1/ Tangential sorting
FEMTO ENGINEERING has developed a tangential sorting device, in a clean room, to separate white blood cells and red blood cells. This component is a technological brick integrated into a visualisation/electronics/interface system developed at the FEMTO-ST institute in the MN2S department.
The device can be fabricated on glass or silicon wafers. It consists of two overlapping channels and a perforated membrane, the holes measure a few microns in diameter. The length of the channels can reach a few tens of centimeters. It is possible to create several million holes in the microfluidic circuit.
2/ Acoustic sorting
A component for the purpose of acoustic sorting was manufactured in a clean room. In collaboration with the FEMTO-ST Institute, this technological brick separates lymphocytes platelets via their size and density. The silicon channel is then closed by a glass cover.
Electrodes are then etched by femtosecond laser to allow acoustic stimulation of the cells.
