Research in the Perry laboratory utilizes self-assembly, molecular design, and microfluidic technologies to generate biomimetic microenvironments to study and enable the implementation of biomolecules to address real-world challenges. Individually, microfluidics represents an enabling technology for high throughput analyses such as the time-resolved structural analysis of enzyme dynamics or the continuous manufacture of RNA. At the same time, control over molecular interactions in self-assembling polyelectrolyte systems can be used to examine the interplay between biomolecules and the environment. Together, these capabilities can be coupled to generate artificial organelles for use in applications ranging from biochemistry to bioenergetics, biocatalysis, and biomedicine. Furthermore, this work has tremendous pedagogical potential to inspire students to work at the intersection of chemistry, biology, and engineering.
