(a) Schematic illustration of a graphene oxide sensing platform for the detection S. typhimurium (Bacterial cells concentration can be detected by turning on the fluorescence signal after the aptamer is bind to target bacterial cells). (b) Schematic representation of the PDMS/paper hybrid microfluidic chips for one-step pathogenic bacteria detection. (c) Illustration of the pathogenic bacteria detection principle inside the microfluidic channels. Reproduced with permission from ref. 19. Copyright 2014, Springer-Verlag Wien and ref. 20.
