Alloxazine derivatives as multifunctional agents for photodynamic therapy, cancer cell imaging, and cell proliferation inhibition

open access: yesPhotochemistry and Photobiology, EarlyView.
Alloxazine photosensitizers, molecularly engineered through sugar conjugation and methoxy substitution to enhance solubility, photodynamic potency, and fluorescence, enable image‐guided photodynamic therapy while inhibiting cancer cell growth in the absence of photoactivation.

An Organometallic [2]Catenane With Pt‒(di‐NHC)‒Pt Units: A Topology‐Driven Strategy for Enhanced Phosphorescence in Discrete Aggregates

open access: yesAngewandte Chemie, Volume 138, Issue 19, 4 May 2026.
The mechanically interlocked Borromean rings are stabilized by π···π stacking interactions while the [2]catenane is stabilized by solvophobic effects. While the π···π interactions in the Borromean rings lead to severe luminescence quenching, the solvophobically assembled [2]catenane effectively circumvents these interactions, simultaneously restricting

Zebrafish as a practical and convenient model for the study of photodynamic and photothermal therapy of solid tumors: A scoping review

open access: yesPhotochemistry and Photobiology, EarlyView.
Zebrafish provide a high‐throughput, optically transparent platform for cancer and drug screening. Their ~80% genetic homology, xenograft compatibility, and transgenic strains enable targeted photosensitizer screening, real‐time ROS and tumor imaging, and mechanistic assays, while fish embryo acute toxicity (FET) and in vitro tests streamline toxicity ...

Hydrogen Atom Transfer Induces Photodegradation in Carbonyl‐Based Multi‐Resonance TADF Emitters

open access: yesAngewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Boosting triplet harvesting in N/C═O MR‐TADF emitters unexpectedly induces rapid photodegradation under oxygen‐free conditions. Spectroscopic studies reveal that triplet excited states trigger hydrogen‐atom transfer from solvent to the carbonyl unit, driven by triplet energetics and hydrogen electrophilicity.

Leveraging Carbon Quantum Dots to Achieve UN Sustainable Development Goals in the Face of Climate Change

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
Carbon quantum dots (CQDs) play a significant role in supporting the UN SDGs by promoting the sustainable management of energy, healthcare, remediation, and agriculture in a multidisciplinary manner. It focuses on reducing waste, toxicity, and energy use while utilizing renewable resources.

Root and microbial contributions to anoxic microsite formation in the rhizosphere: a microfluidic approach

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3486-3498, June 2026.
Summary Plant root‐associated anoxic microsites may influence the fate of nutrients and contaminants in the rhizosphere, but their dynamics remain relatively unknown. To examine the formation of root‐induced anoxic microsites over space and time, we use microfluidic devices integrated with transparent, planar oxygen sensors in a wheat (Triticum ...
