Bacteriophages possess the fundamental properties of viruses, yet exhibit ease of assay, handling, and culture, and thus present suitable systems for isotope tracer studies of the mode of virus reproduction and protein synthesis. In an investigation of this problem we have employed the Escherichia coli bacteriophage Ta system. This communication outlines methods for the growth and isolation of ...

PURPOSE The aim of the present study was preparation, physicochemical characterization and performance evaluation of gold nanoparticles (GNPs) in radiotherapy. Another objective was the investigation of anti-bacterial efficacy of gold nanoparticle against E. coli clinical strains. METHODS Gold nanoparticles prepared by controlled reduction of an aqueous HAuCl4 solution using Tri sodium citrat...
