SPIE Photonics West Proceedings 2
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
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
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.
