ABSTRACT Chemical methods allow an easy synthesis of silver nanoparticles in solution. These metal nanoparticles have a great potential for biomedical applications as antibacterial agent, antifungal, antiviral or wound healing. The modification of the parameters involved in these reactions permits a precise control over the size, the shape, the monodispersity and the surface of the nanoparticles. The organometallic method meets these requirements giving rise to small silver nanoparticles with a high antibacterial activity. Los métodos de síntesis química en disolución permiten la síntesis de nanopartículas de plata de manera sencilla. Estas nanopartículas metálicas poseen un gran potencial en aplicaciones biomédicas como agente bactericida, fungicida, antiviral o cicatrizante. La modificación de los parámetros involucrados en estas reacciones en disolución conducen a un control preciso sobre el tamaño, la forma, la monodispersidad y la superficie de estas nanopartículas. El método organometálico cumple todos estos requisitos dando lugar a nanopartículas de plata de tamaño pequeño con una alta capacidad bactericida.

    ABSTRACT: This paper presents the formation of nanosized metallic particles synthesized in sodium bis(2-ethylhexyl)sulfosuccinate (AOT) reverse micelles in compressed propane and supercritical fluid (SCF) ethane solutions. Silver nanoparticles were produced in AOT reverse micelles in compressed propane by the reduction of the silver salt, AgNO 3 . Copper nanoparticles were produced in compressed propane and SCF ethane solvents, with added isooctane cosolvent, by the reduction of the functionalized surfactant, Cu(AOT) 2 . Particle growth rates in the compressed fluids are compared with those in normal liquid solvents to illustrate the effects of the compressed fluids on the growth behavior of these nanoparticles within the reverse micelles. The metallic nanoparticles were characterized using both in situ UV-vis spectroscopy and transmission electron microscopy. The use of compressed fluids and SCFs for nanoparticle formation in AOT reverse micelles can result in growth rate behavior different from that in normal liquid solvents for both copper and silver. This is the result of the intermediate physical and transport properties of the compressed and supercritical solvents which lead to enhanced collision frequencies and exchange rates between micelles.

    ABSTRACT: A simple method is used to prepare highly monodispersed silver nanoparticles in the liquid phase, which starts from an initial synthesis in functionalized AOT reverse micelles. To narrow the particle size distribution from 43 to 12.5% in dispersion, the particles are extracted from the micellar solution. The size-selected precipitation method is used. The nanocrystallites dispersed in hexane are deposited on a support. A monolayer made of nanoparticles with spontaneous compact hexagonal organization is observed. The immersion of the support on the solution yields to the formation of organized multilayers arranged as microcrystal in a face-centered-cubic structure. We compare the optical properties of spherical particles organized in a two- and three- dimensional structure with isolated and disordered particles. When particles, deposited on cleaved graphite, are arranged in a hexagonal array, the optical measurements under p-polarization show a new high-energy resonance, which is interpreted as a collective effect, resulting from optical anisotropy due to the mutual interactions between particles. We support this interpretation by numerical calculations performed for finite-size clusters of silver spheres. For disordered particles, a low-energy resonance appears instead of the high-energy resonance observed for spherical and organized particles. This is interpreted as optical shape anisotropy due to the asymmetrical arrangement of particles. The tip of a scanning tunneling microscope (STM) may be used as an extremely localized source of low-energy electrons to locally excite photon emission from a variety of metal films. The detection of locally excited luminescence at the junction of an STM tip provides access to electron dynamic properties at the surface, which makes it possible to study luminescence phenomena of nanometer-sized structures. The photon intensity emitted from electrically isolated silver nanoparticles self-organized as a 2D network on a gold (111) substrate is analyzed. We observed unexpectedly strong variations of photon-emission efficiency from isolated nanoparticles, depending on how tightly they are embedded within the network site. The quenching site observed in the STM photon emission map is interpreted as an enhanced interaction of electrons with surface photon modes.
