Abstract

Apparatus and methods for using a flow cell array are provided herein. An apparatus includes an array comprising one or more pixels, wherein each of the one or more pixels comprises multiple reaction sites openings; a first set of one or more sub-surface channels, wherein each of the multiple reaction site openings is connected to a sub-surface channel from the first set of one or more sub-surface channels; a second set of two or more sub-surface channels; and multiple vias connecting each channel from the first set of one or more sub-surface channels to (i) a first sub-surface channel from the second set of two or more sub-surface channels and (ii) a second sub-surface channel from the second set of two or more sub-surface channels.

Claims

1. An apparatus comprising:

an array comprising one or more pixels, wherein each of the one or more pixels comprises multiple reaction sites openings;

a first set of one or more sub-surface channels, wherein each of the multiple reaction site openings is connected to a sub-surface channel from the first set of one or more sub-surface channels;

a second set of two or more sub-surface channels; and

multiple vias connecting each channel from the first set of one or more sub-surface channels to (i) a first sub-surface channel from the second set of two or more sub-surface channels and (ii) a second sub-surface channel from the second set of two or more sub-surface channels.

2. The apparatus of claim 1, further comprising:

a cover secured to the apparatus.

3. The apparatus of claim 2, wherein said cover is temporarily secured to the apparatus.

4. The apparatus of claim 2, wherein said cover is permanently secured to the apparatus.

5. The apparatus of claim 1, wherein each of the one or more pixels is configured to independently receive chemical matter at each of the multiple reaction site openings.

6. The apparatus of claim 1, wherein a size of each of the one or more pixels is based on an optical resolution of an imaging device associated with the apparatus.

7. The apparatus of claim 1, wherein each of the multiple reaction sites openings comprises an array of multiple openings.

8. The apparatus of claim 1, wherein location of each of the multiple reaction sites openings on each of the one or more pixels is based on utilization of one or more Gauss numbers.
