Here, an alternative route is explored in... Robustness of Quantum Dot Power-Law Blinking [作者：Bharadwaj, P; Novotny, L,期刊：Nano Letters, 页码：2137-2141 , 文章类型： Article，,卷期：2011年11-5] Photon emission from quantum dots (QDs) and other quantum emitters is characterized by abrupt jumps between an "on" and an "off" state. In contrast to ions and atoms however, the durations of bright and dark periods in c... Reconfigurable Photonic Metamaterials [作者：Ou, JY; Plum, E; Jiang, L; Zheludev, NI,期刊：Nano Letters, 页码：2142-2144 , 文章类型： Article，,卷期：2011年11-5] We introduce mechanically reconfigurable photonic metamaterials (RPMs) as a flexible platform for realizing metamaterial devices with reversible and large-range tunable characteristics in the optical part of the spectrum... Perspective on the Prospects of a Carrier Multiplication Nanocrystal Solar Cell [作者：Nair, G; Chang, LY; Geyer, SM; Bawendi, MG,期刊：Nano Letters, 页码：2145-2151 , 文章类型： Article，,卷期：2011年11-5] This article presents a perspective on the experimental and theoretical work to date on the efficiency of carrier multiplication (CM) in colloidal semiconductor nanocrystals (NCs). Early reports on CM in NCs suggested la... Cells as Factories for Humanized Encapsulation [作者：Mao, ZW; Cartier, R; Hohl, A; Farinacci, M; Dorhoi, A; Nguyen, TL; Mulvaney, P; Ralston, J; Kaufmann, SHE; Mohwald, H; Wang, DY,期刊：Nano Letters, 页码：2152-2156 , 文章类型： Article，,卷期：2011年11-5] Biocompatibility is of paramount importance for drug delivery, tumor labeling, and in vivo application of nanoscale bioprobes. Until now, biocompatible surface processing has typically relied on PEGylation and other surf... Direct Imprinting of Porous Substrates: A Rapid and Low-Cost Approach for Patterning Porous Nanomaterials [作者：Ryckman, JD; Liscidini, M; Sipe, JE; Weiss, SM,期刊：Nano Letters, 页码：1857-1862 , 文章类型： Article，,卷期：2011年11-5] This work describes a technique for one-step, direct patterning of porous nanomaterials, including insulators, semiconductors, and metals without the need for intermediate polymer processing or dry etching steps. Our pro... Comparative Analysis of Viscosity of Complex Liquids and Cytoplasm of Mammalian Cells at the Nanoscale [作者：Kalwarczyk, T; Ziebacz, N; Bielejewska, A; Zaboklicka, E; Koynov, K; Szymanski, J; Wilk, A; Patkowski, A; Gapinski, J; Butt, HJ; Holyst, R,期刊：Nano Letters, 页码：2157-2163 , 文章类型： Article，,卷期：2011年11-5] We present a scaling formula for size-dependent viscosity coefficients for proteins, polymers, and fluorescent dyes diffusing in complex liquids. The formula was used to analyze the mobilities of probes of different size... Octopods versus Concave Nanocrystals: Control of Morphology by Manipulating the Kinetics of Seeded Growth via Co-Reduction [作者：DeSantis, CJ; Peverly, AA; Peters, DG; Skrabalak, SE,期刊：Nano Letters, 页码：2164-2168 , 文章类型： Article，,卷期：2011年11-5] Au/Pd octopods and concave core@shell Au@Pd nanocrystals have been prepared by coupling for the first time a seed-mediated synthetic method with co-reduction. The integration of these two methods is central to the format... pH Responsive Polymer Cushions for Probing Membrane Environment Interactions [作者：El-Khouri, RJ; Bricarello, DA; Watkins, EB; Kim, CY; Miller, CE; Patten, TE; Parikh, AN; Kuhl, TL,期刊：Nano Letters, 页码：2169-2172 , 文章类型： Article，,卷期：2011年11-5] A robust and straightforward method for the preparation of lipid membranes upon dynamically responsive polymer cushions is reported. Structural characterization demonstrates that complete, well-packed membranes with tuna... Graphene-Silicon Schottky Diodes [作者：Chen, CC; Aykol, M; Chang, CC; Levi, AFJ; Cronin, SB,期刊：Nano Letters, 页码：1863-1867 , 文章类型： Article，,卷期：2011年11-5] We have fabricated graphene-silicon Schottky diodes by depositing mechanically exfoliated graphene on top of silicon substrates. The resulting current voltage characteristics exhibit rectifying diode behavior with a barr... Tip-Enhanced Raman Scattering (TERS) from Hemozoin Crystals within a Sectioned Erythrocyte [作者：Wood, BR; Bailo, E; Khiavi, MA; Tilley, L; Deed, S; Deckert-Gaudig, T; McNaughton, D; Deckert, V,期刊：Nano Letters, 页码：1868-1873 , 文章类型： Article，,卷期：2011年11-5] Tip-enhanced Raman scattering (TEAS) is a powerful technique to obtain molecular information on a nanometer scale, however, the technique has been limited to cell surfaces, viruses, and isolated molecules. Here we show t... In Situ Transmission Electron Microscopy Observation of Microstructure and Phase Evolution in a SnO2 Nanowire during Lithium Intercalation [作者：Wang, CM; Xu, W; Liu, J; Zhang, JG; Saraf, LV; Arey, BW; Choi, DW; Yang, ZG; Xiao, J; Thevuthasan, S; Baer, DR,期刊：Nano Letters, 页码：1874-1880 , 文章类型： Article，,卷期：2011年11-5] Recently we have reported structural transformation features of SnO2 upon initial charging using a configuration that leads to the sequential lithiation of SnO2 nanowire from one end to the other (Huang et al.
