    Air- and moisture-resistivity as well as chemical stability are key issues for organic electronics and thus, influence the operational lifetime of devices. The hydrogen-bonded pigment quinacridone is an example for extraordinary chemical stability. Here, spectroscopic studies on quinacridone as compared to pentacene thin-films confirm different spectral response of their radical cations, emphasizing the stability on quinacridone.

  2. Metal/Polymer Based Stretchable Antenna for Constant Frequency Far-Field Communication in Wearable Electronics

    A flexible and stretchable antenna, enabled by out-of-plane stretching and fabricated using a low-cost metal (copper), demonstrates constant frequency operation for far-field communication—up to 80 m on a human arm at 1.25 mW transmission power.

  3. Infrared Aluminum Metamaterial Perfect Absorbers for Plasmon-Enhanced Infrared Spectroscopy

    Infrared aluminum metamaterial perfect absorbers (MPAs) are fabricated using scalable and cost-effective colloidal lithography and dry etching. The plasmon resonances can be readily tuned by the etching time of polystyrene spheres. Chemical surface functionalization of the MPAs is achieved using phosphonic acid making it possible to use Al for surface enhanced infrared absorption spectroscopy.

  4. PbS/CdS/ZnS Quantum Dots: A Multifunctional Platform for In Vivo Near-Infrared Low-Dose Fluorescence Imaging

    Antonio Benayas, Fuqiang Ren, Elisa Carrasco, Vicente Marzal, Blanca del Rosal, Belete A. Gonfa, Ángeles Juarranz, Francisco Sanz-Rodríguez, Daniel Jaque, José García-Solé, Dongling Ma and Fiorenzo Vetrone

    Low-dose in vivo near-infrared (NIR) fluorescence imaging is achieved by using carefully designed PbS/CdS/ZnS quantum dots (QDs), intensely emitting within the second biological window (1000–1350 nm). Moreover, preliminary studies both in vitro and in vivo have proven the lack of noticeable toxicity of these QDs. As an additional advantage, this NIR-fluorescence imaging platform has demonstrated useful multifunctionality, thus being capable, both ex vivo and in vitro, of high-resolution thermal sensing in the physiological temperature range.

  5. Development of Synthetic Platelet-Activating Hydrogel Matrices to Induce Local Hemostasis

    A synthetic hemostatic hydrogel system which avoids the use of thrombin, but allows platelet activation and shortens bleeding time in a localized fashion, is introduced. The thrombin receptor agonist peptide is, upon UV irradiation, covalently attached on biocompatible polyvinyl alcohol hydrogels via facile photoclick conjugation, demonstrating the utility of this system for hemorrhage control and potential medical applications.
