“Materials innovations towards developing miniaturized diagnostics platforms”


In this talk, I will discuss a new class of benchtop fabrication method for developing materials that are structurally and functionally tunable for addressing the needs of the field of biosensing. In biosensing, it is often required to develop materials that are optimized over multiple length scales: nanoscale features are required for optimal display of nanoscale biorecognition agents, whereas, microscale sensing elements ensure that a sufficient number of target analyte interact with the biosensor surface in clinically-relevant times. The benchtop method developed here is based on a combination of self-assembly, substrate-induced thin film wrinkling, and pattern transfer for creating tunable hierarchical structures on flexible substrates. Throughout this talk, I will present multiple examples to demonstrate how these materials enhance the performance of biosensors that detect nucleic acids, proteins, and small molecules. Finally, I will present an example of a clinical diagnostic system that is developed based on these innovative materials.

STUDENTS – after the talk, you’re encouraged to return to the 2nd floor Atrium lounge to meet with the speaker.
COFFEE – coffee and cookies will be available in the 2nd floor Atrium lounge at 1:15 p.m.
CELL PHONES – as a courtesy to the speaker and audience, please set your cellphones to “silent” mode. Thanks!
