Methods and related aspects for detecting unlabeled biomolecules

Abstract

Provided herein are methods of detecting unlabeled biomolecules. In some embodiments, the methods include disrupting a cell population sufficient to release unlabeled biomolecules from the cell population to produce released biomolecules in which the cell population is disposed on a first inner surface of a chamber that is disposed substantially within a fluidic device and in which the chamber comprises a fluidic material. In some embodiments, the methods also include binding the released biomolecules to a second inner surface of the chamber to produce surface-bound biomolecules, introducing an incident light toward the second inner surface of the chamber concurrent with, and/or after, producing the surface-bound biomolecules, and detecting light scattered by the surface-bound biomolecules over a duration to produce a set of biomolecule imaging data. Related fluidic devices, systems, and computer readable media are also provided.
