Nanophotonic waveguides that implement long optical pathlengths on chips are promising for enabling miniaturized spectroscopic sensors for widespread IoT applications. Here, an all-dielectric metamaterial-assisted comb waveguide was developed. It possesses an extraordinary external optical field confinement, outperforming free-space optics with superior light‒matter interaction.

An autonomously self-healing and intrinsically stretchable supercapacitor in all-climate environments is constructed based on universally self-healable organohydrogel electrodes with record-high temperature-invariant conductivity. Owing to the hierarchical conducting structure and multiple dynamic interactions, the assembled supercapacitor exhibits instantaneous and complete capacitance recovery and real-time mechanical self-healing over a wide temperature range.

The picture shows an artist's view of fluorescence lifetime super-resolution microscopy. In our manuscript, we directly compare performances of the two detector types featuring single-molecule sensitivity: the lifetime camera (Photonscore LINCam25) shown on the right-hand side of the picture, and a single-photon counting module (Excelitas SPCM-AQRH) shown on the left-hand side. The robotic arms holding detectors and a flask reflect our passion to automation of an acquisition process, aiming towards further development of high-throughput super-resolution bioimaging. In our investigation we used multiplexed imaging of single cells, therefore the detectors are directed to a single cell, while the other cells are waiting to be imaged. A solution including DNA molecules poured from the Erlenmeyer flask onto a cell reflects the fact that we used DNA-PAINT to image two cellular targets (mitochondria and peroxisomes), as shown in the real super-resolved image incorporated into a cell bottom. DNA-PAINT is a powerful super-resolution technique based on transient binding of short single-stranded DNA labeled with fluorophores (shown inside the flask) to its complementary strands (not shown), which are in turn conjugated to cellular targets.

图为荧光寿命超分辨率显微镜的艺术家视角。 在我们的手稿中,我们直接比较了两种具有单分子灵敏度的探测器类型的性能:图片右侧显示的寿命相机 (Photonscore LINCam25) 和单光子计数模块 (Excelitas SPCM-AQRH) 如左图所示。 持有探测器和烧瓶的机械臂反映了我们对采集过程自动化的热情,旨在进一步开发高通量超分辨率生物成像。 在我们的研究中,我们使用了单细胞的多重成像,因此探测器被定向到单个细胞,而其他细胞正在等待成像。 包含从锥形瓶倒入细胞中的 DNA 分子的溶液反映了我们使用 DNA-PAINT 对两个细胞目标(线粒体和过氧化物酶体)进行成像的事实,如合并到细胞底部的真实超分辨率图像所示。 DNA-PAINT 是一种强大的超分辨率技术,基于荧光团标记的短单链 DNA(显示在烧瓶内)与其互补链(未显示)的瞬时结合,而互补链又与细胞靶标缀合。
