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 ...
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 ...
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 ...
Control of silver nanoparticles characteristics using a dedicated nano-clusters source and wavelength tuning of Plasmon resonance generated by small nanoparticles using different matrices. The results have been validated by advanced surface Plasmon modelin ...
Functionalized nanoparticles (NPs) are presently under intensive study aimed at creating useful tools for molecular diagnosis, therapy, and biotechnology. ...
We explored a very interesting gold nanoparticle system-pegylated gold in colloidal solution-and analyzed its uptake by mice colorectal adenocarcinoma CT26 tumor cells and the impact on the cell's response to x-ray irradiation. We found that exposure to po ...
It is well known that the electrostatic repulsions between charges on neighboring sites decrease the effective charge at the surface of a charged nanoparticle (NP). However, the situation is more complex close to a dielec. discontinuity, since charged site ...
A nanomosaic network of metallic nanoparticles for the detection of ultralow concentrations of proteins is reported, which uses two planar microelectrodes embedded in a microchip that permit generation of capacitive coupling to the nanomosaic system withou ...
In this study, the application of reaction calorimetry, an efficient tool to obtain kinetic and safety data, is presented on the free radical dispersion polymn. of MMA in scCO2. The effect of three major parameters with respect to the reaction evolution ar ...
Increasing interest in specific applications in the field of micro- and nano-electromechanical systems (MEMS and NEMS) has raised the request for new functional polymeric materials. Epoxy based photoresists are being broadly used for the fabrication of mic ...
