Heat‐ and Light‐Directed Cycloadditions Enable a Pericyclic Cascade Reaction From a Molecular Precursor

Angewandte Chemie, EarlyView.
A multi‐stimuli‐responsive material is designed that responds to light, heat, and mechanical force through distinct chemical reaction pathways. The pathway is directed by self‐assembly and the applied stimulus. A novel pericyclic reaction cascade is also achieved, and the mechanism is supported through density functional theory calculations.

Multifunctional Nanovaccine‐Radiotherapy Synergy Drives Anti‐Tumor Immunity via Multi‐Cascade Cell Death for Pancreatic Cancer Therapy

Advanced Science, EarlyView.
Machine‐learning‐driven transcriptomic analysis identifies FSTL3 as a key tumor‐microenvironment regulator in desmoplastic pancreatic adenocarcinoma. A cRGD‐modified liposome co‐loading gemcitabine and siFSTL3 serves as an irradiation‐triggered in situ nanovaccine. It synergizes with radiotherapy to induce ferroptosis and immunogenic cell death through

Luminescence Vapochromism of a Cu(I)/Na Phosphane Iodide Assembly Based on a Secondary‐Sphere Sodium Response

Angewandte Chemie, EarlyView.
The luminescence of a heterometallic d‐s {Cu2I2Na2} phosphane‐phosphinate aggregate is regulated by an interplay of Na+–π/I– contacts and reversible coordination of oxygen‐containing organic molecules to Na ions. Structural variations caused by the incoming guest lead to a wide and selective variation of the emission color and illustrate a new approach

Sonogenetics Nanomedicine Activates the cGAS‐STING Pathway for Immunotherapy of Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
A HER3‐targeted sonogenetic lipid nanoparticle platform is developed for triple‐negative breast cancer therapy. An AI‐designed miniprotein inhibits HER3 signaling, while TRPV4 and NFAT‐responsive IL‐15 plasmids enable ultrasound‐controlled calcium signaling and cytokine expression. The system induces Ca2+ overload, ROS generation, mitochondrial damage,

Supramolecular Allostery Achieves Tunable Luminescence Aromatic Bridged Phenothiazine Noncovalent Frameworks

Advanced Science, EarlyView.
Tunable luminescent supramolecular organic framework enabled by multiple allosteric effects, composed of a tetracation vinylphenylpyridinium‐modified aromatic‐bridged phenothiazine guest and cucurbit[8]uril, not only exhibits unique guest oxidation‐driven NIR luminescence blue‐shift and effectively enhances the quantum yield by 46‐fold to 22.2% but ...

Self‐Assembled Pt(II) Complexes Boost Up Stem Cell Proliferation and Accelerate Metamorphosis in Living Organisms

Angewandte Chemie, EarlyView.
Pt1, an organometallic platinum‐based complex, act as a modulator of redox homeostasis in cnidarians, regulating cellular functions and life‐cycle dynamics. In Nematostella vectensis, it mitigates oxidative stress, strengthens detox systems and accelerates development.
