Silver nanoparticles were synthesized in linear and branched polyelectrolyte matrices using different reductants and distinct synthesis conditions. The effect of the host hydrolyzed linear polyacrylamide and star-like copolymers dextran-graft-polyacrylamide of various compactness, the nature of the reductant, and temperature were studied on in situ synthesis of silver sols. The related nanosyst...

The purpose of this study was to synthesize duloxetine (DLX)- loaded Eudragit-Chitosan (Eud-CHT) nanoparticles enclosed in an oral gelatin capsule and evaluate the potential transport DLX blood-brain barrier (BBB)for improved neuro-availability. utilization Eudragit® with chitosan offers a pH-dependent controlled drug release. physicochemical properties formulated DLX-loaded Eud-CHT nanosystem ...

Santos, Wenguo Cui, and co-workers construct a light-controlled nanosystem with in situ modulated particle size by near-infrared irradiation synergistic effect using photochemotherapy for tumor suppression. The at the leads to rapid shedding of polye thylene glycol enhanced cellular uptake. versatile design this flexibility opens new avenues cance...

The use of high-pressure for the study and elaboration of homogeneous nanostructures is critically reviewed. Size effects, the interaction between nanostructures and guest species or the interaction of the nanosystem with the pressure transmitting medium are emphasized. Phase diagrams and the possibilities opened by the combination of pressure and temperature for the elaboration of new nanomate...

One of the main problems in nanoplasmonics is the active dynamic control of optical local fields. We propose an efficient method to solve this problem. It allows one to impose coherent control of the spatiotemporal localization of the optical excitation energy in nanoplasmonic systems on the nanometer spatial and femtosecond temporal scales. This approach is based on a general idea of time reve...

We describe the unique possibility of concentrating the energy of an ultrafast excitation of a nanosystem in a small part of the whole system by means of coherent control (phase modulation of the exciting ultrashort pulse). Such concentration is due to dynamic properties of surface plasmons and leads to local fields enhanced by orders of magnitude. This effect exists for both ‘‘engineered’’ and...

We present a new methodology, based on a combination of genetic algorithms and image morphometry, for matching the outcome of a Monte Carlo simulation to experimental observations of a far-from-equilibrium nanosystem. The Monte Carlo model used simulates a colloidal solution of nanoparticles drying on a solid substrate and has previously been shown to produce patterns very similar to those obse...
