Abstract: A micro-fluidic method for continuous pressure-driven flow injection analysis and a planar microfluidic device intended for pressure driven flow injection analysis are provided. A network of microchannels allows a continuous flow of sample stream on the devices, as well as facile and reproducible analyte plug injection to a reagent or buffer stream on microchip-based devices. The method allows for sequent separation analysis without additional purging cycles.

Abstract: A non-volatile random access memory (NVRAM) of the type with magnetoresistive memory elements (1) connected by sets of non-intersecting conductor sense lines (3, 4) which define the address of each memory element (1) and are connectable to a magnetic write/read recording unit. The memory elements are a plurality of magnetoresistive submicron dots or wires (1) embedded in a membrane (2) through which the submicron dots or wires extend. The sets of non-intersecting conductor sense lines (3, 4) are connected to the opposite ends of the submicron dots or wires (1) on opposite sides of the membrane.
