Bryce is an analytical chemistry PhD candidate at the University of Utah in Salt Lake City, Utah, in Joel M. Harris’s research group. He received a B.S. degree in chemistry from Central Washington University in Ellensburg, Washington. During his undergraduate studies, he worked with Professor Dion Rivera, using attenuated total reflectance–Fourier-transform infrared (ATR–FT-IR) methods for investigating polyelectrolyte adsorption to oxide films. Before joining the Harris group, Bryce worked as a post bachelor’s research assistant at Pacific Northwest National Laboratory, developing infrared spectroscopic methodology for in situ study of the partitioning of contaminants between water and supercritical carbon dioxide. He is currently the SAS student representative.
Bryce’s work in the Harris research group has focused on developing and using confocal Raman microscopy methods for analysis carried out within individual chromatographic particles. More recent work has focused on the preparation and characterization of supported phospholipid bilayers throughout the pore network of chromatographic silica particles, and use of these pore-confined bilayers for label-free confocal Raman microscopy experiments to detect membrane partitioning of small molecules, specific protein binding to membrane localized ligands, and detection of signaling peptide accumulation. This work provides both quantitative and structural information about these molecular interactions with phospholipid membranes.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
