Radical Retention and Functional Stability of Plasma‐Polymerized Nanoparticles for Long‐Term Biofunctionalization

open access: yesAdvanced Materials Interfaces, EarlyView.
Plasma polymerized nanoparticles (PPNs) offer a solvent‐free route to functional nanocarriers with long‐lived radicals. This study establishes design principles for long‐term storage of PPNs, demonstrating that dry‐phase storage retains radical content, covalent reactivity, and bioactivity over extended periods. These findings advance the translational

A Kinetic Monte Carlo Model to Understand Limiting Regimes of Photocurrent and Interfacial Charge Transfer in Organic Semiconductor–Electrolyte Interfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
The interface between a conjugated polymer and phosphate buffer saline is modeled by employing multiphysics kinetic Monte Carlo simulation. Results demonstrate that the Marcus Gerischer theory is inadequate, and particle‐based simulation with molecular Marcus theory is required for accurate modeling.

Cooperative Photocatalysis of 9,10‐Phenanthrenequinone and Sn(OTf)2 for Direct Mannich Reaction of Ethers via Hydrogen Atom Transfer Pathway

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A dual photocatalytic system of o‐PQ and Sn(OTf)2 enables visible light‐induced Mannich‐type addition of ethers to nitrones via Csp³–H activation. This oxidant‐free method offers broad scope and good yields. Mechanistic studies suggest that a photoexcited o‐PQ–Sn(II) complex mediates hydrogen atom transfer to form α‐oxy radicals for nitrone addition. A
