Medical Applications of Magnetorheological Fluids a Possible New Cancer Therapy

Abstract

This work demonstrates the principle of a novel cancer therapeutic method using magnetic fluids to block the blood supply to a tumor in order to starve it. Plastic tubes are used to simulate the simplest blood network. The sealing effect to the fluid flow is easily achieved at low particle concentrations with strong pressure resistance and reasonable sealing times at low flow rate (Q = 0.078 ml/min). At high flow rate (Q > 0.62 ml/min), oscillations in pressure and step increases in weight of the fluid are found.
