Fig. 3. (a) Capture abilities of Au@MNP-WGA for three target bacteria in aqueous solution with different pH values. (b) Capture efficiency of Au@MNP-WGA versus incubation time. (c) Capture ability of Au@MNP-WGA in PBS and three different sugar solutions. (d) Raman intensities of the Au@MNP-WGA-based LFA strip for L. mono detection at varying pH values. (e) Digital photograph and (f) corresponding Raman intensity at 1331 cm−1 of the proposed LFA for bacteria detection in different sugar solutions. The error bars represent the standard deviations from five measurements.
