11. Appendix 1. Turkevich's method for synthesizing gold colloidal solutions

The principle of gold colloid synthesis is based on the reduction of the HAuCl ₄ salt in solution using citrate

\begin{array}{l} {Au}^{III} + 3 réd \to {Au}^{0} + 3 Ox \\ {n Au}^{0} \to {Au}_{n} \end{array}

In addition to its role as a reducing agent, citrate also acts as a stabilizer (figure
