A 3D filter array contained micropillars inside a channel to accomplish cell separation within the plane as well as with the plane, while the MSCs with a larger size will not mix the filter but instead roll down. 3D construction achieves high throughput, high recovery rate, and device robustness with minimum clogging. We shown proof\of\basic … Continue reading A 3D filter array contained micropillars inside a channel to accomplish cell separation within the plane as well as with the plane, while the MSCs with a larger size will not mix the filter but instead roll down
