Amphiphilic Nanographene With Aggregation‐Induced Type‐I Photodynamic Properties

Aggregate, Volume 7, Issue 4, April 2026.
Aggregation effects on the photophysics of an amphiphilic nanographene, dibenzo[hi,st]ovalene (DBOV‐OTEG), are demonstrated, elucidating the rapid population of intermolecular charge‐transfer (CT) in water. The CT states mediate non‐radiative and electron transfer pathways, which enhance photothermal (PT) conversion and activate Type‐I photodynamic (PD)

Cutaneous photosensitivity of phototheranostic porphyrin–lipid nanoparticles

Photochemistry and Photobiology
Abstract Skin photosensitization is a common challenge following intravenous administration of many photodynamic therapy (PDT) drugs, typically lasting days, weeks, or months in laboratory animals and patients. Symptoms of photosensitivity manifest as erythema and edema on skin exposed to sunlight or bright artificial lighting. Recent

Bimetallic Peroxide Nanocomposites‐Driven Redox Dyshomeostasis to Activate Sequential Cuproptosis and Pyroptosis for Amplified Tumor Immunotherapy

Advanced Science, Volume 13, Issue 18, 27 March 2026.
Hyaluronic acid‐modified bimetallic peroxide nanocomposites (MgO2‐CuO2@HA) are designed for synergistic tumor therapy. The nanocomposites release Mg2+, H2O2, and Cu2+ in tumor cells, induce cuproptosis via Cu+‐mediated protein aggregation, and activate pyroptosis through caspase‐1/gasdermin D pathways for inducing immunogenic cell death, collectively ...
