Synthesis of thiol-derivatised gold nanoparticles in a two-phase liquid-liquid system
TLDR
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.Abstract:

Formation and Structure of Self-Assembled Monolayers.
TL;DR: Monolayers of alkanethiolates on gold are probably the most studied SAMs to date and offer the needed design flexibility, both at the individual molecular and at the material levels, and offer a vehicle for investigation of specific interactions at interfaces, and of the effect of increasing molecular complexity on the structure and stability of two-dimensional assemblies.

The Bakerian Lecture: Experimental Relations of Gold (and Other Metals) to Light
TL;DR: The undulatory theory of light, with the phenomena for which it strives to account, seems to me, who am only an experimentalist, to stand midway between what we may conceive to be the coarser mechanical actions of matter, with their explanatory philosophy, and that other branch which includes, or should include, the physical idea of forces acting at a distance as mentioned in this paper.

A new hydrosol of gold clusters
TL;DR: In this article, the reduction of gold(III) ions by tetrakis(hydroxymethyl)phosphonium chloride gives a hydrosol of gold clusters with mean diameter 1.5 nm (average nuclearity about Au170) and smaller.
