Multilayer microdevice, and process for preparing said multilayer microdevice

NOVELTY – The micro-device has a surface containing micro channels and a surface having integrated electrodes and containers (1-4). The material making up the micro channels is chosen from toner with magnetized nanoparticulate materials, thermoplastic nanoparticulate materials, polymer and ferromagnetic composites. USE – Multilayer micro-device for electrophoretic separation of inorganic cation mixture, for use in chemical, clinical, biological, forensic, environmental, food, pharmacological analyses, etc. Can also be used in polyester-toner microchips used as portable and disposable analysis microchips for monitoring clinical diagnostics, chemical, national defense, beverage analysis, etc. ADVANTAGE – The mass production of micro-device is improved. The unit cost and manufacturing time of the device are reduced. DETAILED DESCRIPTION – An INDEPENDENT CLAIM is included for method for manufacturing multilayer micro-device. DESCRIPTION OF DRAWING(S) – The drawing shows a schematic view of the micro-device produced with polyester toner. Sample container (1) Buffer container (2) Sample disposal container (3) Buffer disposal container (4) Signal generator (5)
