Fig 1: Selectivity test: pollen-based nanoplasmonic biosensor response to IL-1β and IL-18 at 100 aM and to IL-17A at 5 aM. One-way ANOVA # p < 0.05 vs. IL-1β and * p < 0.05 vs. IL-18.
Fig 2: Comparison between the resonance wavelength variations obtained by testing the BC-based LSPR biochip with the interfering substances (IL-1β and IL-18) at 1 nM and the analyte target (IL-17A) at 1 fM.
