CNRS INSIS Highlights 2010

21 Avril 2010 , Rédigé par JW Publié dans #Recent research work

Our endoscope system to detect and analyse single molecule fluorescence has recently been highlighted by the CNRS Institute for Engineering and Systems Sciences. See the article here. (French only, sorry). Another description (in English) can be found in a previous article on this blog.

The Master for Photonics Engineering, Nanophotonics and Biophotonics aims at giving an extensive two-year teaching program from fundamentals to advanced research topics in Photonics and its interdisciplinary applications.

 

 

The application for European Union students is currently open. See the link here.

 

 

What are the advantages of this program ?

  • state-of-the-art teaching on truly modern photonics (not 19th century physics)
  • prestigious Erasmus Mundus EU program 
  • Up to 10 000 € / year scholarship
  • International culture exchange among students (20 students selected, 8 from EU and 12 non-EU).
  • Experience the boiling student ambiances of Marseille, Karlsruhe and Barcelona

In one sentence : get best teaching, money & warm atmosphere. What do you expect more ? Apply NOW !

SPIE Photonics West Proceedings 2

2 Avril 2010 , Rédigé par JW Publié dans #Recent research work

Following in SPIE Photonics West conference in last January, we have a second proceedings paper published. This one corresponds to an invited contribution.

 

Enhanced fluorescence from metal nanoapertures: physical characterizations and biophotonic applications
J. Wenger, H. Aouani, D. Gérard, S. Blair, T.W. Ebbesen and H. Rigneault Proc. of SPIE, Proc. SPIE Vol. 7577, pp.75770J (2010)

 

A personal reprint can be found here.

 

The major contribution of this proceedings paper is to provide with the most general figures to predict the fluorescence enhancement factors by nanoapertures for almost every kind of fluorescent molecule. This knowledge is essential to discuss the ability to detect low-quantum yield species.

 

We also report of the following new results :

- detailed physical characterization of this phenomenon for apertures milled in gold and aluminum

-  first demonstration of single metal nanoapertures to perform DNA hybridization sensing

SPIE Photonics West Proceedings 1

2 Avril 2010 , Rédigé par JW Publié dans #Recent research work

Following in SPIE Photonics West conference in last January, we have a proceedings paper published.

 

High-efficiency single molecule fluorescence detection and correlation spectroscopy with dielectric microspheres
H. Aouani, N. Djaker, J. Wenger, and H. Rigneault, Proc. of SPIE, Proc. SPIE Vol. 7571, pp.75710A (2010)

 

A personal reprint can be found here.

 

We report of the following new results :

- microspheres made of high refractive index melamine resin provide a seven-fold fluorescence enhancement on single molecules.

- this effect can be used to increase the signal-to-noise ratio in fluorescence correlation spectroscopy and reduce the experiment integration time by fifty-fold.

- first description of dual-color fluorescence cross-correlation spectroscopy (FCCS) enhanced by a microsphere.

My first article in Micscape

28 Mars 2010 , Rédigé par JW Publié dans #Fancy lab

For those of you who do academic research on (nano)photonics but don't know about the Micscape journal, then you're definitely missing one of the major publications about microscopy It's loaded with plenty of useful / interesting / futile* stuff (* choose the word that best applies to what you're looking for).

Going back to basics, my first Micscape paper is thus devoted to an early student microscope stand of the second mid of the 19th century. Thanks to its open design, this microscope is ideal for demonstrations, and also for oblique epi-darkfield illumination to reveal physical colors from diatoms.
