Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

Advanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Mitochondria‐Targeted Nanomotor: H2S‐Driven Cascade Therapy for Hepatocellular Carcinoma

Advanced Materials, EarlyView.
A mitochondrial‐targeted nanomotor integrates photodynamic therapy, mild photothermal therapy, and enzyme dynamic therapy into a self‐amplifying cascade through H2S‐driven metabolic reprogramming. Abstract Despite advances in combination therapies for cancer treatment, most strategies rely on modular‐additive designs that lack dynamic molecular cues to
