    Abstract: The invention provides a passive fluidics circuit for directing different fluids to a common volume, such as a reaction chamber or flow cell, without intermixing or cross contamination. The direction and rate of flow through junctions, nodes and passages of the fluidics circuit are controlled by the states of upstream valves (e.g. opened or closed), differential fluid pressures at circuit inlets or upstream reservoirs, flow path resistances, and the like. Free diffusion or leakage of fluids from unselected inlets into the common outlet or other inlets at junctions or nodes is prevented by the flow of the selected inlet fluid, a portion of which sweeps by the inlets of unselected fluids and exits the fluidics circuit by waste ports, thereby creating a barrier against undesired intermixing with the outlet flow through leakage or diffusion. The invention is particularly advantageous in apparatus for performing sensitive multistep reactions, such as pH-based DNA sequencing reactions.

    Abstract translation: 本发明提供了一种用于将不同流体引导到公共体积（例如反应室或流动池）的无源流体回路，而不会混合或交叉污染。 通过流体回路的连接点，节点和通道的流动方向和流速由上游阀（例如打开或关闭）的状态，电路入口或上游储存器处的差分流体压力，流动阻力等来控制。 通过所选择的入口流体的流动防止流体从未选择的入口到共同的出口或其他入口处的自由扩散或泄漏，其一部分由未选择的流体的入口扫过并且通过废气端口离开流体回路 ，从而产生阻止与出口流通过泄漏或扩散的不期望的混合的屏障。 本发明在用于进行灵敏多步反应（例如基于pH的DNA测序反应）的装置中特别有利。

    Abstract: An apparatus includes a fluidic coupler including an opening. A first port is in fluid communication with the opening and is to interface with an inlet of a flow cell of a sensor device. A second port is to interface with an outlet of the flow cell of the sensor device. A third port is in fluidic communication with the second port. The apparatus further includes a mechanical assembly moveable between a first position and a second position. The fluidic coupler is secured to the flow cell of the sensor device in the first position. The fluidic coupler is disengaged from the flow cell of the sensor device in the second position.

    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.
