    In a schematic of a robust, long-duration TERS imaging technique, a metallic nanotip images several points in a large area of a WS2 monolayer placed on a gold thin film (a). A superposition of two different intensity images, pure WS2 at 422 cm-1 and defect scattering of WS2 at 410 cm-1, reveals a high density of nanoscale protrusions in a large-area far-field confocal Raman image (b). A histogram of the same modes shows a defect density of 5.2% in the WS2 sample (c).
    Advances in tip-enhanced Raman spectroscopy (TERS) can improve spatial resolution and stability, enabling longer imaging and spectroscopic characterization of sub-diffraction-...

    FIGURE 1. The construction of a multichannel fiber photometry system. A light beam from a 488 nm laser is coupled into all multimode fibers simultaneously by an objective. The emitted fluorescence is then collected by the same optical fibers and detected by a sCMOS camera (a). The fiber end faces on the sCMOS camera for the dual-channel mode (b) and four-channel mode (c).
    Increasingly preferred over conventional brain imaging techniques, optical fiber photometry is allowing a better a grasp of the brain’s innerworkings. But this is only the beginning...
