- Hierarchical 3D SERS Substrates Fabricated by Integrating Photolithographic Microstructures and Self-Assembly of Silver Nanoparticles

Article first published online: 10 MAR 2014 | DOI: 10.1002/smll.201303773
Hierarchical 3D surface-enhanced Raman scattering (SERS) substrates fabricated by integrating the two-photon photolithography and Langmuir-Blodgett assembly of Ag nanocubes are reported and their SERS efficiency is systematically studied. This design extends the SERS hotspots into the third dimension along the z-axis. In particular, the tolerance of the z-direction SERS hotspots is increased from the nanometer to micrometer length scale. This phenomenon is applied to encrypt information in the form of micron-sized binary barcodes.

A fluorescent light-up nanoprobe based on gold nanoparticles (AuNPs) and polyelectrolyte is prepared through sequentially coating of Au NPs with a pH-responsive charge-reversible polymer and a cationic conjugated polyelectrolyte (CPE). This obtained nanoprobe shows a light-up response to the low pH extracellular (pHe) microenvironments in tumors, and can be used for in vitro and in vivo tumor imaging with high contrast.
- Lipid Bilayers on a Picoliter Microdroplet Array for Rapid Fluorescence Detection of Membrane Transport
Taishi Tonooka, Koji Sato, Toshihisa Osaki, Ryuji Kawano and Shoji Takeuchi
Article first published online: 10 MAR 2014 | DOI: 10.1002/smll.201303332
Picoliter-sized lipid bilayer chambers and a theoretical model for rapid fluorescence detection of membrane transport are presented. Detection time of the transport phenomena in the chamber decreases in inverse proportion to the ratio of lipid bilayer area to chamber volume, which is supported by the simulated results based on the model.
- Selective Formation of Carbon-Coated, Metastable Amorphous ZnSnO3 Nanocubes Containing Mesopores for Use as High-Capacity Lithium-Ion Battery
Fei Han, Wen-Cui Li, Cheng Lei, Bin He, Kyoichi Oshida and An-Hui Lu
Article first published online: 10 MAR 2014 | DOI: 10.1002/smll.201400371
Carbon-coated amorphous ZnSnO3 nanocubes with well-developed mesoporosity are synthesized and the core–shell particles are linked into an interconnected conductive framework. This ZnSnO3-based anode exhibits an outstanding lithium storage performance, especially a high reversible capacity of 1060 mA h g−1 because of the integration of alloying and conversion reaction processes (reversible transformation of Li4.4Sn and LiZn alloys to pristine ZnSnO3).
- Generation of Fully-Covering Hierarchical Micro-/nano- Structures by Nanoimprinting and Modified Laser Swelling

Article first published online: 10 MAR 2014 | DOI: 10.1002/smll.201303656
The paper presents a facile technique for the fabrication of fully-covering multiscale structures surfaces by nanoimprinting and modified laser swelling. The approach has been proved to be capable of generating regular and adjustable dome-like hierarchical structures, and it is used to create nature-inspired, multiscale functional surfaces with tunable wettability.
