Gold nanoparticles (AuNPs) stabilized by imidazolium salts derived from amino acids [glycine (<b>1</b>), <i>rac</i>-alanine (<b>2</b>), l-phenylalanine (<b>3</b>), and <i>rac</i>-methionine (<b>4</b>)] were prepared. The AuNPs were stabilized the most by <b>4</b>, which kept the particles dispersed in water for months at pH > 5.5. These AuNPs exhibited a well-defined absorption band at 517 nm and had an average particle size of 11.21 ± 0.07 nm. The 4-AuNPs were reversibly aggregated by controlli ...[more]
