摘要： Methods, apparatuses, and systems associated with a sample testing device are provided. A method for fabricating a waveguide device includes forming a stress reducing pattern on a thermal silicon dioxide layer, wherein the stress reducing pattern comprises a plurality of polygon pattern units; and forming a silicon nitride film on the stress reducing pattern. A parallel flow multichannel pathogen sensing system includes a multichannel peristaltic pump comprising a plurality of pump flow channel tubes, wherein a buffer solution flows through the plurality of pump flow channel tubes, an injection valve array comprising a plurality of injection valves, and a sensing channel connection port connected to a sensing channel input port on a waveguide fluidics assembly. The waveguide fluidics assembly comprises a parallel flow micro-fluidic cover defining a plurality of sensing channel input ports.
