Glad to share the artwork of our DNA supercoiling work now in the cover of @MolecularCell ! This cover was inspired in traditional Peruvian embroidery @peru 🇵🇪 to represent artistically our findings on apical localization of RNA polymerases on DNA plectonemes.

Happy to share a collaborative project from my postdoctoral work that is now published in ACS Nano, with @katy_requejo leading the work as the first author.

This was the last project I worked on during my postdoc at Berkeley, and it continued over the past few years while I have been at Georgia Tech, making it especially exciting to finally see it published.
We investigated the mechanics of photochemical propulsion in Janus micromotors and quantified the propulsion forces at the single-particle level. 🔬 🚀

It was a pleasure to be part of this collaboration.

❤️ Team DNA Supercoiling!

[UChicago Chemistry @UChiChemistry]

Precision is the heart of nanotechnology. Nowhere is that more evident than in the work of University of Chicago President and renowned chemist Paul Alivisatos, whose latest study in ACS Nano provides a definitive look at the mechanics of photochemical propulsion.

Joining with a team of researchers from UC Berkeley, the group explored the dynamics of Janus micromotors—asymmetric particles that convert light into directed motion. By moving beyond bulk observations to a single-particle framework, the team has quantified the exact force behind the "swim," capturing measurements in the 4.5–6.2 pN range.

The Result: A new blueprint for bridging the gap between chemical energy and mechanical work. Link: https://t.co/JMEsAhXbhE

Excited to share our new work published in @MolecularCell: “Apical localization of RNA polymerases modulates transcription dynamics and supercoiling domains revealed by cryo-ET”. We directly visualized transcription-induced DNA supercoiling domains in 3D! https://t.co/3TEtfoQfRO

In this work co-led with @Meng3054 , we trace in 3D the structure of DNA plectonemes and provide insight into how transcription and DNA supercoiling affect each other. Congrats to all the team involved!

We also observe that reducing rotational diffusion by functionalization with long DNA strands enhances the directionality and propulsion of these light-activated Janus particles.
