微流体技术已成为生物学家强大的实验室工具箱,通过利用与单细胞相关的尺寸尺度的微加工特征,允许在细胞和亚细胞水平上操纵和分析过程。在大多数微流体装置中,样品处理和分析发生在封闭的微通道内,对样品制备和使用施加了限制。我们提出了一种优化的非接触式开放体积微流体工具,以克服这些和其他限制,通过使用流体动力学限制的微流移液器,作为一个多功能的解决方案处理和分配工具。该工具的几何形状经过优化,可用于光学显微镜,集成了溶液储存器,可减少试剂使用、污染风险和清洁要求。使用落射荧光和全内反射荧光(TIRF)显微镜表征了器件性能,在距离表面约100 nm和约30 µm处的交换时间分别为约200 ms和约130 ms。
Microfluidics has emerged as a powerful laboratory toolbox for biologists, allowing manipulation and analysis of processes at a cellular and sub-cellular level, through utilization of microfabricated features at size-scales relevant to that of a single cell. In the majority of microfluidic devices, sample processing and analysis occur within closed microchannels, imposing restrictions on sample preparation and use. We present an optimized non-contact open-volume microfluidic tool to overcome these and other restrictions, through the use of a hydrodynamically confined microflow pipette, serving as a multifunctional solution handling and dispensing tool. The geometries of the tool have been optimised for use in optical microscopy, with integrated solution reservoirs to reduce reagent use, contamination risks and cleaning requirements. Device performance was characterised using both epifluorescence and total internal reflection fluorescence (TIRF) microscopy, resulting in ~200 ms and ~130 ms exchange times at ~100 nm and ~30 µm distances to the surface respectively.
