An antibacterial coating based on a polymer/sol-gel hybrid matrix loaded with silver nanoparticles
In this work a novel antibacterial surface composed of an organic-inorganic hybrid matrix of tetraorthosilicate and a polyelectrolyte is presented. A precursor solution of tetraethoxysilane (TEOS) and poly(acrylic acid ... -
An antibacterial surface coating composed of PAH/SiO2 nanostructurated films by Layer by Layer
In this article we propose a novel antibacterial coating composed of SiO2 and the polymer Poly(allylamine hydrochloride) (PAH) on glass slides by the technique Layer-by- Layer (LbL)1. This technique has already used in ... -
A comparative study in the sensitivity of optical fiber refractometers based on the incorporation of gold nanoparticles into layer-by-layer films
In this work, optical fiber refractometers based on the successive incorporation of gold nanoparticles have been fabricated by means of the Layer-by-Layer Embedding (LbL-E) deposition technique. This enables the apparition ... -
A comparative study of two different approaches for the incorporation of silver nanoparticles into layer-by-layer films
In this work, a comparative study about the incorporation of silver nanoparticles (AgNPs) into thin films is presented using two alternative methods, the in situ synthesis process and the layer-by-layer embedding deposition ... -
