Paving the Way to Elucidate Hg's Role in Tumorigenesis

open access: yesAdvanced Science, EarlyView.
Tumorigenesis can result from diverse environmental carcinogens. Among them, mercury—a lifelong bioaccumulative Group 2B carcinogen—has tumorigenic potential that remains poorly understood due to confounding co‐exposures and limited organ‐specific data.

Liposomal Nanoconfinement Enables Type I Photodynamic Conversion for Synergistic Cancer Photothermal‐Immunotherapy

open access: yesAdvanced Science, EarlyView.
Liposomal nanoconfinement converts the hemicyanine photosensitizer RhM from Type‐II to Type‐I photodynamic therapy (PDT) while enhancing photothermal therapy (PTT). The RhM‐R837@Lip nanoassembly efficiently generates superoxide (O2•−) and hydroxyl radicals (•OH) to kill tumor cells and achieve tumor ablation.

[Singlet oxygen therapy].

open access: yesKlinichna khirurhiia, 1997
Physico-chemical concept of the singlet oxygen therapy application using photochemically sensibilized air or drinking a water, already barbaturized by an activated singlet oxygen of air, is adduced. Therapy technology and examples of its clinical application in the treatment of several pathologic processes for the free-radicals correction are depicted.

Asymmetric Active Center Triggers Side‐On Photo‐Fenton‐Like Reaction Through Polar Charge Transfer and Self‐Adapting Sulfur Vacancies

open access: yesAdvanced Science, EarlyView.
The Cu‐Zn3In2S6 photocatalyst (Cu‐ZISV) with asymmetric Cu‐SV‐Zn sites was designed and synthesized to boost peroxymonosulfate (PMS) activation kinetics. The side‐on photo‐Fenton‐like reaction by the asymmetric Cu‐SV‐Zn site accelerated PMS activation and pollutant degradation, and the first‐order kinetic constant of Cu‐ZISV increased by 4.87 times ...

Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering

open access: yesAdvanced Science, EarlyView.
This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.

Multi‐Level Confinement Single‐Molecule Charge Transfer Activated PRET for Near‐Infrared Targeted Cell Imaging

open access: yesAdvanced Science, EarlyView.
The cascade supramolecular assembly of charge‐transfer arrays not only triggered a topological transformation from nanofiber to nanorod and vesicles, but also promoted single‐molecule phosphorescent resonance energy transfer, expanding phosphorescence emission at 500 nm to near‐infrared delayed fluorescence emission at 650 nm with a lifetime of 11.20 ...

Aptamer‐Engineered Liposomal Platform Enables in Situ cDC1 Vaccination to Potentiate Immunotherapy in Prostate Cancer

open access: yesAdvanced Science, EarlyView.
Prostate cancer is immunologically ‘cold’, with scarce, dysfunctional type 1 conventional dendritic cells (cDC1s) that limit T cell priming. We introduce an aptamer‐targeted liposomedelivering FMS‐like tyrosine kinase 3 ligand (Flt3L) and chlorin e6 (Ce6). Ultrasound induces antigen release and cDC1s recruitment, creating an in situ cDC1 vaccine.

A Reliable Strategy to Unravel the Structure and Composition of Semiconducting Conjugated Donor‐Acceptor Block Copolymers

open access: yesAdvanced Science, EarlyView.
This work proposes a reliable strategy to elucidate the structure and composition of conjugated donor‐acceptor block copolymers. The method, based on NMR analysis, allows to extract key structural information such as the number of heterojunctions (NoH) and the number of blocks (NoB) of the copolymers.

Surface‐Bound Superoxide Radical‐Mediated Photo‐Fenton Mineralization of Ciprofloxacin on Fe‐Sillenite Nanosheets

open access: yesAdvanced Science, EarlyView.
This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.
