    Ultrasound-controlled subcellular drug delivery is achieved with ultrasound-degradable mesoporous nanosilicon as a drug payload platform. This drug delivery strategy significantly amplifies therapeutic efficacy in vitro and in vivo by altering drug distribution within cells and increasing drug accumulation within the nucleus where their targets of action reside.

  2. Flexible Nonvolatile Transistor Memory with Solution-Processed Transition Metal Dichalcogenides

    Transition metal dichalcogenide (TMD)/polymer composite films are employed to a flexible top-gate floating-gate organic field-effect transistor nonvolatile memory as all-in-one floating/tunneling layers. Charge-trapping and detrapping properties of the composite films as a function of TMD nanosheets are systematically examined. Flexible memory properties are rarely altered after bending events over 500 times at a bending radius of 4.0 mm.

  3. Insights into the Influence of Work Functions of Cathodes on Efficiencies of Perovskite Solar Cells

    A systematic investigation on the impact of the work function of the cathode on the performance of inverted structure perovskite solar cells is provided. Lowering the work function of the cathode largely improves performance, including promoting the separation and conduction of charge carriers and even increasing the generation rate of excitons.

  4. A Smart Responsive Dual Aptamers-Targeted Bubble-Generating Nanosystem for Cancer Triplex Therapy and Ultrasound Imaging

    Feifei Zhao, Jie Zhou, Xiangjie Su, Yuhui Wang, Xiaosa Yan, Shaona Jia and Bin Du

    Version of Record online: 30 MAR 2017 | DOI: 10.1002/smll.201603990

    A multifunctional nanosystem as a theranostic agent in chemotherapy, photothermal therapy, biotherapy, and ultrasound imaging is achieved. The aptamers S2.2 and AS1411 are used in dual targeting to accurately deliver aptamers-targeted docetaxel (DTX) to tumor cells. The generated CO2 bubbles under 808 nm laser irradiation show strong ultrasonic signals for ultrasound imaging and facilitate DTX release.

  5. Rotating-Electric-Field-Induced Carbon-Nanotube-Based Nanomotor in Water: A Molecular Dynamics Study

    Md. Mushfiqur Rahman, Mokter Mahmud Chowdhury and Md. Kawsar Alam

    Version of Record online: 29 MAR 2017 | DOI: 10.1002/smll.201603978

    Carbon nanotubes suspended in water can be rotated with the aid of electric-field-induced water dipole orientations. Based on this phenomenon, a novel nanomotor configuration has been developed. The proposed nanomotor is capable of rotating gear-based complex structures as well as molecular scale loads with a precise angle.
