Abstract
Biological samples are inherently heterogeneous, yet traditional biosensing typically relies on ensemble measurements that mask critical information. In this talk, we present several optofluidic platforms that integrate advanced optical detection, microfluidics, and surface chemistry to resolve biological complexities at the single-analyte level. We first introduce an optofluidic platform leveraging Interferential Scattering Microscopy (iScat) for the label-free fingerprinting of cell secretomes at the single-particle level. By implementing a multiplexed digital immunoassay, we extract high-dimensional data with sensitivity reaching the single-protein limit [1]. Furthermore, we incorporate polarization-sensitive detection to enable single-shot retrieval of optical activity images, uncovering spatial chirality variations that are typically invisible to bulk analysis [2]...
