Studying Fluorescence in Bio-Inspired Materials for Sustainability

The student scholars in the Molecular Engineering lab will be the first to study a previously undiscovered fluorescence property in a well-researched material, with applications as a sensor for detecting contaminants in water. This new fluorescence feature is an exciting discovery in a material, called peptide amphiphiles (PAs), that already has some amazing features such as (1) using precision synthesis to allow researchers to exactly control the molecular structure and (2) spontaneously self-assembling in water into ordered macro-scale structures called micelles. PA micelles have been used for important applications like resource recovery from water, nerve regeneration, and tissue scaffolding.

However, despite being well studied for the past 2.5 decades, no one had reported that PA micelles are intrinsically fluorescent. Until now! It also turns out that when PA micelles bind to a target molecule, the fluorescence signal gets amplified, so they are stimuli-responsive too! All of these features make PA micelles a very intriguing platform to detect emerging contaminants in water - a technology that is desperately needed in the water crisis, especially in low-to-middle-income countries.

To work towards the end goal of designing effective sensors, we first need to understand this fluorescence and learn how to optimize the signal. Students scholars on this project will design PA molecules and their self-assembled micelles to uncover which features optimize the intrinsic fluorescence.
