The present invention provides a method for microelectronic positioning
bioparticles, which utilizes dielectric and non-contact electrical force
of cell themselves associated with multi-phase electrical signals to
attain uniformity of distribution of the bioparticles and positioning
thereof within micro-areas in a cell culture system. The obstacle of
system geometrical structure is eliminated so as to simplify the system
layout and programmably change cells' positions. The present method is
suitable for treating cell array in a large quantity. The present method
utilizes electrical control for the cells. The clamping of the cells can
be removed at any time. It is very advantageous for collection and
redistribution of cell products.
