We developed a microfluidic resistive pulse-based cell sensor driven by a syringe pump and a small electric field to precisely count and size yeast and E. coli, as well as measure their density. The microfluidic sensor consisted of one small sensing aperture (10 µm×8 µm cross-section and 15 µm long)...
