title: Dielectrophoretic dynamic light-scattering (DDLS) spectroscopy.
abstract: Dielectrophoretic dynamic light-scattering (DDLS) spectroscopy is presented. DDLS identifies macromolecules based on their dielectric, or polarizability, properties. DDLS measurements are carried out in an oscillating, nonuniform electric field. The field induces macromolecules to undergo dielectrophoretic motion, which is detected by the modulation in the dynamic light-scattering autocorrelation function. The DDLS experimental setup, data analysis, and data on latex particles and yeast cells are presented.
