Paper Abstract
A novel method for rapidly synthesized Au colloidal under microwave irradiation was present in this paper. Size of the
Au nanoparticles varied from 10 nm to 60 nm along with varying mol fractions by chloroauric acid solution reduced with
sodium citrate. The prepared Au nanoparticles were characterized by transmission electron microscope (TEM) and
ultraviolet-visible (UV-Vis) spectrophotometer. It is found that the nanoparticle size and shape are highly dependent on
the reaction time and the molar ratios of the reducing agent. By the SERS measurements of R6G, 4-MBA and Crystal
violet, this Au colloid is shown to be an excellent SERS substrate with good stability. As the fabrication process of this
SERS substrate is simple and inexpensive, this method may be used in large-scale preparation of substrates that can serve
as an ideal SERS substrate in biomedical application.
