Understanding/unravelling carotenoid excited singlet states. [PDF]

, 2018
Carotenoids are essential light-harvesting pigments in natural photosynthesis. They absorb in the blue–green region of the solar spectrum and transfer the absorbed energy to (bacterio-)chlorophylls, and thus expand the wavelength range of light that is ...

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 ...
