This research focuses on alternatives to nafion in a fuel cell membrane by using tripeptides for a more efficient and well-rounded proton transfer. From previous research, it is clear that the FMOC capped tri-peptides are able to self-assemble into nanowires through the use of Atomic Force Microscopy (AFM). Since multiple amino acids including aspartic acid, histidine, lysine, and more have been tested their scans can be compared to see common trends. Some of these trends can be seen from even the early stages of sample prep. Despite keeping concentrations of peptides the same by using 20mM solutions there are differences in viscosity and opaqueness which is a clear indicator that the reactivity is not all the same. Looking at the scans, this is also obvious from the various thickness, spacing, and packing of the nanofibers. Tracking these trends is the next step in understanding how they work and their potential to transfer protons.<br/>
