The formation of ceramic-based materials and composites occurs in nature under mild conditions, aided by a range of organic additives. With this template in mind, Bawazer et al. explored whether a combination of organic molecules could be used to make quantum dot assemblies under similar conditions. To discover the right mix, they turned to combinatorial methods paired with genetic algorithms. The recipes that showed the highest fluorescence intensity became the basis for the next set of experiments. These converged on products that fluoresced after 7 days, and in all three, the same set of four additives was conserved.
