Imagine tiny LEGO pieces that automatically snap together to form a strong, flat sheet. Then, scientists add special chemical “hooks” to these sheets to attach glowing molecules called fluorophores.

Associate Professor Gary Baker, Piyuni Ishtaweera, Ph.D., and their team have created these tiny, clay-based materials—called fluorescent polyionic nanoclays. They can be customized for many uses, including advancing energy and sensor technology, improving medical treatments and protecting the environment.

The work is published in the journal Chemistry of Materials.
