Sorting and Trapping Human Cells Using a Matrix of Square Micro-Magnets

Sorting and Trapping Human Cells Using a Matrix of Square Micro-Magnets

In this work we present a study on sorting and trapping some living human cells, including red blood cells (RBCs) and breast cancer cells (denoted T47D), by using patterned micro-magnets with dimensions of each micro-magnet 50 × 50 µm2. The diamagnetic properties of these cells and the force exerted...

Description
Summary:In this work we present a study on sorting and trapping some living human cells, including red blood cells (RBCs) and breast cancer cells (denoted T47D), by using patterned micro-magnets with dimensions of each micro-magnet 50 × 50 µm2. The diamagnetic properties of these cells and the force exerted on them along the z-axis have been investigated. The diamagnetic levitation height of each cell has been both theoretically calculated and experimentally studied. The results open a novel possibility for positioning living cells with further applications to medical diagnostics.
