A milestone I had been chasing for a long time.
The key idea: using carbon nanotubes as perfect tunable 1D dipoles at the single-particle level, together with a dipole spread function engineering approach.
Great collaboration with Jana Zaumseil, Ben Flavel, Sophie Brasselet, and Laurent Groc
An additional small clarification: these ultra-short nanotubes are competitive with quantum dots by being quite brighter, and, above all, by emitting in the NIRII / SWIR range. A crucial asset for bioimaging and NIR photon sources!
This is a great collaboration with the amazing labs of Jana Zaumseil, Laurent Groc and Erwan Bezard
Key Highlights:
🔹 High brightness combined with nanoscale size
🔹 Nonlinear photoluminescence behavior under varying excitation conditions
🔹 PL quantum yields up to 20%
🔹 Demonstration of high-resolution, 3D single-particle tracking in thick brain tissue
🔥 Our latest research on ultrashort carbon nanotubes (uCCNTs) with luminescent color centers has been published in ACS Nano! We've discovered that these uCCNTs are exceptionally bright in the NIRII window, making them ideal for advanced bioimaging, photonics, and quantum science applications.
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!
Indeed, we are looking of a PhD student at the interface between chemistry, biophysics and biology to work on light induced LLPS. join us at @iecb.bsky.social in Bordeaux !
