Nanoparticles have become common in many real world devices, including catalysts, data storage devices, sensors and solar cells. This increase in usage is due to the ability of the nanoparticles to easily assemble into two-dimensional structures with various useful optical and electronic properties. The goal of this summer project was to 1) research current applications of metal nanoparticles relevant to the gold nanoparticle-embedded nanosheets formed in our lab and 2) to use computer software to analyze atomic force microscopy (AFM) images of gold nanoparticle-embedded nanosheets formed in our lab this summer. In the lab, we are aiming to create and characterize stable planar gold nanoparticle materials, such as emulsions and nanosheets, by assembling the gold nanoparticles with peptoids at fluid surfaces. The characterization of these materials is accomplished through AFM, which is used to analyze the heights of the nanosheets and to determine whether or not they can be successfully formed both with and without gold nanoparticles. The AFM images obtained this summer were processed and analyzed using IgorPro so that the heights of the different materials could be obtained and compared. This project is based on work from the previous 2019-2020 academic year.
