The double closed-ring isomer of a diarylethene fused dimer was synthesized by a combination of photochemical and oxidative cyclization reaction. The double closed-ring isomer of a diarylethene fused dimer has fixed π-conjugation in a rigid planar framework so that this compound has been long-desired. However, with respect to the photocyclization of a diarylethe...
Continue readingIn chiral hybrid perovskites (CHPs), the generation of polarized spin current and the manipulation of spin exciton recombination are expected to produce circularly polarized electroluminescence (CP-EL) through chiral-induced spin selectivity (CISS). It opens a new avenue for developing single junction spin light-emitting diodes (spin-LEDs). The recent challenge l...
Continue readingThe nuclear envelope serves as a highly regulated gateway for macromolecule exchange between the nucleus and cytoplasm in eukaryotes. Here we have developed a cell nucleus-mimicking polymeric membrane-enclosed system for long and self-regulated therapy. A polymeric nano-membrane with nanopores is conformally synthesized in situ on the surface of each insulin crys...
Continue readingDynamic and reversible manipulation of circularly polarized luminescence (CPL) in soft materials is highly desirable for advanced chiroptical devices, information encryption, and labeling technology. However, this remains a formidable challenge in circularly polarized organic ultralong room-temperature phosphorescence (CP-OURTP) materials. Herein, a bilayered chi...
Continue readingHybrid lead halide materials have been highly studied for optoelectronics, but their use with chiral organics in chiro-optoelectronics remains limited. Understanding the ability to impart chirality into bulk materials by incorporating a chiral precursor is of great interest due to unique optical properties directly arising from chirality such as circular dichroism,...
Continue readingBreast cancer remains the second most common cause of cancer-related deaths in women worldwide, with ≈70% of cases linked to the overexpression of Estrogen Receptor (ERα). Existing imaging tools often fail to reliably differentiate between ER-positive and ER-negative cancer cells. To address this limitation, two novel fluorescent probes, E2N and E2R, ...
Continue readingTimely control of bleeding is crucial to reduce mortality in traumatic injuries, highlighting the urgent need for biomaterials with anti-hemorrhagic properties. Polycaprolactone (PCL) is commonly used for producing nanofibers in the range of 100–200 nm. However, creating ultrafine PCL nanofibers with diameters below 100 nm remains a challenge, limiting its ...
Continue readingPrecisely capturing and manipulating microscale objects, such as individual cells and microorganisms, is fundamental to advancements in biomedical research and microrobotics. Photoactuators based on optical fibers serving as flexible, unobstructed waveguides are well-suited for these operations, particularly in confined locations where free-space illumination is ...
Continue readingThe Co-free Li[Ni0.75Mn0.25]O2 (NM7525) cathode offers the significant advantage of low production costs. However, it requires a high-voltage charging process (≥4.5 V vs Li/Li⁺) to achieve the energy density level of high-Ni Li[NixCoyMnz]O2 (x ≥ 0.8) cathodes, which leads to severe structural and morphological degradation in the secondary particles during p...
Continue readingNanomedicine based brain targeting strategies have emerged as a promising avenue for ischemic stroke (IS) treatment. However, conventional targeting approaches face significant challenges in manipulating biodistribution and achieving efficient brain targeting to attain adequate therapeutic effects. Here, this limitation is overcame by developing a magnetic field ...
Continue readingMolecules with nitrogen–nitrogen (N–N) bonds include diverse specialized metabolites from nature, but little is known about the underlying enzymatic mechanisms that have evolved for N–N bond formation. To directly form a single N(sp3)–N(sp3) bond, enzymes must reverse the typical nucleophilicity of one nitrogen. Here we report the structure ...
