The kinetics of the synthesis reactions were monitored every 30 min using 2 mL of each sample, undiluted, using a UV/Vis spectrophotometer (UV1800PC, Phenix, Blomberg, Germany), adjusting the wavelength to 450 nm during the incubation period of the colloidal suspensions and experimental controls. In addition, spectrophotometric analyses in the 350 to 500 nm range were conducted at the end of the reactions and seven and thirty days after the initial synthesis to explore the maximum absorption bands of each AgNPs colloidal suspension.
