaction array platform c). Optical micrograph of an unexposed reaction area on Latex 2 substrate d). Optical micrograph of the reaction array fabricated on Latex 2 after exposure to e) S. aureus (18 h), f) S. aureus for 5 min followed by incubation in TSB for 18 hours, and g) S. aureus (18 h) followed by exposure to K2 (24 h). Diameters of the reaction areas are 2 mm in d, and 5 mm in others. The scale bar is 1 mm.
