Heatmap depicting correlation between precursors and resultant AuNP morphologies. The heat illustrated in a given cell represents the fraction of morphologically-targeted articles (say, the fraction of sphere-related articles) which use that particular precursor among one or more precursors it uses in the recipe. For instance, the top left cell shows that more than 90% of purely sphere-related AuNP synthesis papers use \({\rm{A}}{\rm{u}}{\rm{C}}{{\rm{l}}}_{4}^{-}\) as a precursor. “Citrate” also includes sodium citrate precursors. The entire heatmap describes 1,511 single morphology-targeted articles with at least one of the precursors or precursor ions shown on y-axis.
