    A unique aggregation-induced-emission glyconanoparticle (AIE-GNP) is produced by the self-assembly between a silole-based AIEgen and glycoprobes for the ratiometric detection of β-amyloid peptides and fibrils. The AIE-GNP shows a different ratiometric response to lectins that recognize the glycoprobes, thus enabling a discrimination between two biomolecular analytes that both interact with the material.

  2. Deterministic Integration of Out-of-Plane Sensor Arrays for Flexible Electronic Applications

    A design strategy for fully flexible electrode arrays with out-of-plane through polymer vias (TPVs) for monolithic 3D integration of sensor readout circuitry is presented. The TPVs are formed using copper embedded in thin polyimide structure for support. The copper interconnects offer a stable impedance frequency response from DC to 100 kHz (Z ≈ 20 Ω, θ ≈ 0°).

  3. Chitosan Nanofibers for Specific Capture and Nondestructive Release of CTCs Assisted by pCBMA Brushes

    Na Sun, Min Liu, Jine Wang, Zhili Wang, Xinpan Li, Bin Jiang and Renjun Pei

    A chitosan nanofiber substrate grafted with pCBMA brushes is fabricated to provide a 3D interface of porous network and an antifouling flexible space for the immobilized aptamers confronting with cells. The cooperation of pCBMA brushes and DNA aptamers ensures sensitive capture from blood with a considerable purity, and intact release of target cells is realized using a complementary DNA sequence.

  4. Highly Efficient p-i-n Perovskite Solar Cells Utilizing Novel Low-Temperature Solution-Processed Hole Transport Materials with Linear π-Conjugated Structure

    Yang Li, Zheng Xu, Suling Zhao, Bo Qiao, Di Huang, Ling Zhao, Jiao Zhao, Peng Wang, Youqin Zhu, Xianggao Li, Xicheng Liu and Xurong Xu

    Two novel small molecular materials are explored as the hole-transporting layer in p-i-n perovskite solar cells (PSCs), yielding high efficiencies of 17.4% and 17.6%, respectively, which are ≈40% higher than the standard PSCs.

  5. Radially Aligned Electrospun Fibers with Continuous Gradient of SDF1α for the Guidance of Neural Stem Cells

    Xiaoran Li, Mengyuan Li, Jie Sun, Yan Zhuang, Jiajia Shi, Dongwei Guan, Yanyan Chen and Jianwu Dai

    Version of Record online: 21 JUL 2016 | DOI: 10.1002/smll.201601285

    Continuous protein gradients embedded in aligned fibers are developed based on the radially aligned electrospun collagen/poly (ε-caprolactone) fibers. The gradient scaffolds of collagen-binding-domain-fused stromal-cell-derived factor-1α (CBD-SDF1α) direct the migration of neural stem cells toward the center with higher SDF1α content significantly. This class of gradient scaffolds can potentially be employed for nerve regeneration guidance.
