Abstract: Embodiments of the invention include methods for detecting and determining the concentrations of macro and small molecules, including bio-molecules, in a liquid or gaseous sample.

Abstract: Embodiments of the invention relate generally to devices and methods for pumping and controling the flow of a fluid. More particularly, embodiments of the invention relate to capacitive pumping and flow control devices and methods. In one embodiment, the invention provides a pump system having an inlet valve, an outlet valve, and a chamber between and in communication with each of the inlet valve and the outlet valve, the chamber having at least one elastic surface, wherein the chamber will dilate in response to a fluid exerting a pressure on the elastic surface, contain a quantity of the fluid when so dilated, and discharge the quantity of the fluid through the opened outlet valve.

Abstract: The present invention relates to a nano-particle biochip substrate comprising a substrate having attached thereto (bearing), on or in a surface, nano-particles having a cross sectional diameter of from about 0.1 nm. to about 50 nm. and useful to immobilize one or more moieties of interest.
