The ToC and Abstract graphic
and Figure 5 in the
original paper contain a mistake
in the biotin structure (the hydrogen atoms are missing). This error
has been corrected here in ToC/Abstract image and Figure 5. The text in the original
manuscript was correct and all reported results remain unchanged.
Figure 5.
Scheme of the FO-SPR setup and the steps involved in the click functionalization of the fibers (A). FO SPR spectra of a bare fiber, after PEDOT-N3 electropolymerization and click of the acetylene-PEG4-biotin (B). Kinetic experiment of the NeutrAvidin binding for the biotin-PEDOT-N3-FO (raw and smoothed data) (C). Transfer characteristics curves of a PEDOT-N3 OECT before, after the click reaction with acetylene-PEG4-biotin, and after NeutrAvidin recognition (VDS = −0.1 V, 1× PBS) (D) and threshold voltage obtained from the transfer curves (n = 3) (E). Recorded change in IDS of an HRP-streptavidin–biotin-PEDOT-N3-OECT (and control experiment without HRP) (left) and its dependence with the concentration of H2O2 (right) (VDS = −0.1 V, VG = 0 V, 1× PBS) (F).
