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
🔹 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.

Ultrashort Carbon Nanotubes with Luminescent Color Centers Are Bright NIR-II Nanoemitters
In the fields of bioimaging, photonics, and quantum science, it is equally crucial to combine high brightness with a nanoscale size in short-wave infrared (SWIR) emitters. However, such nanoemitters a...

Thérapie cellulaire : ça coule de souche
Les cellules souches utilisées en recherche sont soit directement issues de l’embryon soit induites à la pluripotence à partir de cellules adultes différenciées. Ces dernières offrent à la recherche une nouvelle voie d’exploration thérapeutique pour de nombreuses maladies. Comment les exploiter ?

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!
