Regulating Enzyme Activity via Microaggregates Mediated by Phase Separation

open access: yesAdvanced Science, EarlyView.
An enzyme‐sequestration strategy for combating postoperative pancreatic fistula (POPF) is developed, employing a D‐peptide called DPMD to induce liquid–solid phase separation (LSPS) of pancreatic proteases. This LSPS‐driven microaggregate approach effectively isolates trypsin and chymotrypsin from their substrates, thereby reducing pancreatic fluid ...

Facile Single‐Nanocomposite 4D Bioprinting of Dynamic Hydrogel Constructs with Thickness‐Controlled Gradient

open access: yesAdvanced Science, EarlyView.
This study presents a novel and facile thickness‐modulated 4D bioprinting approach using a smart bioink made of gelatin, GelMA, and MXene. Leveraging computational models, it creates living constructs with programmable unidirectional and bidirectional curvatures under a single UV exposure.

A Single‐Component Adhesive Sponge Based on Blood‐Triggered and Autopenetrative Adhesion for Robust Vascular Closure

open access: yesAdvanced Science, EarlyView.
This study presents MonoSeal, a single‐component adhesive sponge powered by the novel Autopenetrative Adhesion (APA) mechanism. Unlike traditional adhesives, which require external stimuli, APA enables strong tissue adhesion under dynamic, high‐pressure bleeding conditions. MonoSeal's ability to autonomously seal large‐size arterial defects underscores

A Multifunctional Molecular Probe for Multimodal Imaging‐Guided Potent Photothermal/Photodynamic Therapy of Endometriosis

open access: yesAdvanced Science, EarlyView.
The cRGD‐ILD molecular probe integrates clinically available components: a cRGD peptide (integrin αvβ3 targeting), ICG (for fluorescence/photoacoustic imaging and phototherapy), and Gd‐DTPA (MRI contrast). Utilizing small size and receptor targeting, it achieves selective lesion accumulation.
