Sensitive and Spatially‐Resolved Electrochemiluminescence via Micropatterning

Advanced Materials Interfaces, EarlyView.
The use of a simple silica nanoparticle surface coating and patterning process can transform ordinary gold electrodes into multiplexed ECL sensing electrodes. Through spatially confined droplet formation and local ECL emission, it is possible to perform multiple analyses simultaneously from individual locations as well as intensify the ECL signal by as

Minimally Invasive Delivery of Optical Nanosensors Using Injectable Hydrogels

Advanced Materials Interfaces, EarlyView.
Injectable peptide hydrogels offer a minimally invasive delivery platform for single‐walled carbon nanotube (SWCNT)‐based near‐infrared fluorescent sensors, enabling real‐time measurement of drug concentrations. Encapsulated SWCNTs show a dose‐dependent fluorescence response across physiologically relevant concentrations and retain their fluorescence ...

Shadow‐Free Back‐Contact Perovskite Thin‐Film Detectors for Direct Extreme‐Ultraviolet and Soft X‐Ray Sensing

Advanced Materials Interfaces, EarlyView.
A triple‐cation perovskite detector with a quasi‐interdigitated back‐contact architecture enables highly sensitive and linear EUV/soft x‐ray detection by minimizing electrode shadowing and enhancing charge extraction. Efficient interfacial carrier collection and rapid temporal response highlight the potential of back‐contact‐engineered perovskites for ...

Enhancing Performance and Reliability of Hf1‐xZrxO2 Morphotropic Phase Boundary Films via Nanolaminate Structuring and Microwave Annealing

Advanced Materials Technologies, EarlyView.
Hf–Zr–O‐based morphotropic phase boundary (MPB) thin films often suffer from limited endurance and poor uniformity due to intrinsic phase instability. This work proposes a nanolaminate architecture that spatially separates competing phases, stabilizes phase formation, and suppresses wake‐up‐induced degradation.
