LAI members publish in Nanoletters!

LAI members Laurent Limozin,  Anaïs Sadoun and Pierre-Henri Puech and former trainee Marie-Julie Dejardin recently published in Nanoletters (IF=12) on Lamellipod Reconstruction by Three-Dimensional Reflection Interference Contrast Nanoscopy (3D-RICN). You can read the paper here: https://pubs.acs.org/doi/ipdf/10.1021/acs.nanolett.8b03134.

Congratulations !

LAI welcomes new visiting students!

LAI will have two upcoming visiting students:

Eider Nunez Viadero who comes from the Biofisika institute in Bilbao (Spain).
She will stay for three months, till December 3rd, and do high speed AFM on a potassium channel with Arin Marchesi.

Clotilde Nodet, pharmacy students in her fifth year, will be doing a part-time six month elective until february 28th. She will work on effect of Natalizumab on lymphocyte adhesion and migration with Olivier Théodoly, Marie-Pierre Valignat and Philippe Robert in La Conception.

Welcome!

 

A new article on three-dimensional reconstruction of the cell lamellipod without need of fluorescent labelling by using Interferential Nanoscopy in Nano Letters

Long-time expertise of LAI  (in collaboration with CINAM) in Reflection interference contrast microscopy have recently permitted a new advance to perform nanometer scale mapping of the cell lamellipod in vitro. Combining multicolor RICM with in silico reconstruction and using optical modeling, the topography of the upper and lower membrane of a lamellipod was reconstructed, as well as the refractive index mapped. These measurements were successfully compared with independent determinations using Atomic Force Microscopy or Quantitative Phase Imaging which both provide only a partial information.

New Doc2AMU PhD Candidate accepted in LAI!

Farah Mustapha (Faculté de Sciences, rafic hariri, Lebanon) was selected by Doc2AMU program for a 3-year PhD funding on “Smart Interrogation of Mechanosensing in T cell Activation” with Pierre-Henri Puech and K.Sengupta (CINaM) as co-advisors. she will join in October the lab. Congratulations !

LAI welcomes Aya Nassereddine as a PhD student

We welcome Aya Nassereddine, from Lebannon. After a master in immunology in Luminy, Aya has started her PhD under the direction of Kheya Sengupta (CINAM) and is now also coadvised by Laurent Limozin in LAI. She is preparing original transparent nanopatterned substrates and use them to study lymphocyte physiology with live microscopy.

Have a great time!
