Flow cell array and uses thereof
Apparatus and methods for using a flow cell array are provided herein. A method includes determining placement of one or more reaction sites on a first component; providing a material for the one or more reaction sites in one or more surface channels of the first component; connecting the first component to a second component to form an array, wherein the one or more surface channels of the first component connect the one or more reaction sites with one or more vias, and wherein the second component comprises the one or more vias connected to multiple sub-surface channels; and aligning the one or more surface channels of the first component with the one or more vias of the second component to form a connection between the first component and the second component.
1. A method comprising:
determining locations for multiple reaction sites in multiple surface channels of a first component, and wherein the multiple surface channels are aligned to the Y direction, wherein the multiple reactions sites are within a pixel of approximately one micrometer in size;
connecting the first component to a second component, wherein said connecting comprises forming a fluidic connection between each of the multiple surface channels of the first component and respective pairs of sub-surface channels of the second component via a respective pair of vias of the second component, and wherein the sub-surface channels of the second component are aligned to the X direction;
wherein each of the pairs of sub-surface channels is designated for use with (i) a distinct one of multiple chemical matters, (ii) one or more of the multiple reaction sites designated for use with the distinct one of the multiple chemical matters, and (iii) one or more of the multiple surface channels connected to the one or more reaction sites designated for use with the distinct one of the multiple chemical matters; and
delivering said multiple chemical matters to the multiple reaction sites in the multiple surface channels of the first component.
2. The method of claim 1 , wherein the multiple surface channels of the first component comprise one or more microfluidic surface channels.
3. The method of claim 1 , wherein the sub-surface channels of the second component comprise microfluidic sub-surface channels.
