Signal acquisition in the optofluidic chip. (A) Short record of the fluorescence signals obtained for the 1:10 sample. (B) Cross-correlogram of the green and red fluorescence signals. (C) Delay (Δt = −0.0119 s) between the read and the green signals. Results obtained with the (D) optofluidic chip and (E) flow cytometer for a sample containing 1 AU-565 (HER2+/EpCAM+) per 1000 RAMOS cells (HER2−/EpCAM−). (F) Comparison between the optofluidic chip and the flow cytometry cell ratios of 1:1, 1:10, 1:100 and 1:1000 Au-565:RAMOS.
