This webinar focuses on the use of novel AFM-IR methods to study biomolecular processes and functional materials in native liquid environments and, for the first time, down to the single biomolecule scale.
Join us and our special guest speaker, Dr. Francesco Simone Ruggeri (Wageningen University, Netherlands), for a talk on unraveling molecular structures and interactions with single-molecule nanochemical imaging and spectroscopy.
Dr. Ruggeri, a pioneer in this field of science, has pushed the boundaries of modern microscopy and spectroscopy to study biomolecular processes and functional materials. He has demonstrated that infrared nanospectroscopy can be used to determine the chemical fingerprint and secondary structure of biological samples and materials in native liquid environments and, for the first time, down to the single biomolecule scale. His approach has led to new insights into the formation and structural characterization of the misfolding of proteins and their correlation with the onset of neurodegenerative disorders, and, by taking inspiration from nature, the production of new, sustainable substitutes for pollution-causing plastics.
The development and application of photothermal infrared absorption nanospectroscopy (AFM-IR) was a real breakthrough for the analysis of heterogeneous (bio)-molecular systems and their interactions, from the single molecule scale up to living organisms. As a major advance in the field, we have demonstrated the achievement of detecting single protein molecules by introducing off-resonance, low power and short pulse infrared nanospectroscopy (ORS-nanoIR).
By pushing the sensitivity of AFM-IR to its current limit, we have proven that the secondary structure of single protein molecules can be determined with an accuracy similar to that obtained in bulk by IR spectroscopy (Nature Comm., 2020). Our approach further enables investigation of:
This talk will also cover our goal to expand the capabilities of nanoscale vibrational spectroscopy to shed light on the structure-activity relationship of biomolecules for applications in nano-medicine, materials science and biotechnology.
