The present invention presents a device and methods of use thereof in combined electrohydrodynamic concentration and plasmonic detection of a charged species of interest using a flow-through nanohole array. Each of the microcontrollers is associated with one of the main functions. The invention also relates to methods for producing a soybean plant containing in its genetic material one or more transgenes and to the transgenic soybean plants and plant parts produced by those methods. The ingestible circuitry finds use in a variety of different applications, including as components of ingestible identifiers, such as may be found in ingestible event markers, e. Both of the side effectors are also resiliently supported to the substrate to be movable towards the actuator by being electrostatically attracted thereto and away from the actuator by resiliency. The flashlight body includes an interchangeable bottom wall, suitable for engraving, printing, silk screening, or stamping.
