    The magnetic properties of silica coated magnetite nanoparticles are used to recover at different times the internalized nanoparticles from cells. This allows to characterize in a time resolved way the organelles in which nanoparticles are trafficked and the intracellular evolution of the layer of molecules adsorbed on the nanoparticle surface.

    Virus-Templated Plasmonic Nanoclusters with Icosahedral Symmetry via Directed Self-Assembly

    Plasmonic nanoclusters are fabricated by a self-assembly technique. Gold nanoparticles bind to an icosahedral genetically engineered plant virus. Purified samples result in a purple aqueous solution, which spectral characteristics agrees well with 3D finite-element simulations. Transmission electron micrographs confirms the assembly of nanoclusters with well-defined interparticle spacing and icoshahedral symmetry. This mehod has the potential for high-throughput providing a strategy to realize macroscopic quantities for metamaterial applications.

  3. Tunable Organic Hetero-Patterns via Molecule Diffusion Control

    Article first published online: 14 APR 2014 | DOI: 10.1002/smll.201303400

    A simple, scalable method is reported to fabricate ordered hetero-structures of organic materials using template-directed growth. The 3D extension of the structures is firstly determined by pre-pattern size and deposition amount, and can further be in situ tuned by annealing at appropriate temperature.

  4. Plasmonic Nanostars: In Vivo Volumetric Photoacoustic Molecular Angiography and Therapeutic Monitoring with Targeted Plasmonic Nanostars (Small 8/2014) (page 1441)

    Induced angiogenesis is a major hallmark of malignant tumor. As reported on page 1585, G. Lu, X. Chen, and co-workers design cyclic Arg-Gly-Asp (RGD) peptide conjugated plasmonic gold nanostars (RGD-GNS) to specifically target integrin avß3 overxpressed on tumor neovasculature. Quantitative volumetric angiography of tumors can be achieved with high resolution and deep penetration by a hemispherical photoacoustic imaging system. It also permits photothermal therapy and sequential therapeutic monitoring.
