Optical and fluidics cross-talk between channels. A clear LOC with fluidics trap (A), a black LOC with fluidics trap (B) and a black LOC without fluidics trap (C) were loaded with fluorescein (channels 1, 3, 5 and 7) and water (channels 2, 4, 6 and 8). The LOCs were incubated for 120 minutes at room temperature and the signal from the detection wells marked with an arrow was measured every 15 minutes. The plot of diffusion cross talk for the water channels (D) was calculated as a signal/noise ratio where noise is signal at T0 (before diffusion started) without trap (a), with trap (b).
