Micromolded Carbon Paste Microelectrodes for Electrogenerated Chemiluminescent Detection on Microfluidic Devices

The Cover Feature illustrates the electrogenerated chemiluminescent (ECL) reactions of tris(2,2’‐bipyridyl)ruthenium(II) and luminol at carbon paste microelectrodes on a microfluidic device. Samples with a volume of 500 nL are injected, giving the temporal profile shown below the devices. Photographs of the orange light from Ru(bpy)32+ and the blue light from luminol are shown on the device photographs. More information can be found in the Article by E. M. Gross et al.
