In this paper, we have described the size-controlled synthesis of gold nanoparticles based on the reduction of Au3+ (HAuCl4 ) using molybdophosphoric acid (H3[PMo12O40 ], HPMo) under UV-irradiation. In the process, HPMo plays the role of photocatalyst, reducing agent and stabilizer and propan-2-ol acts as a sacrificial agent. This method allows the synthesis of uniform hexagonal nanoparticles w...

Conventional microbiology methods used to detect bacteria include multiple cultures and identification processes, so the results of lab work are painstaking and time-consuming. In recent years, more and more tend to use the diagnostic tests which are based on DNA; hence, DNA diagnostic biosensors have been created to perform DNA identification better. In this study, GUS and hpt genes were used ...

Biocompatible materials used for the fabrication of dental crowns were studied. Patients were treated with Gold, Porcelain and Zirconia crowns. Dental crowns were selected according to patient’s clinical status and needs. We found that Gold crowns had low patient acceptance because of poor aesthetics and high cost. Gold crowns could not be used opposite to amalgam restorations for the fear of g...

Gold nanoparticle-based diagnostic methods have attracted much attention due to their simplicity, high sensitivity and low cost. These methods are mostly used for early and efficient detection of various pathogenic factors and assessment of gene expression and nanoparticles stability. In this study, melon plants were cultured in vivo and then, RNA was extracted from leaf explants. A 40 bp probe...
