We have developed a general approach to prepare fluorescent quantum dots within protein single crystals without disturbing the protein crystalline lattice. The quantum dots are three-dimensionally incorporated within the protein crystals, and their fluorescence properties are tunable.

Graphene induces and plays a decisive role in shaping the dendrite morphology of Pd nanostructures formed on its surface. The synergetic effect of the graphene support and the dendrite morphologyof Pd nanostructures triggers the high electrocatalytic activity and the catalyst shows robust tolerance to surface poisoning.

Ultra-narrow (1.5 nm diameter) and long gold nanowires forming nanoscale bundles are connected to gold electrodes. The electronic transport is dominated by charging effects mediated by the temperature and the bias voltage. At low temperature, the current flow is governed by cooperative electron motions between the weakly coupled Au-nanowires. We extract a 1D localization length of the electronic wave function along the nanowires of the order of 120 nm, which is remarkably large, considering the ultra-narrow diameter of the wires. This result confirms the high crystallinity of the nanowires, in consistency with high resolution transmission electron microscopy.

Raman spectra of topological insulator Bi2Te3 films prepared by molecular beam epitaxy (MBE) have been measured by an in situ ultrahigh vacuum (UHV)每MBE每Raman spectroscopy system. When the thickness of the Bi2Te3 films decreases from 40 quintuple-layers (QL) to 1 QL, the spectral characteristics of some Raman modes appearing in the spectrum of bulk Bi2Te3 vary, and a new vibrational mode appears.

A pH-responsive water-dispersible method for the exfoliation and functionalization of graphene by using lysozyme is presented. The pH-responsive dispersion of graphene may be useful for the construction of a reversible controlled release system. More importantly, a hybrid catalyst constructed through the interactions between disulphide groups in lysozyme and gold nanoparticles shows excellent catalytic activity towards the reduction of o-nitroaniline by NaBH4.
