Controlled nucleation for the regulation of the particle size in monodisperse gold suspensions
TL;DR: In this article, a series of monodisperse suspensions of the same chemical composition but of rather different particle sizes was used to study particle size dependent phenomena, such as Brownian motion, light scattering, sedimentation and electrophoresis of small particles.

A study of the nucleation and growth processes in the synthesis of colloidal gold
TL;DR: In this paper, a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids, and it was shown that nucleating agents may be identified with reducing agents which form a mixed polymer with chlorauric ion before the reduction to the nucleus takes place.

Synthesis of thiol-derivatised gold nanoparticles in a two-phase liquid-liquid system
TL;DR: Using two-phase reduction of AuCl4 by sodium borohydride in the presence of an alkanethiol, solutions of 1-3 nm gold particles bearing a surface coating of thiol have been prepared and characterised; this novel material can be handled as a simple chemical compound as mentioned in this paper.
