ANTIBACTERIAL APPLICATION OF SILVER NANOPARTICLES STABILIZED BY RICINOLEIC ACID AND ITS EPOXIED FORM
Silver nanoparticles; Ricinoleic acid; Bactericidal effect; Biospectroscopy
Antibiotic-resistant bacteria are one of the major health challenges. There is a need for the development of new strategies to restrain this dissemination. Silver nanoparticles have been used because its bactericidal effect and its ability in enhance antibiotics effect when used as conjugated. In this work, the synthesis of silver nanoparticles with the ricinoleic acid (AgRA) and its epoxied form (AgERA) were optimized to be applied as bactericidal agents accompanied by Fourier transform infrared spectroscopy. Indicating formation of nanoparticles UV-Vis maxima absorbances of 420 nm were obtained for AgRA and 405 nm for AgERA. The concentration of 0.5 mmol∙L-1 of Ag+ and 20 mmol∙L-1 of the surfactant in the synthesis of AgRA and 0.3 mmol∙L-1 of Ag+ and 20 mmol∙L-1 of the surfactant in the AgERA synthesis. There is a reduction of the 10-day synthesis time of AgRA to 6 h in AgERA. In MET images, the mean nanoparticle size were 16.70 nm for AgRA and 17.80 nm for AgERA.
