news: original paper on hydrogel encapsulation crystalline colloidal arrays (CCA) sees increase in citations

The original Langmuir publication (Langmuir 2001, 17, 19, 6023-6026) on the technique developed in the Foulger Group back in 2001 for the hydrogel encapsulation of crystalline colloidal arrays (CCA) has received a number of recent citations. These photonic crystals have seen a surge in interest from the scientific community, such as this recent publication in ACS Nano that is based on our prior work. "Mechanochromic response of poly(ethylene glycol) methacrylate hydrogel encapsulated crystalline colloidal arrays" describes how electrostatic stabilized polystyrene arrays of approximately 100 nm particles can be encapsulated in a polyethylene-oxide hydrogel to stabilize the arrays from mechanical and ionic disturbances that would destroy the crystal. This technique has been adopted by a number of groups to produce robust films from the delicate arrays.
