Fig. 10From: Label-free biosensing of Salmonella enterica serovars at single-cell levelThe SPR data obtained under five S. typhimurium concentrations. The aptamer APT33 was used as the probe molecule on CD-modified Au(111) surface. The concentrations for S. typhimurium are 1: 7.1 × 104 CFU mL−1, 2: 7.6 × 106 CFU mL−1, 3: 7.6 × 107 CFU mL−1, 4: 2.4 × 108 CFU mL−1, and 5: 2.4 × 109 CFU mL−1 Back to article page
