Characterization of gold nanoparticles. Performed with the optimal size 15 nm. a UV-Vis spectrophotometry analysis. A prominent single peak was found at 550 nm. b Transmission electron microscope observation. Figure inset shows the enlarged image. Scale bar is shown. c Fourier-transform infrared spectroscopy analysis. Apparent peak positions for gold and NH2 are indicated. d Volume distribution analysis of GNP. The obtained distribution is shown. e Zeta potential analysis. The value was found to be − 6.9
