Abstract

This study aimed to examine the effects of α-cyclodextrin and β-cyclodextrin as stabilizing agents on gold nanoparticles (AuNPs) reduced by o-hydroxybenzoic acid. Comparative studies were carried to compare the size of AuNPs after the addition of stabilizing agents. The optimization was done under stabilizing agent concentration. AuNPs with α-cyclodextrin and β-cyclodextrin were optimum at 0.040 M stabilizing agent. DLS analysis showed that after the addition of α-cyclodextrin and β-cyclodextrin as stabilizing agents, the size of AuNPs decreased. This result indicated that AuNPs, added with α-cyclodextrin and β-cyclodextrin had better stability and increase the uniformity of AuNPs.
