Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

Advanced Materials, EarlyView.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Surface‐Ligand‐Dependent Excited‐State Dynamics in Aqueous CuInSe2/ZnS Quantum Dot–Chlorophyll Assemblies

Advanced Materials Interfaces, EarlyView.
CuInSe2/ZnS quantum dots are synthesized in water and coupled with chlorophyll to probe ligand‐controlled excited‐state interactions. Broad visible–NIR emission and high PLQY are observed. Time‐resolved measurements reveal shortened chlorophyll lifetimes, indicating dynamic quenching via Förster energy and/or charge transfer, highlighting surface ...
