Abstract
A multi-phase system includes a phase-separated solution comprising at least two phases, each phase having a phase component selected from the group consisting of a polymer, a surfactant and combinations thereof, wherein at least one phase comprises a polymer, wherein the phases, taken together, represent a density gradient. Novel two-phase, three-phase, four-phase, five-phase, or six-phase systems are disclosed. Using the disclosed multi-phase polymer systems, particles, or other analyte of interest can be separated based on their different densities or affinities.
