New preprint alert! What if we go beyond Period 2? SWCNT defects have focused on carbon (aryl) and oxygen. But what about phosphorus from Period 3?
We introduce a simple strategy to engineer phosphorus defects in SWCNTs
Check out our preprint

@nanocarbons
Check out Christina's new work in @AdvPortfolio. She created several exciting new quantum defects in @nanocarbons and also specifies the role of oxygen, etc for the reaction. Congrats! @ruhrunibochum @Fraunhofer @SolvationSci tinyurl.com/39xwuu9u
Congrats to Valeriia Andreeva and Chen Ma! They engineered a near infrared fluorescent (and ratiometric) pH sensor using quantum defect chemistry on @nanocarbons and shed light on how it works.

🌟 Tiny defects, big sensing possibilities! Our new Perspective in Small explores how defects, molecular coatings, and analytes work together to shape carbon nanotube sensing:

Excited to share our new paper in @ACS_AMI! We show that NIR-fluorescent single-walled carbon nanotubes can serve as multiplexed reporters of trigger-induced peptide self-assembly, revealing pathway-dependent dynamics. @ACSPublications

Are you interested in detecting catecholamines ? Check out Julia's perspective in @JNeurochem together with Andreas Reiner. We compare @nanocarbons sensors and genetically encoded ones and discuss their potential. @ruhrunibochum @SolvationSci tinyurl.com/593s8yum
Congrats to Juliana to her paper in @ACSChemNeurosci . She created a computational (stochastic kinetic) framework to predict how the image of sensors ( e.g. @nanocarbons or others) looks like in response to molecules released by cells. @SolvationSci

Check out or joint work with the Erpenbeck lab on fluorescence lifetime imaging of membrane tension. Beautiful data that shows that mechanical properties and processes are highly important in biology. @SolvationSci @ruhrunibochum

One of our most important findings so far together with the Erpenbeck lab: We reveal that immune cells release and take up catecholamine neurotransmitters (dopamine) + respond to it, which has important implications for medicine. tinyurl.com/568y46ry @nanocarbons @SolvationSci
We are looking for a postdoc to work on light induced quantum friction of carbon nanotubes in water (see nature.com/articles/s41586-0…) funded by our cluster RESOLV (TV-L E13, 2 years). A background in optics, microscopy, spectroscopy or materials is optimal. #postdoc #AcademicJobs

🎆New Paper! 🎆 Preformed, self-healing hydrogels carrying near-infrared @nanocarbons nanosensors can pass through a fine needle, recover immediately, and detect L-DOPA in serum and tissue phantom: toward minimally invasive drug monitoring! @TelAvivUni

Many thanks to @ArdemisPrime for visiting us in Bochum and sharing her vision about future sensor design. It was great to catch up and brainstorm about future technologies. @nanocarbons @ruhrunibochum @SolvationSci
1/4 Check out our work with the Sulpizi and Havenith labs @Nature. We show that light can slow down diffusion of small objects (@nanocarbons), find a THz signature for it in the water and support it by simulations. @ruhrunibochum @SolvationSci nature.com/articles/s41586-0…
3/4 Optical pump probe THz spectroscopy probes the water structure and we found a unique feature that we assign to the exciton water interaction. Because of the time scales we propose that this pathway allows the nanotube to exchange momentum with the water via quantum friction.
Looking forward to the talk from Ardemis, a global leader in biosensor design and research. @ruhrunibochum @SolvationSci
Excited to speak at tomorrow's RESOLV seminar on AI for medical diagnostics and next-generation sensors.
Thanks to @KrussLab for the invitation!

New paper online: Chemical efflux imaging using an annular nanosensor array for in situ bladder cancer detection.
"A catheter-integrated carbon nanotube #nanosensor array enables NIR mapping of bladder #cancer biomarkers with 182× higher sensitivity."

Integrating experimental and computational approaches we elucidated the role of nanoparticle size and cross-linking on plant cell wall-nanoparticle interactions for advancing plant nanobiotechnology and nano-enabled agriculture.

Monitoring Molecules in Neuroscience (MMiN) conference in Amsterdam abstract deadline is approaching. monitoringmolecules.org/spea…
Highly interesting for anyone interested in neurochemical technologies. There will be also a symposium on @nanocarbons for neuroscience.
