  • Breath analysis by nanostructured metal oxides as chemo-resistive gas sensors
    Item type: Journal Article
    Righettoni, Marco; Amann, Anton; Pratsinis, Sotiris E. (2015)
    Materials Today
    Recently breath analysis has attracted a lot of attention for disease monitoring and clinical diagnostics as spectrometric techniques of high sophistication and novel sensing materials become available. Here advances in these technologies in connection to breath analysis are critically reviewed. A number of breath markers or tracer compounds are summarized and related to different diseases, either for diagnostics or for monitoring. Emphasis is placed on chemo-resistive gas sensors for their low cost and portability highlighting their potential and challenges for breath analysis as they start to be used in studies involving humans.
  • Graphene nano-heterostructures for quantum devices
    Item type: Journal Article
    Bischoff, Dominik; Eich, Marius; Varlet, Anastasia; et al. (2016)
    Materials Today
    Ten years ago, the exfoliation of graphene started the field of layered two-dimensional materials. Today, there is a huge variety of two-dimensional materials available for both research and applications. The different dimensionality compared to their bulk relatives is responsible for a wealth of novel properties of these layered two-dimensional materials. The true strength of two-dimensional materials is however the possibility to stack different layers on top of each other to engineer new heterostructures with specifically tailored properties. Known as van-der-Waals heterostructures, they enable the experimental observation of a variety of new phenomena. By patterning the individual layers laterally into nanostructures, additional functionality can be added to the devices. This review provides a glimpse at the future opportunities offered by van-der-Waals stacked nanodevices.
  • Structural materials meet synthetic biology in biomedical applications
    Item type: Journal Article
    Zhang, Xiaoxuan; Fussenegger, Martin (2024)
    Materials Today
    This review summarizes recent progress at the confluence of structural biomaterials research and synthetic biology, focusing on biomedical applications involving programmed mammalian cells and bacterial cells. Synthetic biology, which aims to build genetic circuits and bottom-up synthetic networks in microbial and mammalian cells, can benefit greatly from the bio-activity and encapsulation and delivery abilities of structural biomaterials, which can facilitate gene transfection and control of gene switches, as well as cell cultivation and transplantation. Conversely, genetically engineered cells can play roles in the synthesis and modification of structural biomaterials. We discuss the opportunities opened up by this multi-disciplinary interplay, as well as the challenges facing the application of these capabilities for the development of next-generation diagnostic and therapeutic tools.
  • Graphene single-electron transistors
    Item type: Review Article
    Ihn, Thomas M.; Güttinger, J.; Molitor, F.; et al. (2010)
    Materials Today
    Graphene, a single layer of carbon atoms forming a perfectly stable and clean two-dimensional crystal with very few defects, has been proclaimed to be a new revolutionary material for electronics. These hopes rest mainly on the unique band structure properties of graphene. Although living essentially on the surface, electron mobilities in this material do not suffer extensively from surface contaminations and are surprisingly high even at room temperature. In comparison to extremely high quality semiconducting materials, such as Silicon and GaAs, the understanding of electronic transport in graphene is still in its infancy. Research on nanoscale transistors switching with only a single electron exemplifies that there are a number of unresolved problems that material scientists should tackle in the future for making the graphene dreams come true.

  • Oxygen exchange materials for solar thermochemical splitting of H2O and CO2
    Item type: Journal Article
    Scheffe, Jonathan R.; Steinfeld, Aldo (2014)
    Materials Today
    This review summarizes state of the art metal oxide materials used in two-step thermochemical redox cycles for the production of H2 and CO from H2O and CO2 using concentrated solar energy. Advantages and disadvantages of both stoichiometric (e.g. iron oxide based cycles) and nonstoichiometric (e.g. ceria based cycles) materials are discussed in the context of thermodynamics, chemical kinetics, and material stability. Finally, a perspective aimed at future materials development and requirements necessary for advances of process efficiencies is discussed.

  • Chicken egg white: Hatching of a new old biomaterial
    Item type: Journal Article
    Jalili-Firoozinezhad, Sasan; Filippi, Miriam; Mohabatpour, Fatemeh; et al. (2020)
    Materials Today
    Chicken egg white is an abundant, inexpensive and natural source of important proteins such as ovalbumin and lysozyme. Thanks to its bioactivity, easy handling, anti-bacterial activity and biodegradability, egg white is being used since centuries as excipient of poultices for the treatment of various disorders. Owing to unique thermal and electrical features, egg white is currently used in bioplastic development and in fabrication of field-effect transistors, but it could also contribute to various biomedical applications in the future. Indeed, egg white and some of its byproducts were shown to improve tissue engraftment and to stimulate angiogenesis, making it particularly attractive in wound healing and tissue engineering applications. Moreover, egg white can be manipulated to obtain versatile platforms for tridimensional in vitro tissue models or drug delivery systems. This review describes the structure and physicochemical properties of egg white as well as its biological features. It also summarizes fabrication methods from egg white for the generation of functional platforms, and provides a comprehensive overview of the role and performance of egg white in various biomedical applications. Finally, new perspectives for future studies in health with this ancient material are critically discussed.
  • Stability of perovskite materials and devices
    Item type: Review Article
    Weifei, Fu; Ricciardulli, Antonio Gaetano; Akkerman, Quinten A.; et al. (2022)
    Materials Today
    Due to the excellent optoelectronic properties, organic–inorganic perovskites have drawn much attention and have been applied in different electronics with remarkable performance. However, the poor stability creates a massive barrier for the commercialization of perovskite electronic devices. In this review, we discuss intrinsic and extrinsic factors causing instabilities of perovskites and perovskite devices such as solar cells, liquid crystal displays (LCDs), light emitting diodes (LEDs), ionizing radiation detectors, transistors, memristors and sensors. We further review the stabilization approaches, including composition engineering, adoption of lower dimensional compositions, quantum dots, interface engineering, defects engineering and so on.
