    Project Details


    The microchip-based micro conductance particle counter (µCPC) is a device employing the Coulter principle for counting and sizing of cells in liquid media. The µCPC has been fabricated as a planar silicon structure and sealed with a glass lid, which enables detailed observation during operation. The µCPC employs a variable aperture that allows for hydrodynamically adjusting the sensitivity for a specific type of particles. Furthermore, microtechnology gives us complete freedom over how to implement the counting orifice in a system of channels. Furthermore, making the device in silicon allows for integration of various functions such as sorting and optical detection. All in all, the µCPC could give rise to many new approaches in medical diagnostics e.g. low cost, portable equipment for decentralised health care.
