我们展示了一种在不同细胞类型的种群中打开活细胞的电子方法,其中细胞选择是基于它们的形状。我们在光电平台上实现了这项技术,其中从视频投影仪聚焦到半导体表面的光创建了可重新配置的电极图案。人们可以通过简单地重新绘制投影图案来实时选择要裂解的单元格区域,从单个单元格到大区域。我们表明,这种基于细胞投射的“电子阴影”的方法可以检测血液中罕见的细胞类型(包括昏睡病寄生虫),并有可能使单细胞研究用于高级分子诊断,以及在分析化学中得到更广泛的应用。
We show an electrical method to break open living cells amongst a population of different cell types, where cell selection is based upon their shape. We implement the technique on an optoelectronic platform, where light, focused onto a semiconductor surface from a video projector creates a reconfigurable pattern of electrodes. One can choose the area of cells to be lysed in real-time, from single cells to large areas, simply by redrawing the projected pattern. We show that the method, based on the “electrical shadow” that the cell casts, allows the detection of rare cell types in blood (including sleeping sickness parasites), and has the potential to enable single cell studies for advanced molecular diagnostics, as well as wider applications in analytical chemistry.
