Imaging flow cytometry (IFC) combines conventional flow cytometry with optical microscopy, allowing for high-throughput, multi-parameter screening of single-cell specimens with morphological and spatial information. However, current 3D IFC systems are limited by instrumental complexity and incompatibility with available microfluidic devices or operations. Here, we report portable light-sheet optofluidic microscopy (PLSOM) for 3D fluorescence cytometric imaging. PLSOM exploits a compact, open-top light-sheet configuration compatible with commonly adopted microfluidic chips. The system offers a subcellular resolution (2-4 μm) in all three dimensions, high throughput (∼1000 cells per s), and portability (30 cm () × 10 cm () × 26 cm ()). We demonstrated PLSOM for 3D IFC using various phantom and cell systems. The low-cost and custom-built architecture of PLSOM permits easy adaptability and dissemination for broad 3D flow cytometric investigations.
成像流式细胞术（IFC）将传统流式细胞术与光学显微镜相结合，可对具有形态和空间信息的单细胞标本进行高通量、多参数筛选。然而，当前的 3D IFC 系统受到仪器复杂性和与现有微流控设备或操作不兼容的限制。在这里，我们报告了用于 3D 荧光细胞计量成像的便携式光片光流体显微镜（PLSOM）。PLSOM 利用与常用微流控芯片兼容的紧凑型、开放式光片配置。该系统在所有三个维度上均提供亚细胞分辨率（2-4 μm）、高通量（∼1000 个细胞/秒）和便携性（30 cm()×10 cm()×26 cm()）。我们使用各种幻影和细胞系统展示了 PLSOM 用于 3D IFC。PLSOM 的低成本和定制构建架构允许轻松适应和传播，以进行广泛的 3D 流式细胞术研究。
