Light‐Controlled Exposure of Cancer Cells to Reactive Oxygen Species Using Organic Semiconductor Thin Films

Advanced Materials Interfaces, EarlyView.
Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...

Crystal Structure and Optical Behavior of Diamino-Substituted 1,4-Benzoquinones

Crystals
Reactions of benzoquinone with amines can potentially lead to the formation of coupled merocyanine or merocyanine/polymethine systems. In this study, several diamino-substituted 1,4-benzoquinones were synthesized.

Fully Inkjet‐Printed Organic Electrochemical Transistors: A Path Toward All‐Organic Electronics

Advanced Materials Technologies, EarlyView.
Fully printed organic electrochemical transistors eliminate the metal electrodes used in conventional printed organic electronics. This work demonstrates the state of the art in three applications using PBFDO and PEDOT:PSS materials: a single‐material strain sensor for real‐time detection of finger flexion, an ion sensor for monitoring aqueous NaCl ...

The Electrochemical Oxidation of Substituted Catechols [PDF]

, 1980
The oxidation of substituted catechols was studied by cyclic voltammetry, chronoamperometry, rotating ring‐disk electrode, and coulometry. The results showed that the quinones that were formed from the oxidation of substituted catechols reacted with the ...

Neutral‐pH Electropolymerization of Aniline on Hierarchically Porous Laser‐Induced Graphene Electrodes for Dual Biosensing

Advanced Materials Technologies, EarlyView.
Neutral‐pH electropolymerization of aniline on laser‐induced graphene (LIG) produces stable, brush‐like polyaniline coatings without requiring acidic conditions. The resulting PANI–LIG electrodes exhibit enhanced electroactive surface area, efficient charge transfer, and dual sensing capability for β‐blockers and pH, providing a scalable platform ...
