 “Innovations of precise macromolecules: Catalysis, high throughput, and bio-applications.”

Proteins contain discrete primary sequences that lead to defined chemical structures through precise supramolecular folding and assembly. In contrast, synthetic macromo­lecular materials are typically polydisperse with a random sequence and with poorly de­fined structures. Achieving better control of polymer structures offers a unique opportu­nity to better understand the structure-activity relationship of the materials and enable new applications. In this talk, we will see how folded single-chain polymer nanoparticles can have similar functions to protein scaffolds in developing artificial enzymes. In ad­dition, I will discuss multiple strategies to prepare precise macromolecules, including a high throughput method to develop libraries of discrete oligomers, and how these lead to novel and safer biomaterials. These results underscore the versatile impact that the polymer structure can have on the design and functions of materials, especially in bio­logical applications.
