Nanobody‐Conjugated Theranostic Prodrug Targeting αvβ3 Integrin Enables Precision Cancer Therapy With Real‐Time Imaging

open access: yesAdvanced Healthcare Materials, EarlyView.
The image shows a schematic form a nanobody‐conjugated theranostic prodrug (NBD) platform targeting tumor‐associated αvβ3 integrin. The NBD system integrates selective nanobody‐mediated tumor recognition, glutathione‐responsive disulfide cleavage for doxorubicin release, and aza‐BODIPY‐based near‐infrared fluorescence for real‐time imaging.

Platelet-activating factor stimulates sodium-hydrogen exchange in ventricular myocytes

open access: yesAmerican Journal of Physiology-Heart and Circulatory Physiology, 2011
Sodium-hydrogen exchanger (NHE), the principal sarcolemmal acid extruder in ventricular myocytes, is stimulated by a variety of autocrine/paracrine factors and contributes to myocardial injury and arrhythmias during ischemia-reperfusion. Platelet-activating factor (PAF; 1- o-alkyl-2-acetyl- sn-glycero-3-phosphocholine) is a potent proinflammatory ...

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.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

open access: yesAdvanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems
