Optimization and Parametric Characterization of a Hydrodynamic Microvortex Chip for Single Cell Rotation


Abstract Volumetric cell imaging using 3D optical Computed Tomography (cell CT) is advantageous for identification and characterization of cancer cells. Many diseases arise from genomic changes, some of which are manifest at the cellular level in cytostructural and protein expression (functional) features which can be resolved, captured and quantified in 3D far more sensitively and specifically than in traditional 2D microscopy. Live single cells were rotated about an axis perpendicular to the optical axis to facilitate data acquisition for functional live cell CT imaging. The goal of this thesis research was to optimize and characterize the microvortex rotation chip. Initial efforts concentrated on optimizing the microfabrication process in terms o... (more)
