Super cool work !

Kinetic Insights Into Carbon Nanotube-Based Neurotransmitter Sensors by Single Molecule Experiments Single-walled carbon nanotubes (SWCNTs) are powerful building blocks for near-infrared (NIR) fluorescent biosensors. They can be chemically tailored to detect specific biomolecules. Their performance ...

Congrats to Juliana! She measures in ACS Nano the rate constants of nanosensors on the single molecule level. She found two kinetic pathways and one can use this knowledge for Kinetically Improved Sensor Selectivity (KISS). @solvationsci.bsky.social @ruhr-uni-bochum.de

✨ 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!

Self-blinking dye restores efficient use of nanobodies in single-molecule localization microscopy. Direct STORM relies on robust fluorophore blinking; observations suggest that AlexaFluor647 underperforms when coupled to nanobodies, thereby undermining the advantages of nanobodies. We show that the...

A cool thing was the FRET-based diffusion analysis that allowed a separate analysis of MET receptor monomers and dimers👇🏻

Super-resolved Imaging of Molecular Interactions Using FRET-SOFI Super-resolution fluorescence microscopy is a powerful method to image molecular processes that occur beyond the diffraction limit of light. Förster resonance energy transfer (FRET) is widely used to ...

Excited to share our latest work! We introduce FRET-SOFI, a new method for super-resolved imaging of molecular interactions. By combining SOFI with FRET, we achieve subdiffraction resolution in live cells using standard wide-field microscopy.

Proud to see this preprint out!

First time demonstrated Confocal MIET DNA-PAINT and has been a challenging but rewarding journey, and I’m excited about the possibilities it opens for 3D multiplexed nanoscopy in cells.

Looking forward to advancing nanoscale imaging and molecular mapping at LMU Munich, and to many more exciting synergies ahead!
