    Abstract: The invention is directed to apparatus and chips comprising a large scale chemical field effect transistor arrays that include an array of sample-retaining regions capable of retaining a chemical or biological sample from a sample fluid for analysis. In one aspect such transistor arrays have a pitch of 10 μm or less and each sample-retaining region is positioned on at least one chemical field effect transistor which is configured to generate at least one output signal related to a characteristic of a chemical or biological sample in such sample-retaining region. In one embodiment, the characteristic of said chemical or biological sample is a concentration of a charged species and wherein each of said chemical field effect transistors is an ion-sensitive field effect transistor having a floating gate with a dielectric layer on a surface thereof, the dielectric layer contacting said sample fluid and being capable of accumulating charge in proportion to a concentration of the charged species in said sample fluid. In one embodiment such charged species is a hydrogen ion such that the sensors measure changes in pH of the sample fluid in or adjacent to the sample-retaining region thereof. Apparatus and chips of the invention may be adapted for large scale pH-based DNA sequencing and other bioscience and biomedical applications.

    Abstract: A buffered suspension includes a surfactant and a solid buffer particulate having a point of zero charge at least 1.2 pH units different that the pH of the buffered suspension. The buffered suspension can be prepared by mixing a stock solution with the solid buffer particulate and titrating. A method of preforming a pH sensitive process includes drawing the buffered suspension from a reservoir, filtering the solid buffer particulate from the buffered suspension, and applying the filtered solution to a sensor.

    Abstract: A valve for regulating fluid flow includes a housing base defining a lower cavity and comprising a pinch structure within the lower cavity, a gas inlet providing external access to the lower cavity, a base fluid inlet, and a base fluid outlet. A housing cover defines an upper cavity and comprises a cover fluid inlet and a cover fluid outlet. The cover fluid inlet is in fluidic communication with the base fluid outlet between the upper cavity and the lower cavity, and the cover fluid outlet provides external access from the upper cavity. A diaphragm is disposed between the housing base and the housing cover. A pinch plate is disposed in the lower cavity and comprises a pinch point disposed opposite the pinch structure. A pinch tube is in fluidic communication between the base fluid inlet and the base fluid outlet in the lower cavity.
