Abstract: This invention concerns an electronic device for the control and readout of the electron or hole spin of a single dopant in silicon. The device comprises a silicon substrate in which there are one or more ohmic contact regions. An insulating region on top of the substrate. First and second barrier gates spaced apart to isolate a small region of charges to form an island of a Single Electron Transistor (SET). A third gate over-lying both the first and second barrier gates, but insulated from them, the third gate being able to generate a gate-induced charge layer (GICL) in the beneath it. A fourth gate in close proximity to a single dopant atom, the dopant atom being encapsulated in the substrate outside the region of the GICL but close enough to allow spin-dependent charge tunnelling between the dopant atom and the SET island under the control of gate potentials, mainly the fourth gate.

A third gate over-lying both the first and second barrier gates, but insulated from them, the third gate being able to generate a gate-induced charge layer (GICL) in the ESR line substrate beneath it. A fourth gate in close proximity to a single dopant donor gate atom, the dopant atom being encapsulated in the substrate outside the region of the GICL but close enough to allow spin-dependent charge tunnelling between the dopant atom and the SET island under the control of gate potentials, mainly the fourth gate.

Abstract: A neutralizing agent is directed from a first reservoir formed in a substrate of a micro-fluidic device through a second reservoir formed in the substrate after contents of the second reservoir are dispensed.

Abstract: A dispenser for building a lateral flow immunoassay device comprises a fluid supply assembly and a jetting assembly. The fluid supply assembly comprises an antibody component including a plurality of reservoirs to supply at least one of member of a group comprising a species array of at least one species-specific antibody material, an anti-species array of at least one first anti-species antibody material, and a label-antibody array of at least one of a tag material and a second anti-species antibody material. The jetting assembly is in communication with the fluid supply assembly to enable dispensing the materials of the species array, the anti-species array, and the label-antibody array from the supply assembly onto a substrate.

Abstract: A lateral flow device, and related systems and methods is disclosed. A method of building a lateral flow immunoassay device comprises dispensing, via a fluid ejection device, a flow-inducing substance to form a flow membrane, and dispensing, via the fluid ejection device, a measured volume of biosubstances from an array of biosubstances to form a sample module, a tagging module, a reaction module, and a waste module on the membrane.

Abstract: A method of forming a biological sensor on a predetermined area of a substrate. The method includes dispensing a plurality of layers on the predetermined area of the substrate. Each of the plurality of layers is formed of a substantially different fluid having a substantially different function. The dispensing of the layers is accomplished by a drop generating member.
