چکیده مقاله:
Preparation of gold nanoparticles has attracted a great deal of interest due to their interesting optical properties and potential in biomedical applications. For this purpose, one challenge is to find a non-toxic chemical and/or physical method for functionalizing gold nanoparticles with biomolecule compounds. In the current study, a new microemulsion system composed of tetraocthyl ammonium bromide was introduced and studied in details. By using this microemulsion system a novel methodology was applied to prepare biocompatible gold clusters protected by a monolayer of monohydroxy thioalkylated PEG ligand. The morphology, size and size distribution of the prepared functionalized gold nanoparticles were obtained by different methods including dynamic light scattering (DLS), UV-visible spectrophotometry and transmission electron microscopy (TEM).
