为了满足测量单个细胞机械性能的高通量、无损技术的需求,我们开发了光学对准压缩 (OAC) 细胞计数仪。 OAC 将拉伸流动微流体装置中的流体动力阻力与廉价二极管激光器产生的光学力相结合,以诱导压缩细胞之间可测量的变形。在这种情况下,低强度线性光陷阱将进入的细胞与流动停滞点对齐,从而允许流体动力阻力在细胞与细胞相互作用期间引起变形。通过这种新颖的方法,我们测量了电池的机械性能,其吞吐量显着提高了当前的非破坏性单个电池测试方法。
To address the need for a high throughput, non-destructive technique for measuring individual cell mechanical properties, we have developed optical alignment compression (OAC) cytometry. OAC combines hydrodynamic drag in an extensional flow microfluidic device with optical forces created with an inexpensive diode laser to induce measurable deformations between compressed cells. In this, a low-intensity linear optical trap aligns incoming cells with the flow stagnation point allowing hydrodynamic drag to induce deformation during cell-cell interaction. With this novel approach, we measure cell mechanical properties with a throughput that improves significantly on current non-destructive individual cell testing methods.
