Micromachined inertial focusing triangular
WebDec 18, 2024 · Here, we present a new approach to single-stream inertial focusing based on a triangular microchannel geometry. Changing the channel cross-sectional shape leads to asymmetry in the velocity profile, resulting in a size-dependent single stable equilibrium position near the channel apex. We demonstrate that soft lithography masters for such ... WebDec 20, 2024 · In this study, particle focusing phenomena are studied in parallelogram and rectangular cross-sectioned microchannels of varying aspect ratio. In contrast to prior work the microchannels were fabricated using anisotropic wet etching of a Si wafer, plasma bonding, and self-alignment between the Si channel and the PDMS mold. It is shown that …

WebJun 7, 2024 · Inertial focusing offers passive manipulation techniques of cells or microparticles with extremely high throughput. We devised a 3D-curved triangular channel using a flexible, thin PDMS microfluidic device to control inertial focusing positions. The flexible PDMS channel is coiled to form 3D spiral channels, which can provide a … WebStudies on cell separation with inertial microfluidics are often carried out with solid particles initially. When this condition is applied for actual cell separations, the efficiency typically becomes lower because of the polydispersity and deformability of cells. Therefore, the understanding of deformability-induced lift force is essential to achieve highly efficient …
