Graduate students Mingzhu Liu and Veronica Grebe synthesize DNA functionalized dipatchy particles into colloidal superstructures using cooperative depletion and DNA-mediated interactions. The assembly of various superstructures are reported, including flower‐like Kagome, brick‐wall like monolayer, orthogonal packed single or double layers, wrinkled monolayer, and colloidal honeycomb superstructures. The flower-like Kagome and brick-wall like structures are analyzed and quantified using a custom algorithm. The yielded structures can be tuned by changing the patch size of the particle, as well as the assembly conditions. The work contributes an empirical phase diagram, contributes domain knowledge to the design of 2D materials of various superstructures, and is potentially translatable to 3D.
