Aggregate, Volume 7, Issue 1, January 2026.We have successfully developed a hypoxia‐responsive near‐infrared phosphorescent probe, Ir‐PEG. This nanoprobe demonstrates high sensitivity, water solubility, and deep‐tissue penetration. It remains specifically activatable even in the hypoxic intestinal environment, facilitating high‐contrast imaging of orthotopic colon cancer.

Photo‐Autocatalysis: Insights From Light‐Driven Self‐Catalyzed Organic Transformations
Chemistry – An Asian Journal, Volume 21, Issue 2, 28 January 2026.This perspective highlights recent advancements in photo‐autocatalytic reactions—light‐driven processes characterized by self‐accelerating kinetics. We explore the underlying mechanisms, demonstrating how photo‐autocatalysis can be realized either through a single photo‐autocatalyst or through a combination of a photocatalyst and an autocatalyst, and ...
