Here we describe enhanced Raman scattering at Au electrode 1 (E1)/Ag nanowire (NW)/4-aminothiophenol (4-ATP)/Au electrode 2 (E2) nanojunctions fabricated by combining self-assembly and metal electrodeposition at microgap electrodes (E1 and E2). In this method we assemble the 4-ATP on electrode E2 and electrodeposit Ag on the opposite electrode E1 of an Au interdigitated array (IDA) electrode device. The electrodeposited Ag grows in the form of NWs on E1 and makes nanoscale contact to E2 to form the junctions. The presence of the Ag NW leads to strong Raman scattering of the 4-ATP molecules within the nanojunction leading to estimated enhancement factors ranging from 10(3) to 10(6). Scanning electron microscopy (SEM) images provide insight into the morphology of the junctions. The magnitude of the Raman enhancement depends on the extent of contact between the Ag NW and the 4-ATP self-assembled monolayer (SAM). With this approach we could detect 4-ATP molecules diluted by a factor of 1000 with hexanethiol molecules within the junctions. Our approach is simple and fast with the potential to correlate electronic measurements of molecules with Raman spectroscopy data of the same molecules in a nanoscale junction for molecular electronics or chemiresistive sensing applications.
