Micro-Hall detection of rare cells. a. A SEM micrograph of an array of eight 8×8μm2 Hall sensors. b. A fluorescence micrograph of a-hydrodynamic focusing structure, demonstrating that focusing can be controlled by utilizing a combination of vertical and lateral sheaths. c. Clinical applications of the μHall sensor. CTCs in patient blood samples with late stage ovarian cancer (n=20) were detected using the μHall sensor and with a clinical gold standard system, CellSearch (bottom). The μHall detected CTCs in all cancer patients, even those that were not detected using the gold standard [6].
