Abstract: Methods, systems, and devices are disclosed for imaging particles and/or cells using flow cytometry. In one aspect, a method includes transmitting a light beam at a fluidic channel carrying a fluid sample containing particles; optically encoding scattered or fluorescently-emitted light at a spatial optical filter, the spatial optical filter including a surface having a plurality of apertures arranged in a pattern along a transverse direction opposite to particle flow and a longitudinal direction parallel to particle flow, such that different portions of a particle flowing over the pattern of the apertures pass different apertures at different times and scatter the light beam or emit fluorescent light at locations associated with the apertures; and producing image data associated with the particle flowing through the fluidic channel based on the encoded optical signal, in which the produced image data includes information of a physical characteristic of the particle.

Abstract: Disclosed are methods, devices, systems and applications for camera-less, high-throughput three-dimensional imaging of particles in motion. In some aspects, a system includes a particle motion device to allow particles to move along a travel path; an optical illumination system to produce an asymmetric illumination area of light in a region of the travel path of a particle that scans over a plurality of sections of the particle at multiple time points while the particle is moving; an optical detection system optically interfaced with the particle motion device to obtain optical signal data associated with different parts of the particle corresponding to the particle's volume during motion in the travel path; and a data processing unit to process the optical signal data obtained by the optical detection system and produce data including information indicative of 3D features of the particle.

Abstract: Methods, systems, and devices are disclosed for studying physical or chemical properties of molecules, and/or interactions between molecules such as protein-ligand interactions. The methods, systems, and devices involve transient induced molecular electronic spectroscopy (TIMES). In some configuration, a microfluidic channel having at least one inlet and at least one outlet is used for holding molecules for analyzing the molecules or interactions between molecules.
