Similarly, for cancer biomarker multiplexing detection, in 2012, Malhotra et al. presented an ultrasensitive detection of interleukin 6 (IL-6), IL-8, and vascular endothelial growth factor (VEGF) in the clinic with the use of a nanostructured microfluidic array in which the beads were magnetically separated into the array when they finished the capturing of the proteins and the washing step. The gene discussed is IL6; the disease is cancer.
