Abstract:
1. An analytical device comprising a chip comprising: an array of zero mode waveguides in a transparent material, each zero mode waveguide having a sample within it, and each zero mode waveguide connected to a fluid conduit for bringing fluid to the zero mode waveguide, the fluid conduit surrounded by an opaque material preventing illumination light from entering the fluid conduit and preventing illumination light from entering a zero mode waveguide from above; wherein the chip is configured such that the illumination light enters the chip from above and is directed up into the bottom of the zero mode waveguides by reflective optical elements below the zero mode waveguides; wherein the illumination light stimulates emission from the sample within the zero mode waveguide into the transparent material to a detector below the zero mode waveguide.
