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

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.
