38. A flow cell comprising
(a) a transparent top window; -
(b) a transparent bottom window; (c) at least one channel between the transparent top window and the transparent bottom window; and (d) a spacer material between the transparent top window and the transparent bottom window, wherein a surface of the spacer material that faces the top window or the bottom window comprises a solid polymer material, wherein the solid polymer material comprises a spatial pattern of luminescent features that form a code carrying information indicating at least one manipulation carried out on the flow cell. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)
