Integrated affinity column–microchip CE devices for biomarker quantitation. (A) Layout of an integrated AFP analysis microdevice. (B) Photograph of a microfluidic device with integrated anti-AFP affinity column. Scale bar is 1 cm. (C) Microchip CE of Alexa Fluor 488 labeled human serum and of AFP standard solutions after affinity column extraction. (D) Microchip CE of Alexa Fluor 488 labeled human serum after standard addition and affinity column extraction. (E) Calibration curve generated from peak heights in (C), with the unknown sample data point indicated with a star. (F) Standard addition plot of concentration of standard added vs. peak height generated from peak heights in (D). Adapted and reproduced from Ref. 94, with permission from ACS.
