Abstract

DNA nucleobases were detected by the Surface-enhanced Raman spectroscopy (SERS) performed on nanostructured InGaN quantum wells decorated with Al nanoparticles. The size of nanoparticles were varied by changing the Al layer thickness before annealing. The SERS intensity of 19-mer thymine was found be effectively enhanced as the Al layer thickness exceeds 40 nm.
