  • Interfacing neurons with artificial functional materials could aid the development of neurological prosthetic devices. Here, primary neurons are incorporated into a polymer layer without adversely affecting their properties; the advance may contribute to the development of artificial retinas.

  • The performance of perovskite-based solar cells has improved dramatically in recent years, yet surprisingly little is known about the details of how they work. Grancini et al. report results that suggest that their behaviour is dominated by the transport of free carriers rather than excitons.

  • Light-sensitive azobenzene compounds can be engineered to stably partition into the plasma membrane, thus causing its thinning in the dark and relaxation upon light stimulation. In neurons, the resulting light-dependent change in membrane capacitance induces a transient hyperpolarization followed by rebound depolarization and action potential firing.

  • Combining discrete molecular junctions to make integrated circuits is a major goal in molecular electronics, but problems with reliability, stability and yield have hindered progress. Researchers have now overcome some of these challenges to simultaneously fabricate 20,000 molecular junctions on a single wafer and connect 200 of them in series.

  • An accurate determination of the size and diffusion length of excitons generated with single-walled nanotubes supports the Wannier–Mott picture of their behaviour, and improves the outlook for the use of nanotubes in optoelectronics and biosensing applications.

  • The structural similarity of organic semiconductors to biological compounds suggests the use of these materials in biomedical applications, yet their implementation is not straightforward. Research in this area is growing fast, thanks to the combined efforts of the multidisciplinary bioelectronics community.

  • From displays to solar cells, the field of organic optoelectronics has come a long way over the past 50 years, but the realization of an electrically pumped organic laser remains elusive. The answer may lie with hybrid organic–inorganic materials called perovskites.

  • Semiconducting polymer nanoparticles can act as light-sensitive interfaces with retinal neurons, and on microinjection in the eye, rescue vision in retinas affected by photoreceptor degeneration, offering a potential new treatment option for inherited retinal dystrophies and late-stage age-related macular degeneration.

  • The morphology of organic thin films has a strong influence on their practical device properties. Farina et al. demonstrate a patterning technique that modifies the conductivity of polymer thin films without affecting their morphology, which could be useful for non-volatile storage applications.

  • Reducing the thickness of flexible electronics is crucial to achieve better conformability and mechanical flexibility. Here, the authors demonstrate all-solution processed OFET with total thickness < 150 nm, with high transparency, which allows the device to conformally adhere onto non-planar surfaces, such as human skin.

  • Degenerative retinal dystrophies, such as retinitis pigmentosa and age-related macular degeneration, lead to blindness owing to the progressive damage of retinal photoreceptors. This Review discusses nanotechnology-based treatment approaches for vision restoration.

  • The standard picture of organic photovoltaics predicts that excitons, which are created under light irradiation, thermalize before dissociation into free electrons and holes. Experimental results and calculations on a low-bandgap polymer–fullerene blend now illustrate the dynamics of hot charge-transfer states and their contribution to charge generation in bulk heterojunctions.

  • 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.
