Microfluidic devices in bioanalysis offer advantages in terms of high-throuphput and reduced costs per analysis. In this paper James Rusling and colleagues at the University of Connecticut use gold compact disks in the construction of inexpensive immunomicroarrays. They then used their devices for the electrochemical detection of the cancer biomarker, interleukin-6 in diluted serum.
