    Ultrasmall poly(vinylpyrrolidone)-protected bismuth nanodots are successfully synthesized through an ultrafacile strategy (1 min only under ambient conditions). The nanodots with ultrasmall size (≈2.7 nm) show good biocompatibility both in vitro and in vivo, which can be used for X-ray computed tomography (CT) and photothermal imaging. The above two imaging modalities can effectively guide the photothermal therapy process of nanodots.

    Stable MAPbBr3 crystals with different sizes are successfully localized on a flat substrate via laser-induced heating of the liquid precursors. By adjusting the infrared laser parameters, luminescent arrays and photoconductive wires are grown on-site. This technique can be used to guide the writing of other patterns for specific functionalities.

  3. Transferred, Ultrathin Oxide Bilayers as Biofluid Barriers for Flexible Electronic Implants

    Enming Song, Yoon Kyeung Lee, Rui Li, Jinghua Li, Xin Jin, Ki Jun Yu, Zhaoqian Xie, Hui Fang, Yiding Zhong, Haina Du, Jize Zhang, Guanhua Fang, Yerim Kim, Younghee Yoon, Muhammad A. Alam, Yongfeng Mei, Yonggang Huang and John A. Rogers

    Ultrathin, transferred oxide bilayers that are impermeable to both water and ions serve as compatible biointerfaces and robust biofluid barriers with multidecade lifetimes. An optimized strategy exploits a hafnium oxide layer formed by atomic layer deposition on a thermal silicon dioxide layer, both on top of flexible electronics. The findings offer relevance to diverse ranges of biointegrated implantable devices.

  4. Inorganic Acid-Impregnated Covalent Organic Gels as High-Performance Proton-Conductive Materials at Subzero Temperatures

    Covalent organic gels (COGs) can serve as a type of new subzero-temperature proton-conductive material. The COGs not only show high proton conductivities and excellent long-term stability over the temperature range of −40 to 60 °C, but also possess remarkable self-sustaining nature and superior processability.

  5. ATP-Responsive Aptamer-Based Metal–Organic Framework Nanoparticles (NMOFs) for the Controlled Release of Loads and Drugs

    Stimuli-responsive DNA-functionalized metal–organic framework nanoparticles (NMOFs): The synthesis of NMOFs loaded with doxorubicin and capped with stimuli-responsive DNAs that respond to biomarkers characteristic to cancer cells is described. By locking the drug-loaded NMOFs with a DNA strand consisting of the AS1411 aptamer and the ATP aptamer, targeted permeation of the NMOFs into cancer cells, the ATP-driven unlocking of the NMOFs, and drug release are demonstrated.
