Abstract Dielectrophoresis (DEP) particle separation has label‐free, well‐controllable, and low‐damage merits. Sidewall microelectrodes made of liquid metal alloy (LMA) inherits the additional advantage thick electrodes to generate impactful DEP force. However, existing LMA electrode‐based devices lack ability integrate large‐array in a compact footprint, severely limiting flow rate thus throughput. Herein, facile versatile method is proposed high‐density microfluidic devices, taking passive...
Single-cell impedance measurement is a label-free, noninvasive method for characterizing the electrical properties of single cells. At present, though widely used measurement, electric flow cytometry (IFC) and spectroscopy (EIS) are alone most microfluidic chips.

CFIMC adopts a framework couples the impedance electrodes with constriction channel spatially, so signals contain dynamic deformability...
Non-invasive and rapid imaging technique at subcellular resolution is significantly important for multiple biological applications such as cell fate study. Label-free refractive-index (RI)-based 3D tomographic constitutes an excellent candidate of cellular structures, but its full potential in long-term spatiotemporal observation locked due to the lack efficient integrated system. Here, a RI system incorporating cutting-edge white light diffraction phase microscopy module with stability,...
