Abstract
Embodiments of the present invention described herein provide a device that can measure a single particle in flow several times along a microchannel with integrated waveguides that carry optical signals (e.g. excitation, emission, transmission, and scattered light) to and from measurement regions. Embodiments of the present invention used to perform multiple measurements of particles, such as microspheres or cells, traveling in a sample fluid through a microfluidic channel achieve lower uncertainties, discriminate complex samples, and account for sources of uncertainty that might be related to the shape, deformability, stability, or activity of objects in a liquid sample.
