Microfluidics apparatus and methods

摘要: This invention relates to microfluidics apparatus and methods for particle concentration in sensors sensing biological entities such as cells, spores the like. We describe a microfluidic sensor particles including device performing of three dimensions. The comprises substrate bearing channel or chamber carrying conductive fluid particles. has: first second electrodes spaced apart on defining an electric field therebetween, surface inner chamber. means applying ac voltage across perform simultaneously: i) electrohydrodynamic generation convection current flow fluid; ii) 3D said by dielectrophoretic attraction repulsion towards away from region increased field, increase at sensor.
