New Preprint!
Ex-dSTORM resolves fine details of the molecular architecture of CCPs, the 8-nm periodicity of microtubules, and the docking site of synaptic vesicles at the presynapse of hippocampal neurons.

Great news: I received ERC Advanced grant #ERCAdG @erc.europa.eu CaptuRel! It aims at intelligent nanomaterials undergoing bioinspired cycle of capture and photorelease of bioactive molecules for sensing and controlling (bio)chemical gradients. Thanks to my Team, @cnrs.fr and @unistra.fr!

De novo designed bright, hyperstable rhodamine binders for fluorescence microscopy by Bo Huang and team: www.biorxiv.org/content/10.1...
Fig. 4 Super-resolution microscopy in live and fixed cells with Rhobin.
(A) Rhobin transiently binds rhodamine molecules and thereby constantly replenishes signal lost
through photobleaching of dyes. (B-D) No-wash STED microscopy of live U2OS cells transiently
expressing LifeAct-Rhobin2 labeled with 100 nM JFX650. (C, D) Zoom-ins of regions highlighted
in (B) imaged either with confocal or STED microscopy. Scale bar: 20 μm (B) and 10 μm (C, D).
(E-H) Rhobin enables timelapse STED microscopy of fast ER dynamics with minimal signal loss.
U2OS stably expressing N-terminal tag fusions of SEC61B were stained with 1 μM Halo-JFX650
(HaloTag7, reHaloF) or 2 μM SiRhP (Rhobin2) and imaged at a frame rate of 0.387 fps for at least
100 time points. (F, G) Selected frames from timelapse acquisitions of Rhobin2:SEC61B labeled
with SiRhP (F) or HaloTag7:SEC61B labeled with Halo-JFX650 (G). Scale bar: 2 μm. (H) Signal

loss during timelapse imaging. Mean ± SD signal inside cells over time for indicated constructs.
(I-K) PAINT-type super-resolution microscopy with Rhobin. Rhobin2-SEC61B was transiently
expressed in U2OS cells and labeled with 5 nM SiRhP after chemical fixation. Imaging under no-
wash conditions and near-TIRF illumination. (I) Repeated, but transient binding of SiRhP
molecules to Rhobin2 at low nanomolar concentrations can be observed as intensity bursts in
intensity time traces extracted from a diffraction-limited area. See movie S3 for raw data of
binding-induced blinking. (J) Sum image across 10,000 frames of an image stack, simulating a
diffraction-limited image. (K). Reconstructed image from localized molecules in the full stack.

🚨 New preprint!
Using U-ExM + in situ cryo-ET, we show how C2CD3 builds an in-to-out radial architecture connecting the distal centriole lumen to its appendages. Great collab with @cellarchlab.com @chgenoud.bsky.social @stearnslab.bsky.social 🙌. #TeamTomo #UExM

Very excited to present our latest work: SPINNA, an analysis framework and software package for single-protein resolution data! 🖥️🤩

We can directly quantify stoichiometry and oligomerization from super-res (DNA-PAINT, RESI) images!! 🧬🎨

I'm thrilled to share that our review article, "Molecular Level Super-Resolution Fluorescence Imaging," has now been published online (www.annualreviews.org/content/jour...)! We provide a comprehensive overview of fluorescence super-res methods that push the limits towards molecular-scale imaging.
Molecular Level Super-Resolution Fluorescence Imaging | Annual Reviews
Over the last 30 years, fluorescence microscopy, renowned for its sensitivity and specificity, has undergone a revolution in resolving ever-smaller details. This advancement began with stimulated emis...
