Abstract
Psoriasis is a chronic skin inflammation characterized by dysregulated crosstalk between immune cells and keratinocytes. Here we show that the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway is a key regulator of psoriatic inflammation in a mouse model. Platinum-doped positively charged carbon dots (Pt-CDs) were designed to inhibit the cGAS-STING pathway. By inhibiting the cGAS-STING pathway with Pt-CDs, the secretion of proinflammatory cytokines in macrophages was reduced, and the proinflammatory cytokines-induced breakdown of immunological tolerance and overexpression of chemokines in keratinocytes was restored, which reversed the homeostatic imbalance through breaking these cytokines-mediated intercellular positive feedback loop. Topical Pt-CDs treatment exhibited therapeutic effects in imiquimod-induced psoriasis mice without noticeable toxicity. The reversal of elevated expression of STING, phosphorylated STING, and downstream genes within psoriatic lesions indicates that Pt-CDs effectively inhibit the cGAS-STING pathway. This work suggests a promising strategy for psoriasis treatment by targeting the cGAS-STING pathway with Pt-CDs nanoinhibitor to restore skin homeostatic balance.

Abstract
All-perovskite tandem solar cells offer the potential to surpass the Shockley-Queisser (SQ) limit efficiency of single-junction solar cells while maintaining the advantages of low-cost and high-productivity solution processing. However, scalable solution processing of electron transport layer (ETL) in p-i-n structured perovskite solar subcells remains challenging due to the rough perovskite film surface and energy level mismatch between ETL and perovskites. Here, scalable solution processing of hybrid fullerenes (HF) with blade-coating on both wide-bandgap (≈1.80 eV) and narrow-bandgap (≈1.25 eV) perovskite films in all-perovskite tandem solar modules is developed. The HF, comprising a mixture of fullerene (C60 ), phenyl C61 butyric acid methyl ester, and indene-C60 bisadduct, exhibits improved conductivity, superior energy level alignment with both wide- and narrow-bandgap perovskites, and reduced interfacial nonradiative recombination when compared to the conventional thermal-evaporated C60 . With scalable solution-processed HF as the ETLs, the all-perovskite tandem solar modules achieve a champion power conversion efficiency of 23.3% (aperture area = 20.25 cm2 ). This study paves the way to all-solution processing of low-cost and high-efficiency all-perovskite tandem solar modules in the future.

Abstract
Macrophage phagocytosis of tumor cells has emerged as an attractive strategy for tumor therapy. Nevertheless, immunosuppressive M2 macrophages in the tumor microenvironment and the high expression of anti-phagocytic signals from tumor cells impede therapeutic efficacy. To address these issues and improve the management of malignant tumors, in this study we developed a gene-editable palladium-based bioorthogonal nanoplatform, consisting of CRISPR/Cas9 gene editing system-linked Pd nanoclusters, and a hyaluronic acid surface layer (HBPdC). This HBPdC nanoplatform exhibited satisfactory tumor-targeting efficiency and triggered Fenton-like reactions in the tumor microenvironment to generate reactive oxygen species for chemodynamic therapy and macrophage M1 polarization, which directly eliminated tumor cells, and stimulated the antitumor response of macrophages. HBPdC could reprogram tumor cells through gene editing to reduce the expression of CD47 and adipocyte plasma membrane-associated protein, thereby promoting their recognition and phagocytosis by macrophages. Moreover, HBPdC induced the activation of sequestered prodrugs via bioorthogonal catalysis, enabling chemotherapy and thereby enhancing tumor cell death. Importantly, the Pd nanoclusters of HBPdC were sufficiently cleared through basic metabolic pathways, confirming their biocompatibility and biosafety. Therefore, by promoting macrophage phagocytosis, the HBPdC system developed herein represents a highly promising antitumor toolset for cancer therapy applications.

Abstract
Multijunction tandem solar cells offer a promising route to surpass the efficiency limit of single-junction solar cells. All-perovskite tandem solar cells are particularly attractive due to their high power conversion efficiency, now reaching 28% despite being made with relatively easy fabrication methods. In this review, we summarize the progress in all-perovskite tandem solar cells. We then discuss the scientific and engineering challenges associated with both absorbers and functional layers and offer strategies for improving the efficiency and stability of all-perovskite tandem solar cells from the perspective of chemistry.

Abstract
DNA origami technology has rapidly developed into an ideal means to programmably crystallize nanoparticles. However, most existing DNA origami three-dimensional platforms normally used a single type of DNA origami unit, which greatly limits the types of nanoparticle superlattices that can be synthesized. Here, we report a universal strategy to vastly enrich the library of nanoparticle superlattices, based on multiple-unit (≥4 units) DNA origami platforms, which were constructed by programmably cocrystallizing three different DNA origami octahedral "homologs." Through selectively inserting nanoparticles into DNA origami monomers, numerous nanoparticle superlattices can be synthesized on the basis of the same platform. In this work, we obtained 85 types of DOF/AuNP (DNA origami frame/gold nanoparticle) superlattices using three different DNA origami platforms as examples. We believe that our strategy can provide possible access to fabricate virtually endless types of nanoparticle superlattices and promote the construction of functional materials with special properties.
