Self-assembled peptides have many applications within the biomedical field and in nanoelectronics due to their biocompatibility and the ease to synthesize various chemical functionalities into the peptides. The self-assembly process can result in the formation of different nanostructures, as well as macroscopic structures, with a range of applications. While many applications for self-assembling peptides have been found, more characterization of the properties of these self-assembling peptides is still needed. Our research looks at the gs-GKFF-OH and gs-GKFF-NH<sub>2 </sub>self-assembling nucleopeptides, in which guanosine (gs) has been added to a short self-assembling peptide, to investigate whether differences in structure cause different levels of conductivity. In a previous report, these two nucleopeptides assembled into different supramolecular structures, with the gs-GKFF-OH forming short, twisting nanofibers with an average width of 4 nm and the gs-GKFF-NH<sub>2</sub> nucleopeptide assembling into uniform, flat nanosheets. The method we will use to measure conductivity is interdigitated electrodes as it allows us to get a direct measurement of the conductivity for each peptide.
