Our preprint on Antarctic fish cell cultures is out now! Loads of pretty nice super-resolution images. Read it here: www.biorxiv.org/content/10.6...

New paper out 💥 3D cell-cell contact reconstitution with synthetic vesicles and (primary) immune cells to study how different proteins and carbohydrates influence the immune synapse dynamics. advanced.onlinelibrary.wiley.com/doi/10.1002/...

Haven’t taken a flight in 14 months ✈️ Won’t take one until April either, which’ll make it 17. Just a reminder that travel choices do add up for CO₂. One person skipping a flight doesn’t ground a plane, but lower demand over time does mean fewer routes and frequencies.

Bored over the holidays? Give our new preprint on how #microtubule lattice alteration by taxols can regulate #RhoA #signalling via GEF-H1 a read! Perhaps a new mechanism of action for taxol #chemotherapeutics during interphase. www.biorxiv.org/content/10.6... Happy holidays ✨🎄

✨ Blinking #nanobodies that work for single-molecule localization 🔬 Our new preprint shows that the self-blinking dye JF635b restores robust, buffer-free blinking in #nanobodies, enabling reliable #dSTORM, #MINFLUX, and more, without chemical-switching buffers. Opening new possibilities for #ExM!

I was incredibly fortunate in this! The ups and downs were many but all those discussions helped make sense of a few scientific questions that are still ongoing and lead to further questions.

Tracking coordinated cellular dynamics directly from images -- New method paper by labmates @bgraedel.bsky.social & @macdobry.bsky.social ! Python package & @napari.org plugin, all the good stuff: Paper: doi.org/10.1242/jcs.... Code: github.com/pertzlab/arc... Plugin: github.com/pertzlab/arc...

New paper out! Combining single-objective light-sheet microscopy and time-resolved SPAD array detection, we massively accelerate fluorescence lifetime imaging (FLIM) compared to confocal FLIM, making FLIM applicable to 3D specimen such as organoids and embryos. www.nature.com/articles/s42...

Fantastic night at Christ’s college for the LAG-MNG Christmas meal! @lasergroup.bsky.social

I won’t buy a lens from you after seeing you put it upside down. 🙃

Nature’s optics at its best! A full lunar halo lighting up the night.

PhD studentship available on using our single-molecule flow cytometry technology to detect rare proteins. Apply if you're interested in applying single-molecule techniques to improve diagnostics and to discover new routes for anti-cancer immunotherapy. www.findaphd.com/phds/project...

Single-molecule friends! The prelim. program of next year's sm- #Gordon conference in Switzerland is online: www.grc.org/single-molec... It'll be 3x fantastic: science, people, place in the alps ⛰️. Kevin & I hope to see you all next June: Have a look, tell your friends, and register!

Thrilled to see interest in this preprint! This work was a major part of my PhD, my hope is that single-molecule flow cytometry can be useful to the community in exploring new applications and discoveries. doi.org/10.1101/2025...

👀 What if your flow cytometer could see the invisible? Our new preprint introduces single-molecule flow cytometry (smFC), pushing detection sensitivity 10–80× beyond conventional flow cytometry. www.biorxiv.org/content/10.1...

How many photons are in a GFP? — more than last year, and more than you thought. Here's a simple, cheap, and practical method to break a fundamental limit in fluorescence microscopy. But it only works in light sheet!

I was searching for a Python utility for Fourier Ring/Shell Correlation. All I got in a blue sky search were 4 small posts from @christletx.bsky.social ... all I got from chatgpt was installation instructions for non-existent libraries and github repos... anyone know a good tool for this?

Production has started for a new #Snoutscope objective, AMS-AGY v3. It has significantly larger FOV and some other tweaks from v1 and v2. Currently accepting pre-orders. The price will need to increase modestly after deliveries start late October.

Check out our latest preprint, which is the latest production from our long-lasting collaboration with Andrey Klymchenko > functionnalizing NPs with humanized antibodies (i.e. Trastuzumab). Work performed by @vmittelheisser.bsky.social & O.Lefebvre in my lab. www.biorxiv.org/content/10.1...

They showed how the conformational dynamics of single molecules can be retrieved from FRET correlation functions in diffusion-based smFRET experiments. www.nature.com/articles/s41...

Claim to deliver 10 nm in xy an 25 nm in z loc precision (no FRC provided?). Photon-efficient and 100x faster (!), compared to what? www.biorxiv.org/content/10.1...

Silicon-assisted interferometric Localization Microscopy (SiLM) Clever chip engineering for interferometric SMLM. It sounds an alternative if you can’t build 4Pi/iPALM. Would love to see some FRC-based resolution comparisons to really benchmark it. www.biorxiv.org/content/10.1...

SMLM shows us how close molecules are, but just because two molecules are close doesn’t mean they’re bound. This new probabilistic framework changes that. They can actually quantify interactions at the single-molecule level. Fascinating! www.pnas.org/doi/abs/10.1...

Need to play more with it but so far works great on this OPM data.

Happy International Women's Day 💐💡

Excited to start my postdoc at the University of Cambridge and British Antarctic Survey, working in Prof. Clemens Kaminski’s group, co-supervised by Prof. Melody Clark. Some very cool super-resolution microscopy to come! Can't wait to share what we discover!

This is a useful piece of work! Well done! I really enjoyed getting involved. If your lab struggles with temperature fluctuations and you have a remote focus system, we've got just the solution. Check it out!
