Charge Transport Phenomena in Peptide Molecular Junctions
Figure 3
(a)
I/V properties of the molecular junctions containing the nonphosphorylated
test peptide (log scale, mean and standard errors); (b) density plot of I values (A) at 0.5 V for
the nonphosphorylated peptide, logarithmic
scale; (c)
I-V characteristics of the molecular junctions containing the phosphorylated
test peptide, logarithmic scale, mean and standard errors;
(d) density plot of I values (A) at 0.5 V, logarithmic scale; (e) five
separate I-V traces of a molecular junction containing the phosphopeptide; (f) a
comparison of the average I-V traces for plain (gray) and phosphorylated
(black) test peptides (Wilcoxon rank sum p < 0.0001017).
