In DNA-PAINT, nearby proteins create overlapping localizations. You may see two by eye, but analysis often misses them, wasting precious precision. G5M solves this. Now in @natcomms.nature.com. doi.org/10.1038/s414.... 1/7

Honoured to receive the Young Fluorescence Investigator Award at #BPS2026! Huge thanks to the selection committee and to all the mentors and colleagues who supported me. Excited to start new projects and keep using fluorescence to uncover molecular biology!

We are happy to share our latest work, 4Pi-SIMFLUX, which combines structured illumination with interferometric detection to achieve near-isotropic 3D localization precision of 2–3 nm and resolve sub-10 nm structural features across whole mammalian cells. www.nature.com/articles/s41... rdcu.be/eQVxt

Our article "Ångström-resolution imaging of cell-surface glycans" made it to the cover of Nature Nanotechnology! 🤩 @natnano.nature.com www.nature.com/nnano/volume...

Thrilled to announce some big news! Excited to share that I’ve been awarded a Wellcome Trust Early Career Award to establish my research as a Group Leader in the Glycosciences Program at the Institute of Biology and Experimental Medicine (IBYME) in Buenos Aires, Argentina, beginning in early 2026.

Within this neuronal atlas we can reveal the three synapse classes, excitatory, inhibitory and the recently discovered mixed synapse. Organelle imaging of Peroxisomes (Pmp70) and the Golgi Apparatus (Golga5) reveals rare contact sides and even fused particles. (5/6)

To show the power of the technique, we acquired a 13-plex 200 x 200 µm2 neuronal atlas in 3D. With this atlas we map the interaction architecture of three neurons, resolving organelles, cytoskeleton, vesicles and synapses at single-protein resolution. (4/6)

We demonstrate speed-optimized left-handed DNA-PAINT by characterizing the sequence binding kinetics and resolving three main microscopy benchmarking targets, mitochondria, microtubules and nuclear pore complexes with <5 nm localization precision. (3/6)

The mirrored design of left-handed oligonucleotides allows the extension of the common 6 speed-sequences R1-R6 with their analogs L1-L6, enabling 12 target multiplexing with a standard secondary label-free DNA-PAINT workflow. (2/6)

Highly efficient 12-color multiplexing with speed-optimized DNA-PAINT. We are excited to share our latest paper in @natcomms.nature.com, using left-handed DNA to extend speed-optimized DNA-PAINT to 12 targets in a simple and straightforward way! 🧬👈🚀https://www.nature.com/articles/s41467-025-64228-x

IMAGING LIGAND-RECEPTOR INTERACTIONS AT SINGLE-PROTEIN RESOLUTION WITH DNA-PAINT🔬 Ever wonder how cells "talk"? It starts when ligands bind to receptors on cell surfaces. We have cracked the challenge of imaging small ligands on cell surfaces. #DNAPAINT #celltalk 💬 doi.org/10.1002/smtd...

Check-out this powerful application of DNA-PAINT and RESI: imaging ligand-receptor interactions at molecular resolution! Project led by my extremely talented colleagues Monique Honsa, Larissa Heinze and Isabelle Pachmayr Very happy to have contributed to this beautiful work! 🤩

One month ago today, I published my first paper with the @jungmannlab.bsky.social 🥳 What better way to celebrate #MicroscopyMonday than with this STAR Protocol on SUM-PAINT spatial proteomic imaging: a guide for highly multiplexed DNA-PAINT imaging in neurons. star-protocols.cell.com/protocols/4066

An interesting preprint from the Horrocks' lab detailing the behavior of secondary nanobodies (such a @nanotag.bsky.social ones) at the single molecule level and optimizing protocols for multiplexed labeling: doi.org/10.1101/2025...

Mike spotted this before the rest of us. 🫡 Publications from 2025 are shared more on Bluesky than on X/Twitter.

To anyone who were excited for the release of SUM-PAINT, we now published a detailed protocol on to how replicate it in your hands! Check it out here: doi.org/10.1016/j.xp...
