Happy to share our new publication on liquid crystal #microlasers. We show that bipolar spheres confine light in only a single plane. Interestingly, the bipolar refractive index profile also induces a splitting of the whispering gallery modes. Why? Check-out the paper to find out! #WGM #research

🎉 We are excellent The #UniCologne has succeeded with its proposal “Neue Universität: Continuous Change – Successful Renewal” and has been awarded the status of a ‘University of Excellence’ as part of the Excellence Strategy of the Federal and State Governments ➡️uni.koeln/SWUK7

🧫✨ New paper in @wiley.com: Optical Manipulation of Whispering Gallery Mode Microlasers for Controlled Cellular Delivery We use laser tweezers to place microlasers onto single cells and watch their uptake in real time: doi.org/10.1002/adom... @thegatherlab.bsky.social @centrelightlife.bsky.social

🎉Important day for our Department! The construction of the new building for Chemistry and for Teacher Education is progressing at pace. Completion of the first part is anticipated for 2029🤞, enabling research and teaching in close proximity. And it already looks FANTASTIC!

A new, flexible microlaser can measure tiny forces within a living cell. “The applications we see are related to force measurements in clinically relevant cell models, primarily in stem cell‒derived heart organoids,” Marcel Schubert, @unicologne.bsky.social https://bit.ly/4dqQXUJ 💡 ⚛️ 🧪

Optical sensing of biological #forces with #microlasers, now published in @opg.optica.org. Data from Melisa's master thesis, with additional cell data measured by David. So great to have a solid+soft material as alternative to oil droplet microlasers. doi.org/10.1364/OME.... (open access)

Still time to register for Malte's discussion with the Optica editors on #biophotonics, #microlasers and organic #electronics (this week Friday).

Finally deactivated that dormant account on the #X hellscape #RIP #Twitter. Surprised and sad to see so many academics still posting there, you can do better!

THREAD The first full year of tracking research on @bsky.app Hi, we are Altmetric, and we track how research is communicated across the web. We now have one full calendar year of Bluesky research data and thought we'd have a looksie.

Very happy to finalize a few projects after a busy year, starting with a pre-print of Melisa's work on #flexible #microlasers made from #elastomers! A great material to prepare soft microlasers to measure biological #forces. #biophotonics #biosensing arxiv.org/abs/2512.22707

Really important new paper on how AI can be used to fake nanoparticle images #chemsky #science #nanotech www.nature.com/articles/s41...

Is anyone still reading review papers these days? For those who do, check out our #review (open access) on #biointegrated #microlasers, now published in @optica.org. doi.org/10.1364/OPTI...

Grateful to have been included in a Feature in ‪@theobserveruk.bsky.social‬ focussing on "fake spotters", available online today. This gives an overview of our work to tackle counterfeit spirits using laser spectroscopy, which we hope to see in use very soon! observer.co.uk/style/featur...

Very happy to contribute to #BIOspektrum! My short (3 pages) take on the applications and potential of #microlasers for #biosensing and #singlecell tracking. Open access👉 rdcu.be/elhkx (in German) Thanks @gbmev.bsky.social, @gesvirologie.bsky.social and @riemerlab.bsky.social 😉 for the invitation!

🧬🔬New paper online: Nucleic acid sensing using DNA-functionalized whispering gallery mode microlasers! Great collaboration with @thegatherlab.bsky.social @sorayacaixeiro @schubertlab.bsky.social @chemunicologne.bsky.social 🧪 #DNASensing #microlasers pubs.acs.org/doi/full/10....

New paper online: Half-wave nanolasers and intracellular plasmonic lasing particles. A metal–semiconductor as small as 170 nm in diameter emits lasing light from the lowest-order plasmonic mode across a broad spectral range in the infrared. www.nature.com/articles/s41... #Nanotechnology

Schlieren textures and topography make organic polariton lasers better! To the point where lasing is achieved with simple metallic mirrors for the first time. Great work by Florian Le Roux, @andreasphysics.bsky.social and Francisco Tenopala Carmona. Check out our Nature Comms paper rdcu.be/d6GXz

Glad that our latest paper has generated interest and has been selected to be featured on Nature Protocol's website. @natureportfolio.bsky.social @uarizona.bsky.social @spie.org @optica.bsky.social

JOB ALERT! 2 open PHD positions @kathlab.bsky.social in the framework of the MSCA doctoral network MeChaNiSM! Searching for organic chemists dedicated to nucleic acid chemistry.🧬⚗️🎉 More info: www.kathlab.uni-koeln.de #organicchemistry #nucleicacids

Exceptionally well produced video about the mechanics of the developing crocodile head scales. Outstanding #microscopy data backed up by detailed simulations! Very inspiring.

#Polaritons enable high performance angle-independent optical filters. Immensely enjoyed this collaboration between @thegatherlab.bsky.social, the Vandewal group at UHasselt and University of St Andrews rdcu.be/d2hUo

Excited to be among the recipients of the 2024/25 Zia Fellowship! In today’s newspaper @zeit.de you can read more about the fellows and our science - or check out zeitfuerx.de/forschung/zia/ 👩🏼‍🔬💡

Good time for a re-post of Vera's @veratitze.bsky.social paper on integrating an ultrafast spectrometer (100k spectra per second!) into custom-built and commercial confocal microscopes. Plus demonstration of our intracellular #microlasers for single cell #tracking and #sensing.

I'm trying to find all the cool people sharing microscopy here. Help me 🤓🔬 go.bsky.app/Aaf8sKT

"Deformable microlaser force sensing" now published in Light: Science & Applications! We show that #droplet #microlasers can measure absolute mechanical #forces inside cells, tumour spheroids, and in vivo! www.nature.com/articles/s41...

Hello bluesky! Now posting news from our lab, cool science from all over the world, and the occasional job offer on this platform. Long may it last. #microlaser #photonics #nanooptics #sensors #science schubert-lab.uni-koeln.de
