background: cystic echinococcosis is an important zoonosis caused by the echinococcus granulosus with a substantial impact in human and animal health in en-demic areas. the purpose of the present study was serodiagnosis optimizing of dog echinococcosis in order to achieve a rapid diagnostic method. methods: eight dogs were challenged with protoscoleces in order to have posi-tive echinococcosis ...

Background With gold nanoparticles (AuNPs) is possible to develop nanoscale devices that can interact with chemical and biological systems. The phenomenon explored in these nanosystems is called Localized Surface Plasmon Resonance (LSPR), which promotes electromagnetic wave oscillation electronics on these small metallic structures. It is interesting to note that this resonance is directly link...

The fabrication of a coffee ring was studied in this work to improve its sensitivity detecting trace analytes based on surface-enhanced Raman scattering (SERS). Gold nanoparticles were synthesized with diameters ~40 nm through the sodium citrate reduction method, and rhodamine 6G (R6G) employed as probe evaluate performance fabricated rings. results showed that formed from water-washed gold pre...

The aim was to assess the technological feasibility of generating sodium cyanide by coal gasification, study effects process parameters (temperature, experiment duration, type) on concentration in resulting solutions, as well identify optimal modes process. Experiments were carried out a laboratory setup consisting tubular cylindrical furnace equipped with working compartment form corundum tube...

In this contribution, we report on the simulation of optical reflectance and transmittance (R&T) taken a set gold nanoparticles thin film, deposited sodium alginate by magnetron sputtering. The layer is very thin, so that films are not continuous material arranged in nanostructured layers. R&T spectra simulated using Generalized Transfer Matrix method applied to film-on-substrate model....
