Ulijn Group, 2020

Welcome to the Ulijn Group website. Our lab is focused on the use of simple versions of the molecular building blocks of life to produce materials and systems with controllable structural, photonic, electronic, and biological properties. These properties open up wide-ranging applications in energy, biomedicine, environmental protection, food, cosmetics, and personal care. [Group Members and Full Biography]

In Situ, Noncovalent Labeling and Stimulated Emission Depletion-Based Super-Resolution Imaging of Supramolecular Peptide Nanostructures

Latest Paper Image

This paper by Mohit, with contributions from Jiye, Richard and Deborah demonstrates a new and remarkably simple method to fluorescently label peptide nanostructures for their visualization in solution with super-resolution microscopy. We show that by simply mixing a small amount (0.1 mole%) of a commercially available dye (Alexa-488) with cationic self-assembling peptides gives rise to selective electrostatic association of the dyes with the peptide nanostructure surface, which enables imaging using Stimulated Emission Depletion (STED) super-resolution microscopy. The method gave new insights into the hierarchical organization of peptide nanostructures, and enabled visualization of enzymatic degradation of peptide nanofibers which could be imaged in real-time in situ.
