Abstract:The goal of the current study is to show how to use green synthesis to create gold nanoparticles, and present a method to determine the dielectric constant of nanoparticles solutions that are used in optical biosensing applications. Green tea (Camellia sinensis) leaf extract was used as a reducing agent to obtain nanoparticles. The gold nanoparticles were synthesized for different concentrations of green tea, directly impacting the particle's size and refractive index. The experimental data from the absorption… Show more
