http://www.freepatentsonline.com/7570355.html

This patent from Hewlett Packard focuses on a variation of Raman spectroscopy using nanowire heterostructures to increase the sensitivity of molecular detection. Claim 1 reads:

1. A NERS-active structure comprising:

at least one heterostructure nanowire having at least two active regions and at least one inactive region between the at least two active regions, wherein the at least one heterostructure nanowire comprises at least one radial core-shell heterostructure nanowire.
