Basic Single Particle Measurements
Direct measurements of forces acting on a microparticle are made by using the dc field of an electrostatic balance or an electrodynamic balance to counteract any vertical applied force, the most obvious force being gravity. But numerous other forces are o

Foreword
It has been thirty years since one of the authors (EJD) began a collaboration with Professor Milton Kerker at Clarkson University in Potsdam, New York using light scattering methods to study aerosol processes. The development of a relatively short-lived commercial particle levitator based on a modification of the Millikan oil drop experiment attracted their attention and led the author to the study of single droplet s and solid microparticles by levitation methods . The early work on measurements of droplet evaporation rates using light scattering techniques to determine the size slowly expanded and diversified as better instrumentation was developed , and faster computers made it possible to perform Mie theory light scattering calculations with ease. Several milestones can be identified in the progress of single microparticle studies. The first is the introduction of the electrodynamic balance, wh
