The present communication describes the synthesis of gold nanoparticles (AuNPs) using 1-amino-2- naphthol-4-sulphonic acid (ANSA) with enhanced stability. The method of preparation is similar to the conventional method using sodium citrate as reducing agent. Briefly, ANSA was quickly added to a boiled solution of hydrogen tetrachloroaurate under stirring, resulting in the synthesis of deep red-coloured AuNPs. The AuNPs prepared by ANSA (AuNPs-ANSA) exhibit twofold increase in stability towards sodium chloride over those prepared by sodium citrate. AuNPs-ANSA are 35.1 nm in size and particles has various shapes, viz. hexagonal, pentagonal, spherical, etc. AuNPs-ANSA can be functionalized with immunoglobulins and functionalized nanoparticles exhibit flow properties in lateral-flow assay.
