Bottom-up Investigation of Spatiotemporal Glycocalyx Dynamics with Interferometric Scattering Microscopy Over recent decades, the glycocalyx, an extracellular organelle composed of a multitude of glycolipids, glycoproteins, proteoglycans, and glycoRNA, has gained considerable interest in cellular biology. While research in this field has revealed its tremendous importance in ever more aspects of physiological and pathological cellular processes, many of the principles that govern the role of the glycocalyx in these processes on a molecular level are still unknown. In order to unravel the fundamental laws underlying glycocalyx function, new technologies are required that enable the distinction between individual subprocesses within the intricate environment of the glycocalyx. Here, we establish an experimental platform to investigate the dynamics of the glycocalyx at the nanometer and microsecond length and time scales in a bottom-up fashion. We synthesized defined oligosaccharides and installed them on supported lipid bilayers. This way, synthetic glycolipids were assembled to glycocalyx model systems with tunable properties. By investigating these tunable model systems with interferometric scattering (iSCAT) microscopy, we gain access to the required spatiotemporal resolution. We found a strong correlation between the molecular structure of several investigated model glycans and global dynamics of the system. Our findings are corroborated by atomistic molecular dynamics simulations and coarse-grained Brownian dynamics simulations. Our results provide the first direct experimental evidence on the relationship between glycan structure, organization, and dynamics, offering a robust and versatile basis for a quantitative understanding of glycocalyx biology and physics at the molecular level.

The cpHMD simulations now cover longer timescales, and we added new simulations with the molecule TNS. Could it modulate the surface charge?

The fragile flame of freedom flickers low, Its steady light consumed by shadows deep. Where once the people's will had room to grow, Now gilded towers rise while dreamers sleep. The streets grow quiet as the markets roar, The people lost in digital despair. No votes, no voice, but data to adore, Their power grows while we must gasp for air. Will oligarchs decide the terms of hate, And leave us slaves within their gilded dreams? Shall silicon and dollars write our fate, And bind us all and glue us to their screens? Beware, for tech may burn our hope to dust— In circuits cold, no justice can we trust.

Ich habe zusammen mit ChatGPT ein Sonett über die Bedrohung der Demokratie durch Tech-Bros geschrieben. Und jetzt weiß ich auch nicht mehr, was ich denken soll.
