The Leidenfrost nanochemistry synthesis of gold colloids was introduced in this Journal as an advanced method to synthesize gold nanoparticles during an undergraduate nanochemistry research project. When trying to repeat these experiments in the laboratory, we experienced difficulties in the synthesis of the gold nanoparticles since the droplets undergoing the Leidenfrost phenomenon were evaporated without changing color to the distinctive red-purple of gold nanoparticles. Therefore, we would like to suggest an alternative procedure to perform this gold nanoparticle synthesis through the Leidenfrost nanochemistry phenomenon by using honey instead of trisodium citrate and adjusting the pH with sodium hydroxide.
