Raman spectroscopy with graphenated anodized aluminum oxide substrates.

We measured the Raman scattering of graphene deposited nanohole arrays. As the sample was azimuthally rotated, periodicities of 7.5 degrees and 5 degrees were revealed for the 2700 cm(-1) and 1600 cm(-1) Raman lines of graphene, respectively.

Polarization-dependent fluorescence of proteins bound to nanopore-confined lipid bilayers.

Lipid bilayers are essential structural component of biological membranes of all the living species: from viruses and bacteria to plants and humans. Biophysical and biochemical properties of such membranes are important for understanding physical mechanisms responsible for drug targeting. Binding events between proteins and the membrane may be ascertained by introducing fluorescence markers (chromophores) to the proteins.
