Great collaboration with @philiptinnefeld.bsky.social and Lela Vukovic. Special congrats to Izabela and Justus. We show in @angewandtechemie.bsky.social that carbon nanotubes quench dyes with a beautiful d^-5 scaling law. Interesting perspectives for nano engineering...

Detection of C-Reactive Protein in Serum with Near-Infrared Fluorescent Sensors The human immune system is central in the defense against pathogens but is also involved in autoimmune diseases. Inflammatory processes are orchestrated by biomolecules, including the inflammation mar...

Congrats to Christina on her work in ACS Sensors. She developed a new biofunctionalization strategy for biosensors to detect CRP in human serum, which is an important biomarker for inflammation. @ruhr-uni-bochum.de @solvationsci.bsky.social pubs.acs.org/doi/10.1021/...

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

Check out Valeriia's elegant photochemistry approach in @angewandtechemie.bsky.social to incorporate quantum defects in nanomaterials without compromising quantum yield or making later biofunctionalization more challenging. Congrats! lnkd.in/eaxaECt6 @solvationsci.bsky.social @ruhr-uni-bochum.de

Check out Björn's cool insights into near infrared signals from photosensitizers. It is correlated but does not origin from singlet oxygen. The signal is present in all samples we looked at (labeled vesicles, plants,...). @solvationsci.bsky.social @ruhr-uni-bochum.de tinyurl.com/5dvsrnde

Die Regenbogenfarben des Kohlenstoffs Im Labor von Sebastian Kruss überrascht Kohlenstoff mit verschiedenen Farben. Die Bochumer Forschenden experimentieren mit den bunten Winzlingen für biomedizinische Anwendungen.

Kohlenstoff-Nanoröhren sind nicht nur hübsch anzuschauen. @krusslab.bsky.social entwickelt aus ihnen Sensoren für die personalisierte Medizin – und verfolgt zudem die Vision von smarten Pflanzen. 🌿

Check out Jan's paper @acs.org Anal. Chem. We developed a simulation to quantify advantages of the near infrared and use the insights to create a diagnostic test/device for levodopa in blood serum for better Parkinson's treatment. @ruhr-uni-bochum.de @solvationsci.bsky.social tinyurl.com/2zvhtxcr

We are looking for a motivated postdoc to join our lab as Humboldt fellow via the Henriette Herz scouting program as soon as possible. If you are interested in optical spectroscopy/microscopy, biosensing or nanomaterials please contact me. Please RT! @solvationsci.bsky.social @ruhr-uni-bochum.de

Millionenförderung für unsere Exzellenzcluster! 🎉 Wir gratulieren den Forschenden der Cluster CASA und @solvationsci.bsky.social zu ihrem verdienten Erfolg.

Despite its abundance, there are still many unanswered questions about water's behaviour. RESOLV doctoral researcher Adrian Buchmann explains in his Science Slam how science is trying to unravel the mystery of water. Watch the full video!

Very happy to contribute to #BIOspektrum! My short (3 pages) take on the applications and potential of #microlasers for #biosensing and #singlecell tracking.

Thanks @gbmev.bsky.social, @gesvirologie.bsky.social and @riemerlab.bsky.social 😉 for the invitation!

Juliana's workflow to 3D print carbon nanomaterials is now published online in CARBON Trends. Very cool to illustrate their properties, biosensing as well as teaching basic concepts in physics/chemistry. @solvationsci.bsky.social @ruhr-uni-bochum.de tinyurl.com/9fuxe5f2

Neue Echtzeit-Methode für die Umweltüberwachung Mikroplastik detektieren oder Pflanzenschädlinge frühzeitig erkennen – das und noch viel mehr ermöglicht ein neues Verfahren, welches auf Nahinfrarot-Licht-Messungen basiert. Es ist günstig und funkti...

Kunststoff ist nicht gleich Kunststoff. Für das Recycling ist es wichtig zu wissen, mit welchem Material genau man es zu tun hat. Eine von @krusslab.bsky.social entwickelte Methode könnte dabei helfen – und sie kann noch viel mehr.

There is a fantastic workshop coming up on single-molecule spectorscopy and super-resolution microscopy in Berlin (September 23 - 26, 2025) - an outstanding row of keynote and invited speakers!

Jan's work on a spectral phasor approach for very fast and simple hyperspectral imaging (HyperNIR) is online in Advanced Science. It is a beautiful and astonishing method for label-free imaging of different types of plastics and plant health as well as fluorescence signals. tinyurl.com/4epsba8e

Happy to share our latest preprint rb.gy/py8q7a in which we demonstrate that ultrashort carbon nanotubes have astonishing brightness in the SWIR which propels them as amazing probes for bio-imaging in brain tissue (here in 3D SPT experiments). Yes, brighter than quantum dots and in the SWIR!

Congrats to Alex. He shows in J. Phys. Chem. C how to incorporate two different types of quantum defects in fluorescent carbon nanotubes. It opens new dimensions to tailor photophysics and surface chemistry.

Great collaboration with the Borchardt group. It is possible to incorporate tiny numbers of quantum defects in
nanotubes using mechanochemistry and tune their fluorescence. Congrats Miriam and Justus. @solvationsci.bsky.social @ruhr-uni-bochum.de @angewandtechemie.bsky.social tinyurl.com/4dws5c7c

Congratulations to Chen. She shows in JPC C that solvatochromic dyes on carbon nanotubes modulate/improve their biosensing performance. For example for pH sensing or detection of lipids, which is often a challenge. @solvationsci.bsky.social @ruhr-uni-bochum.de tinyurl.com/3kyy3zu6

Mode of action of the new microscopy method LLS-TDI-DNA-PAINT. On the top right, the RTX antibody was visualised on a Raij-B cell: it is easy to see how it links the CD20 molecules in the membrane. Bottom right: the hedgehog-shaped appearance of a living Raji B cell after the antibody has bound. The surface protein CD45, which is homogeneously distributed on the cell surface, is also labelled in green. (Image: Arindam Ghosh / University of Würzburg)

Delighted to launch our activities on Bluesky with this great news: Our researchers @sauer-lab.bsky.social show in @science.org, how therapeutic #antibodies interact with B cells – thanks to an innovative method of super-resolution microscopy. Congratulations!
