In the past decade, quantitative phase imaging gave a new dimension to optical microscopy, and the recent extension of digital holography techniques to nonlinear microscopy appears very promising, for the phase of nonlinear signal provides additional infor ...
We demonstrate focusing coherent light on a nanoparticle through turbid media based on digital optical phase conjugation of second harmonic generation (SHG) field from the nanoparticle. A SHG active nanoparticle inside a turbid medium was excited at the fu ...
The formation of complexes between nanoparticles and polyelectrolytes is a key process for the control of the reactivity of manufd. nanoparticles and rational design of core shell nanostructures. In this work, we investigate the influence of the nanopartic ...
Well-defined and perfectly dispersed [(square SiO)Au(1)] surface species supported on silica have been obtained via surface organometallic chemistry and transformed upon mild reduction (H(2), 300 degrees C) into small (1.8 +/- 0.6 nm) Au particles supporte ...
Functionalized nanoparticles (NPs) are presently under intensive study aimed at creating useful tools for molecular diagnosis, therapy, and biotechnology. ...
The solar-to-elec. power-conversion efficiency (η) of dye-sensitized solar cells can be greatly enhanced by integrating a mesoporous, nanoparticle-based, one-dimensional photonic crystal as a coherent scattering layer in the device. The photogenerated curr ...
Nanostructures displaying fluorescence and magnetic properties at the same time are potentially useful for achieving simultaneous bio-sepn. and bio-sensing (e.g., magnetic sepn. coupled with multiplexing optical detection of different tumor cell population ...
This thesis mainly deals with the integration of a microfluidic system for the extraction of micrometric and submicrometric particles from a solution. Traditional methods take from several minutes to hours to separate particles from a solution. Microfluidi ...
The solubility of alkylthiol-coated silver nanoparticles and the energetics of the ligand disordering have been investigated. Calorimetry measurements have provided correlations between the nature of the ligands and the enthalpy of the ligand disordering, ...
Colloidal Ag nanoparticles were formed by X-ray irradiation in the presence of a polymer. This new synthesis method is simple, rapid and leads to a high production yield. Compared to the citrate-reduced Ag colloidal, polymer-protected Ag nanoparticles are ...
