Squeezing Cells to Get the Drugs In

Jan-02-15 A new drug-delivery technology that squeezes cells to force the medication inside could offer new treatment options for cancer and HIV patients.

The microfluidic device works using a sample of white blood cells extracted from the patient. Those cells are inserted into a reservoir in the device along with the material to be introduced, and the mixture is then sent flowing though the device's 75 micro-channels. A carefully timed flow pushes the blood cells through a constriction halfway through, stretching them out and allowing the desired material to enter the cells. The white blood cells can then be injected back into patient.
