B1: A schematic illustration of the integrated microfluidic chip for detecting miRNA biomarkers for cardiovascular disease. B2: Exposed view of the integrated microfluidic chip. B3: A photograph of the integrated microfluidic chip. The chip was comprised of four layers: an air control layer, a liquid channel layer, a double-sided tape layer, and an epoxy substrate equipped with an FET detection sensor. FET stands for field-effect transistor. Reprinted with permission from Ref. 217. Copyright 2018, The Royal Society of Chemistry.
