Electrophoresis 2017, 38 , 361–367. DOI: 10.1002/elps.201600319 This graphical representation demonstrates our ability to separate and detect analytes with the use of our photolithographic deterministic pillar arrays in combination with surface enhanced Raman spectroscopy. The two spectra shown represent unique vibrational data for adenine (left) and thymine (right) and their structures. The chromatogram peaks shown indicate the ability to separate and detect separate bands with good efficiency. Enhancement of the Raman signal was provided by the silver colloid present throughout the bottom of the pillar array. Included is a scanning electron microscope image of the pillar arrays, in which the silver colloid can be observed.
