Lab-on-a-Chip Devices for Chemical Analysis, Fig. 6 Geometric layout of channels etched with glass plate, (a) Reservoirs A, B, and C are connected to the electrophoresis injector and the separation capillaries, which form the U-shaped cell with a 100-140 pm longitudinal pathlength. Reservoirs D and E are connected to chatmels into which optical fibers are inserted to launch... 

Lab-on-a-Chip Devices for Chemical Analysis, Fig. 9 (a) Schematic of experimental setup and (b) microchip layout. The device comprises two inlets, a meandering mixing channel, a detection chamber, and an outlet. The inlets are 400 pm wide, 800 pm deep, and... 

Lab-on-a-Chip Devices for Chemical Analysis, Fig. 10 Schematic of a monolithically integrated optical longpass filter. The structured dye-doped PDMS layer is able to serve concurrently as the microchannel medium and optical filter, negating the need for an additional filter layer and allowing for improved collection of the fluorescence signal, since the detector can he placed in closer proximity to the channel. The enclosed microchannels are...
