    The paper presents a comparative study of currently available techniques and methods of microparticle transport and separation control. Intense studies of biological objects have required new effective means for nondestructive action upon particles in liquids using external fields. The up-to date techniques applicable to mi-croanalytical instruments and devices are considered.
