| Abstract | Flow cytometry is among the most powerful tools for single-cell analysis, while the high cost and mechanical complexity of the commercial instrumentation limit the applications in personalized single-cell analysis. For this issue, we hereby construct an open and low-cost flow cytometer. It is highly compact to integrate the functions of (1) single cell aligning by a lab-made modularized 3D hydrodynamic focusing device, and (2) fluorescence detection of the single cells by a confocal laser-induced fluorescence (LIF) detector. The ceiling cost of the entire hardware for the LIF detection unit and 3D focusing device is $ 3200 and $ 400 respectively. A sheath flow velocity of 150 mu L/min produces a focused sample stream of 17.6 mu m x 14.6 mu m at sample flow of 2 mu L/min, based on the LIF response frequency and the laser beam spot diameter. The assay performance of the flow cy-tometer was evaluated by characterizing fluorescent microparticles and acridine orange (AO) stained HepG2 cells, producing throughputs of 40.5/s and 6.2/s respectively. Favorable assay precision and accuracy were demonstrated by the agreement of frequency histogram with imaging analysis, and good Gaussian-like distri-butions of fluorescent microparticles and AO-stained HepG2 cells. Practically, the flow cytometer was success-fully applied for the evaluation of ROS generation in single HepG2 cells. |
