Application until May 3rd
Leibniz Institute of Photonic Technology and Friedrich Schiller University Jena cordially invite you to this public lecture by Prof. Isao Noda from the University of Delaware/ USA.
The work of the Biopolymers group covers three topics: the structural investigation of aggregated proteins in amyloid fibrils, the sequencing of DNA/RNA strands and the identification of individual components of microorganisms. In the experiments, near- and far-field Raman spectroscopic methods are used to characterize samples from the micrometer to the nanometer scale. This way, label-free insights into the structural and chemical composition of biological surfaces are obtained which are inaccessible with other methods.
In particular, tip-enhanced Raman spectroscopy (TERS) enables morphological and structural characterization of biopolymers with high sensitivity (single molecule basis) and high spatial resolution (< 1 nm).
In the experiments, the chemical structure of biopolymers is investigated label-free and non-destructively on a single particle basis under in-vitro conditions. The identification and localization of individual structural elements on microorganisms allows conclusions to be drawn about their surface composition.
