Micropost Matrix

Micropost matrix for trapping and manipulating single cells.
(a) Micrograph of the micropost matrix.
(b) A schematic 3-D view of the device.

We have developed a micropost matrix that can move small particles and biological cells, through a microfluidic system using dielectrophoresis. Rf voltages are separately applied to each post, under computer control. The micropost matrix can independently trap and move a number of particles or cells through the fluid.
