Semiconducting Polymer Nanoparticles Enable Light‐Controlled Bidirectional Modulation of Nitric Oxide in Endothelial Cells

open access: yesAdvanced Science, EarlyView.
Bimodal modulation of nitric oxide in endothelial cells is achieved by light‐sensitive polymer nanoparticles. In dark, P3HT/PEDOT:PSS NPs boost intracellular ·NO, upregulate both endothelial and induced nitric oxide synthase, and drive a metabolic shift toward glycolysis.

Engineered TIGIT‐Blockade Membrane Vesicles Synergize with Microwave Ablation to Mediate Liver Metastases Eradication

open access: yesAdvanced Science, EarlyView.
Microwave ablation (MWA) represents a highly effective and clinically significant therapeutic modality for the treatment of liver metastases. This study develops engineered cell membrane vesicles to specifically target the transition zone of MWA for liver metastases. This strategy can inhibit VEGF‐mediated immunosuppression, block CD155/TIGIT signaling

Understanding Glioblastoma Dynamics Using 3D Organoids and Engineered Extracellular Matrix

open access: yesAdvanced Science, EarlyView.
A modular in vitro glioblastoma multiforme (GBM) model combining patient‐derived glioma stem‐like cells (GSC) organoid with an engineered extracellular matrix (eECM) and endothelial co‐culture enhances differentiation and GBM associated gene expression.

Deciphering the Evolution Pattern of Structural Variations Overlapped With Repetitive Sequence During Cattle Evolution

open access: yesAdvanced Science, EarlyView.
The authors complement bovine pan‐SV with massive novel structural variations (SVs) identified through long‐read sequencing of 83 globally distributed cattle breeds. Repetitive sequence‐mediated SVs (rep‐SV) exhibit distinct dynamic patterns throughout cattle sub‐speciation and/or domestication processes, including uneven distribution between chr‐X and

Mechanically Robust Biodegradable Stents With Theragenerative Vascular Responses via Combined 3D Printing and Janus Nanoengineering

open access: yesAdvanced Science, EarlyView.
This work introduces a theragenerative 3D‐printed biodegradable stent with Janus nanoarchitecture for spatially controlled vascular healing. A luminal tantalum ion–implanted surface accelerates endothelialization and hemocompatibility, while an abluminal sirolimus/poly‐L‐lactic acid–tantalum layer provides sustained drug release and suppresses smooth ...

Tracking of [14C]Polystyrene Nanoplastics in Pregnant Mice

open access: yesAdvanced Science, EarlyView.
This study investigates [14C]polystyrene nanoplastic ([14C]PS) translocation in late‐stage pregnant mice after intranasal (0.5 mg of [14C]PS on GD12, GD14, and GD16, n = 6) and intravenous administration (1.5 mg of [14C]PS on GD16, n = 6). 14C‐radiolabel allows quantitative tracking of unmodified polystyrene nanoplastics.

Targeted Thrombolysis via CCR2‐Engineered Macrophage‐Mimicking Microbubbles Safely Ablates Venous, Arterial, and Microvascular Thrombosis

open access: yesAdvanced Science, EarlyView.
CCR2‐Enhanced Macrophage Membrane–Camouflaged Microbubbles for MCP‐1–Mediated Thrombus Targeting and Ultrasound‐Triggered Urokinase Release. ABSTRACT The clinical management of thrombosis, a primary cause of death worldwide, is hampered by the limitations of current thrombolytic agents, including short half‐life and high risk of off‐target bleeding ...

Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.
