Article Synopsis
- The study focuses on the synthesis of nanostructured calcium phosphates, specifically nanohydroxyapatite (HAP) with varying silicon content, through aqueous precipitation and calcination.
- The materials were characterized using various techniques, including XRD and FTIR, which confirmed the presence of HAP and β-TCP phases, alongside nanocrystalline features, and highlighted changes due to silicon and calcination temperatures.
- The scaffolds created from these materials showed improved cell adhesion and proliferation in human osteoblast cultures, indicating their potential for use in bone reconstruction applications.
The effect of arginine on gold nanoparticles in colloidal solutions and in thin films.
J Nanosci Nanotechnol
September 2011
Gold nanoparticles were prepared in aqueous colloidal solutions and their interaction with L-arginine solutions at different concentrations was investigated by UV-vis spectroscopy, transmission electron microscopy (TEM) and atomic force microscopy (AFM). The shift towards red of the absorption maximum of gold nanoparticles with increasing L-arginine concentration and in time, and the apparition of a new large band at higher wavelength evidence the formation of assemblies of gold nanoparticles, mediated by the amino acid. TEM images present the progress in the building process of supermolecular structures.
