Stress Accumulation Induced by Ion Exchange for Synchronous Modulation of Mode and Wavelength in Microlasers

open access: yesAdvanced Science, EarlyView.
This work demonstrates a paradigm‐shifting strategy to simultaneously achieve broadband wavelength tunability and single‐mode control within a single perovskite microwire structure. Using a facile heating‐assisted solid–solid anion‐exchange strategy, we synthesized phase‐pure CsPbClxBr3‐x microwires that exhibit the widest reported continuous lasing ...

Adaptive Coordination Engineering for Efficient and Robust H2 Release

open access: yesAdvanced Science, EarlyView.
β‐H elimination is a pivotal but challenging step in homogeneous formic acid dehydrogenation reactions due to strict hydride‐metal matching. By using a rationally designed Pd1Ag2 bimetallic system with adaptive Pd1‐Ag2/L2 coordination and formate bridges, it enables boosted formic acid dehydrogenation under ambient air (7.7 times higher than a Pd ...

Unconventional Room‐Temperature Antisymmetric Magnetoresistance in van der Waals Fe3GaTe2/Pt Heterostructures

open access: yesAdvanced Science, EarlyView.
We investigated a special electrical phenomenon, known as antisymmetric magnetoresistance with four distinct resistance states, in 2D Fe3GaTe2/Pt devices at room temperature. By designing devices with two separated magnetic nanoflakes, we confirmed that the effect originates from spin–momentum locking rather than magnetic domain walls or interface ...

Membrane Fusion‐Mediated Cytosolic Delivery of Threose Nucleic Acids via Homotypic Nanoparticles Overcomes Drug Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study introduces a biomimetic “nanofusion” platform that integrates the biostability of threose nucleic acids (TNA) with homotypic cell‐membrane cloaking to combat drug‐resistant TNBC. By leveraging a non‐canonical membrane‐fusion pathway for direct cytosolic delivery, the platform bypasses endosomal sequestration. To achieve potent AKT2 silencing

Biomimetic Macrophage Cell Membrane‐Based Nanoparticles for Effective Treatment of Glioblastoma Through Boron Neutron Capture Therapy Combined With Immunotherapy

open access: yesAdvanced Science, EarlyView.
ABSTRACT Glioblastoma multiforme (GBM) remains largely incurable due to the blood‐brain barrier (BBB) and immunosuppressive microenvironment. While boron neutron capture therapy (BNCT) selectively eradicates tumor cells via 10B(n, α)‐7Li reactions, its clinical potential in GBM is unrealized because of the suboptimal pharmacokinetics of conventional ...

Multi‐Component Functionalized Bifidobacterium Longum Hydrogel for Multi‐Target Integrated Therapy of Colitis‐Associated Anxiety and Depression

open access: yesAdvanced Science, EarlyView.
A pH/MMP dual‐responsive Bifidobacterium longum (BL) hydrogel (INPs@BL@Gel) functionalized with baicalin, tyrosine, and inulin is constructed. It enables gastric protection, inflammation‐targeted release, and prolonged intestinal colonization. By remodeling gut microbiota, elevating beneficial neuroactive metabolites (homovanillic acid, short‐chain ...

Optimizing Stratification in Binary Colloidal Supraparticles

open access: yesAdvanced Science, EarlyView.
Supraparticles from binary particle populations show stratification when dried at high Péclet numbers. In spray‐dried systems at high initial particle concentration and fast drying conditions optimal combinations of particle size ratios and volume fractions that produce maximal stratification are found both in experiment and simulation, contrasting the

Nano‐Backpack Engineered Probiotics with Reactive Oxygen Species–Responsive Tungsten Release for Synergistic Therapy of Inflammatory Bowel Disease

open access: yesAdvanced Science, EarlyView.
An integrated probiotic system is engineered to execute a programmed therapeutic cascade against inflammatory bowel disease. Upon pathological signals, the system sequentially performs ROS scavenging, tungsten release, and selective pathogen suppression, thereby breaking the oxidative stress–dysbiosis cycle to remodel gut microbiota and reinforce ...
