Microfluidic Devices with Integrated Controlled Magnetic Field Sources

This work considers several methods of manufacturing microfluidic chips based on a sandwich structure using Parafilm® film as well as PDMS microfluidics using a standard 3D printer, ABS plastic, and acetone. Various combinations of electric coils and permanent magnets are used as sources of an inhomogeneous magnetic field. Using each of the technologies, a series of microfluidic chips was manufactured; during their production, the technological parameters were varied: the temperature, pressure and sintering time, the composition of the polymer matrix and the washing technology. The optimal production technology was determined on the basis of microscopic analysis and technological tests.
