Development of Sub‐50 nm Core–Shell Silica Nanoparticles With Controlled In Vivo Behavior for 19F Magnetic Resonance Imaging

Angewandte Chemie, EarlyView.
Ultrasmall PFCE‐loaded silica nanoparticles synthesized through a one‐pot double‐emulsion synthesis method, where rapid silica shell formation kinetically fixes droplet size. The resulting s‐FLAME nanoparticles enable strong 19F MRI signals with enhanced hepatic clearance rate and tumor‐accumulation performance. ABSTRACT 19F magnetic resonance imaging (

Comparison of Receptor‐Mediated Endocytosis and Its Application to Enhance DNA Transfection by TFAMoplex

Advanced NanoBiomed Research, EarlyView.
We developed an assay to distinguish cellular binding from internalization. Compatible with microscopy and high‐throughput screening, the method identifies ligand‐mediated uptake. Applying top candidates to a protein‐based DNA carrier enhanced transfection efficiency, providing a rational strategy to improve non‐viral gene delivery systems.

Thermostable Bioluminescent Intercalating Dyes for Real‐Time, Integrated Nucleic Acid Amplification and Detection

Angewandte Chemie, EarlyView.
We present a bioluminescent diagnostic platform that integrates DNA amplification and detection in a single step. The engineering of thermostable luciferase‐intercalating dye conjugates and controlled release of caged luciferin substrates enable real‐time, detection of attomolar concentrations of viral DNA within 30 min.

Auf dem Weg zu chromoselektiven Transformationen in biologischen Systemen: Perspektiven und Herausforderungen

Angewandte Chemie, EarlyView.
Die Kontrolle biologischer Systeme mit organischen Chromophoren hat sich zu einer vielversprechenden Strategie entwickelt und findet Anwendung von der chemischen Biologie bis hin zur Medizin. Die Komplexität von In‐vivo‐Systemen lässt sich jedoch nicht mit nur einer einzigen Lichtwellenlänge adäquat abbilden.

Perilipin‐2‐Anchored Lipid Droplet‐Targeting Phototheranostics

Angewandte Chemie, EarlyView.
This study reports two NIR theranostic dyes, C‐BDP‐OH and C‐BDP‐OMe. C‐BDP‐OMe targets lipid droplets via a dual‐anchoring mechanism with PLIN2, enabling wash‐free tumor imaging. With 62.6% photothermal conversion efficiency, it achieves tumor ablation by downregulating PLIN2, disrupting LD‐mitochondria crosstalk, and triggering apoptosis and ...

Mitochondria‐Targeting Moieties Based on N‐Tethered Pyridinium Cations

Angewandte Chemie, EarlyView.
Pyridinium cations were benchmarked as mitochondria‐targeting moieties in a panel of N‐tethered fluorescent‐, bioactive‐, and inert‐cargo conjugates. 3,5‐Diphenylpyridinium (DPPy+) is a competent triphenylphosphonium (TPP+) surrogate, combining high mitochondria‐targeting efficiency with lower intrinsic effects on mitochondrial function.
