    The rapid development of nanomaterials science and technology calls for a multifunctional data system, namely the Nanomaterials Genome. It is designed for intelligent and convenient categorizing, organizing, sifting, sorting and connecting pertinent nano-information about the known nanomaterials, and utilizing this information to explore the unknown in scientifically and technologically innovative ways, ultimately to create new advanced materials and biomedical based products and processes that benefit humanity.

  2. Silicon Nanohybrid-based Surface-enhanced Raman Scattering Sensors

    Houyu Wang, Xiangxu Jiang, Shuit-Tong Lee and Yao He

    Article first published online: 22 SEP 2014 | DOI: 10.1002/smll.201401563

    Silicon nanohybrid-based SERS substrates, featuring significant SERS enhancement factors and superior reproducibility, have been extensively explored and employed for the construction of novel silicon-based SERS sensors in recent years, enabling chemical and biological detection in a sensitive, specific, and reproducible manner. Representative achievements in this area are summarized in a detailed way in this review.

  3. Metal-Cluster-Decorated TiO2 Nanotube Arrays: A Composite Heterostructure toward Versatile Photocatalytic and Photoelectrochemical Applications

    Fang-Xinh Xiao, Sung-Fu Hung, Jianwei Miao, Hsin-Yi Wang, Hongbin Yang and Bin Liu

    Article first published online: 22 SEP 2014 | DOI: 10.1002/smll.201401919

    A well-defined heterostructure consisting of monodisperse Au clusters and hierarchically ordered nanoporous TiO2 nanotube arrays (Aux/NP-TNTAs) is fabricated via a facile two-step anodization approach combined with efficient electrostatic self-assembly. The hierarchically ordered Aux/NP-TNTA heterostructure demonstrates versatile photocatalytic redox and photoelectrochemical performances under simulated solar light irradiation under ambient conditions.

  4. Functional Nanomaterials Can Optimize the Efficacy of Vaccines

    Ye Liu, Yingying Xu, Yue Tian, Chunying Chen, Chen Wang and Xingyu Jiang

    Article first published online: 19 SEP 2014 | DOI: 10.1002/smll.201401707

    Nanomaterials, such as peptide-based materials, non-peptide polymers, carbon, gold, silver, and calcium salts can act as carriers and/or immunoregulators to optimize the efficacy of vaccines in multiple ways, including enhancing the uptake of antigen-presenting cells against antigens, stimulating the proliferation of immunologic effector cells, and regulating immunity profiles induced by vaccines.

  5. Electrostatically Assembled CdS–Co3O4 Nanostructures for Photo-assisted Water Oxidation and Photocatalytic Reduction of Dye Molecules

    Omer Yehezkeli, Débora R. B. de Oliveira and Jennifer N. Cha

    Article first published online: 19 SEP 2014 | DOI: 10.1002/smll.201401490

    Electrostatic assembly is used here to couple CdS nanorods with Co3O4 nanoparticles into photocatalytic systems that simultaneously oxidize water and mediate electron transfer. Layered films of CdS nanorods and Co3O4 nanoparticles are first used to generate high photo­currents electrochemically as opposed to CdS or Co3O4 alone. Dispersed clusters of CdS nanorods conjugated with Co3O4 nanoparticles are next shown to efficiently oxidize water and reduce methylene blue in solution.
