According to one embodiment, provided is a single particle analyzing device including a measuring vessel, first and second chambers in the vessel defined by an insulating membrane, a pore opening in the membrane to connect the chambers, and first and second electrodes in the chambers. Electric current flows between the electrodes through the pore. Electrical characteristics are measured during migration of the target from the first chamber to the second chamber to measure the size and shape of the target. (a) t&#x3c;a &#x3c;d&#x2266;100or (b) s&#x3c;L, s&#x3c;d&#x2266;100, t&#x3c;L and t&#x3c;d, wherein a, L and s are the diameter, length and width of the target, d is the diameter of the pore, and t is the thickness of the membrane in the proximity to the pore.

The present invention provides a method and apparatus for controlling the moving speed of a substance, both of which can adjust the moving speed of a substance to a desired speed. The control method and control apparatus cause a substance to pass through an internal space, in which an electro-osmotic flow is generated, of a surround electrode formed so as to surround part of the moving path of the substance, whereby the control method and control apparatus change the moving speed of the substance.
