Figure 2 - Sulfur-containing compounds for gold surfaces

Figure 2: Commonly used sulfur-containing compounds used for attachment to gold surfaces such as quantum dots.

Thioctic acid (also known as lipoic acid), cystamine, 2-mercaptoactic acid, and 2-mercaptoethylamine (MEA) are common sulfur-containing compounds used for attachment of hydrophilic groups to gold surfaces such as those found in quantum dots.
