STUDY ON FABRICATION OF THE COLLOIDAL SOLUTION BASED ON HIGH QUALITY SILVER NANOPARTICLES TO ANTIFUNGAL ACTIVITY APPLICATION

Abstract

In this paper, Ag nanoparticles ( Ag NPs) were successfully fabricated by the chemical reduction
method using tert-butylamine borane complex in the organic solvent at room temperature in which
poly(maleic anhydride-alt-1-octadecene) (PMAO) was used as the phase transfer ligand. TEM images
show that Ag NPs with the average size below 10 nm were formed. The morphology, size and properties
of Ag NPs were controlled by varying reaction time. Result shows that the after encapsulated by
poly(maleic anhydride-alt-1-octadecene) (PMAO), the surface of Ag NPs becomes hydrophilic and
well-dispersed in water for at least 12 months. The colloidal silver solution presented considerable
antifungal activity performance against Aspergillus glaucus. These findings suggest that the silver
solution has potential for clinical applications.
