Figure 3. Colloidal crystal-templated synthesis of patchy particles.

Figure 3

(A & B) Patchy particles can be formed by filling a well with a colloidal crystal iteratively, (C) then forming a polydimethylsiloxane (PDMS) mask by adding PDMS solution. (D) As dewetting occurs at the interface between particles, PDMS patches form at the contact points. The particles can be (E) separated from the scaffold and (F) two different proteins can be added by adding the first protein to the exposed region (green) followed by removal of the mask and addition of a second protein (red).
