Preparation and stabilization of monodisperse colloidal gold by reduction with aminodextran

Synthesis and characterization of nano-sized ɛ-Zn(OH)2 and its decomposed product, nano-zinc oxide

“…The material shows nano-sized spheres with diameters of about 50 nm. The crystallite size calculated using the Debye-Scherrer's formula for the material (∼33 nm) is very close to their observed size by TEM, suggesting that -Zn(OH) 2 nanoparticles are single crystals [21,22].…”

Functionalized gold nanoparticles for 2-naphthol binding and their fluorescence properties

“…2) characteristic of spherical AuNPs was observed at = 539 nm when the aurate anions were reduced in the presence of ␤CD-(SH) 2 molecules, while the plasmon maximum appeared at = 519 nm without cyclodextrin. The absorption band at = 520-550 nm corresponds to the plasmon band of AuNPs and confirms the presence of gold nanoparticles in the dispersions [24][25][26][27]. The surface modification of AuNPs reduced in the presence of ␤CD-(SH) 2 resulted in linked structure and a 20 nm shift of the plasmon band maximum (Fig.…”

Preparation of Nanosilver and Nanogold Based on Dog Rose Aqueous Extract

“…Here, attention should be paid to the mechanism of the reduction process occurring in the reaction within the mixtures of different pH values. Referring to the literature data [40] the structure of the complex ions derived from the chloroauric acid depends on the number of hydroxyl ions present in the mixture. Its form depends on the pH value, which is shown in Table 7.…”
