Abstract

We present a method to stably rotate cells about a rotation axis perpendicular to the imaging axis, using a combination of hydrodynamic microvortex flow and optical trapping on a microfluidic chip. We present theoretical simulations, fabrication, system setup, rotation imaging, and data analysis. A tilted backside exposure technique was used to fabricate trapezoidal features which form the site for microvortical flow. Optical trapping was used to hold the cell in this flow, thereby stabilizing cell rotation. The integrated setup can be utilized for 3D single cell imaging with sub-micron isotropic spatial resolution.
