Photostability of Cyanine Dyes and Its Correlation to Their Photothermal and Photodynamic Effects

Chemistry – A European Journal, EarlyView.
Photostability (PS) of dyes is a crucial parameter for performance in biological applications, yet often underrated. Here PS of several cyanines is investigated. The method is carefully evaluated and designed as a general and easy tool to compare PS of NIR dyes.

All‐in‐One Intelligent Hemostatic Sponge: Rapid Hemostasis for Non‐Compressive Wounds With Synergetic Enhanced Antibacterial Efficacy and Self‐Reporting Biodegradation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Clinicians often concurrently tackle critical challenges including emergency hemorrhage, secondary infection, and the elusive tracking of biodegradation of conventional hemostatic agents for complex wounds. Here, we report an intelligent hemostatic sponge (spCS@AIE) by incorporating aggregation‐induced emission (AIE) nanoparticles with short‐wave ...

Optimized Coherence Masking Improves Ultrasound Imaging of Kidney Cysts

Journal of Ultrasound in Medicine, EarlyView.
Objectives Renal cystic lesions are exceedingly common and typically benign, though accurate diagnostic techniques are required to recognize the subset of malignant lesions that require timely intervention. Ultrasound (US) is the preferred first line test for renal cyst evaluation because it is safe, widely accessible, and low cost. US imaging, however,
