Dual Acidic pH‐Responsive Post‐Crosslinked E‐Spun Nanofibrous Scaffolds Exhibiting Enhanced Disassembly and Release for Localized Cancer Treatment

open access: yesAdvanced Healthcare Materials, EarlyView.
Dual acidic pH‐responsive degradable e‐spun nanofibrous mats crosslinked with acid‐labile imine and boronic ester linkages that exhibit rapid degradation and enhanced release of encapsulated anticancer drugs through their acid‐catalyzed hydrolysis and their doxorubicin‐loaded mats having desired antitumoral activity and hemocompatibility, as promising ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

High Charge Carrier Mobility in Non‐Conjugated 3D Covalent Organic Frameworks

open access: yesAdvanced Materials, EarlyView.
A non‐conjugated 3D COF constructed via boronate ester linkages from tetraphenylene and pyrene‐based monomers is reported, which exhibits a high charge carrier mobility of 14 ± 1 cm2 V−1 s−1. ABSTRACT π‐Conjugation, π–π stacking, and long‐range order play a central role in determining charge transport efficiency in organic materials.

Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

open access: yesAdvanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.
