Abstract: The present invention relates to a method of detecting a target microparticle in a fluid in a microfluidic particle analysis device comprising a measuring channel with a first electrode and a second electrode defining an operating space between and being in electrical connection with an electric current source and a device for monitoring an electrical signal from the first and/or the second electrode.

Abstract: The present invention relates to a microfluidic particle analysis device comprising an inlet and an outlet in fluid communication via a main channel defining a main flow direction from an inlet end to an outlet end, the main channel being defined by a main channel wall extending from the inlet end to the outlet end and having a first cross-sectional dimension in the range of 20 ?m to 120 ?m and a second cross-sectional dimension of at least 100 ?m, the main channel wall at a vertex having an opening extending along the main flow direction and being open to an analysis section having surfaces at an analytical distance in the range of 5 ?m to 50 ?m and a sensor system for detecting a particle. The present invention also relates to a method of using the microfluidic particle analysis device for detecting particles or monitoring the concentration of particles.
