Rapid identification of microparticles in liquid is an important problem environmental and biomedical applications such as microplastic detection water sources physiological fluids. Existing spectroscopic techniques are usually slow not compatible with flow-through systems. Here we analyze single the 10–24 μm range using a combination two electronic sensors same microfluidic system: microwave capacitive sensor resistive pulse sensor. Together, this integrated system yields electrical signature analyte particles for their differentiation. To simplify data analysis, 3D electrode arrangements were used instead planar electrodes so that generated signal unaffected by height particle channel. With platform, able to distinguish between polystyrene (PS) polyethylene (PE) microparticles. We showcase sensitivity speed technique discuss implications future application cytometry technology fields.
