Immunosensors use antibodies to detect and quantify biomarkers of disease, though the sensors often lack structural information. We create a surface-sensitive two-dimensional infrared (2D IR) spectroscopic immunosensor for studying protein structures

UV light and other factors damage crystallin proteins in the eye lens, resulting in cataracts that scatter light and affect vision. Little information exists about protein structures within these disease-causing aggregates. We examined postmortem len

The structures of many membrane-bound proteins and polypeptides depend on the membrane potential. However, spectroscopically studying their structures under an applied field is challenging, because a potential is difficult to generate across more tha

The majority of 2D IR spectrometers operate at 1-10 kHz using Ti:Sapphire laser technology. We report a 2D IR spectrometer designed around Yb:KGW laser technology that operates shot-to-shot at 100 kHz. It includes a home-built OPA, a mid-IR pulse sha

Laminates made of graphene oxide nanosheets have been shown to exhibit high water permeance and salt rejection and, therefore, have generated immense interest from the scientific community due to their potential in separation applications. However, t

We use two-dimensional IR (2D IR) spectroscopy to explore fibril formation for the two predominant isoforms of the β-amyloid (Aβ1–40 and Aβ1–42) protein associated with Alzheimer’s disease. Two-dimensional IR spectra resolve a transition at
