Field-flow fractionation is coming of age as a family of analytical methods for separating and characterizing macromolecules, nanoparticles, and particulates. The capabilities and versatility of these techniques are discussed in light of the challenges that are being addressed in analyzing nanometer-sized sample components and the insights gained through their use in applications ranging from materials science to biology.
