  • Clinical translation of nanoparticles for neural stimulation
    Nat. Rev. Mater. (IF 71.189) Pub Date : 2020-11-23
    Fabio Benfenati; Guglielmo Lanzani

    Nanoparticles enable wireless neural stimulation without the need for genetic manipulation. However, challenges remain for their potential application in the cure of human neurodegenerative diseases. A careful analysis of the different nanomaterials and energy sources that proved effective in animal models will direct their clinical translatability.

Scalable fabrication technologies that enable control over construct architecture at multiple length scales

  • Self-healing polymers
    Nat. Rev. Mater. (IF 71.189) Pub Date : 2020-06-05
    Siyang Wang; Marek W. Urban

    Self-healing is the capability of a material to recover from physical damage. Both physical and chemical approaches have been used to construct self-healing polymers. These include diffusion and flow, shape-memory effects, heterogeneous self-healing systems, covalent-bond reformation and reshuffling, dynamics of supramolecular chemistry or combinations thereof. In this Review, we discuss the similarities

  • Hidden, entangled and resonating order
    Nat. Rev. Mater. (IF 71.189) Pub Date : 2020-06-04
    Gabriel Aeppli; Alexander V. Balatsky; Henrik M. Rønnow; Nicola A. Spaldin

    In condensed matter systems, the atoms, electrons or spins can sometimes arrange themselves in ways that result in unexpected properties but that cannot be detected by conventional experimental probes. Several historical and contemporary examples of such hidden orders are known and more are awaiting discovery, perhaps in the form of more complex composite, entangled or dynamical hidden orders.

  • Theoretical insights into the surface physics and chemistry of redox-active oxides
    Nat. Rev. Mater. (IF 71.189) Pub Date : 2020-05-27
    Roger Rousseau; Vassiliki-Alexandra Glezakou; Annabella Selloni

    Redox-active oxides find use in many applications, including catalysts, photovoltaic devices, self-cleaning glasses, chemical sensors and electronic components. Their utility derives from their unique ability to access multiple metal-charge states within a finite energy window. However, this property also confounds our ability to study reducible oxides, because it leads to structural, compositional

  • Synthetic alternatives to Matrigel.
    Nat. Rev. Mater. (IF 71.189) Pub Date : 2020-05-27
    Elizabeth A Aisenbrey,William L Murphy

    Matrigel, a basement-membrane matrix extracted from Engelbreth–Holm–Swarm mouse sarcomas, has been used for more than four decades for a myriad of cell-culture applications. However, Matrigel is limited in its applicability to cellular biology, therapeutic-cell manufacturing and drug discovery, owing to its complex, ill-defined and variable composition. Variations in the mechanical and biochemical

  • Detect and deliver
    Nat. Rev. Mater. (IF 71.189) Pub Date : 2020-05-26
    Alison Stoddart

    An article in Science Advances reports a wireless smart contact lens for diabetic diagnosis and the delivery of drugs to treat diabetic retinopathy.

  • Journey to the core of the Earth
    Nat. Rev. Mater. (IF 71.189) Pub Date : 2020-05-20
    Giulia Pacchioni

    An article in Physical Review Letters reports the properties of iron — the main element in the Earth’s core — at extreme temperatures and pressures, providing clues to the core’s composition.
