    Living photovoltaics

    Artificial nanomaterials, such as carbon nanotubes, can enhance living cells’ natural capabilities or even impart them with artificial properties unfounded in nature, which are inherited when cells divide. This artistic representation depicts a filament of cyanobacteria cells from Nostoc sp. The nanobionic cells, shown in purple, contain nanotubes that allow them to emit a powerful electric current, shown at the forefront of the image. The nanobionic cells can be tracked over several generations through near-infrared imaging.

    Mapping RNA modifications with nanopore

    This artistic representation depicts direct single molecule identification of major RNA epigenetic modifications using a phenylboronic acid modified Mycobacterium smegmatis porin A nanopore. This highly engineered nanopore demonstrates an outstanding resolution, suitable for sensing of a large variety of nucleoside or nucleotide derivatives simultaneously.

    Treating sepsis with nanoparticles

    Artistic representation of NAD(H)-loaded nanoparticles to replenish intracellular NAD(H) pool. NAD(H) are potential immunomodulators, but they cannot diffuse across the cell membrane, which hinders their clinical applications. Direct intracellular NAD(H) delivery enabled by nanoparticles can improve cellular energy supply and prevent inflammation-induced cell pyroptosis and apoptosis, thereby reducing fatality in severe sepsis by maintaining immune and vascular homeostasis.

    Stimulating single photon source

    The artificially coloured scanning electron microscope image shows an ensemble of deterministically coupled micropillar cavities. Fast laser pulses, which induce stimulated emission, can remove time jitter and thereby further improve the characteristics of these bright solid-state quantum light sources.

    Nanotubes bridge cancer and immune cells

    The image is an artistic representation depicting cancer cells physically connecting to T cells through nanotubes. Cancer cells harvest mitochondria from T cells. Inhibiting this mechanism can augment the immune response against cancer cells.
