Abstract: Certain disclosed embodiments concern an integrated imaging system that combined light-sheet microscopy, which enables considerable speed and phototoxicity gains, with quantitative-phase imaging. A method for using such imaging systems also is disclosed. In an exemplary embodiment, an integrated imaging system was used for multivariate investigation of live-cells in microfluidics.

Abstract: A sensor, system, and method of making a sensor are disclosed. The sensor includes a solid polymer material, and a dopant-containing region of discrete thickness at a surface of the solid polymer. The method of creating the sensor includes impregnating the polymer material with the dopant by contact with a solvent solution containing the dopants. A polymer/solvent gel-layer, whose depth increases with impregnation time, forms after contact of the polymer material in the solvent solution. The dopants are diffused into the polymer material, forming a dopant-containing region of discrete thickness at a surface of the solid polymer.
