Single-photon upconversion [PDF]

arXiv, 2017
The phenomenon of upconversion, in which a system sequentially absorbs two or more photons and emits a photon of a higher frequency, has been used in numerous applications. These include high-resolution non-destructive bioimaging, deep-penetrating photodynamic therapy, and photovoltaic devices.

A Tailored Hydrogel With Local Glycemia Management, Antioxidant Activity, and Photothermal Antibacterial Properties for Diabetic Wound Healing

Advanced Science, EarlyView.
A multifunctional wound dressing (ACG gels) with antioxidant, local glycocontrol, and antibacterial properties to promote diabetic wound healing. Au‐CeO2 dumbbells effectively eliminate ROS, protecting cells from oxidative stress‐induced damage while exhibiting significant near‐infrared photothermal antibacterial activity.

Structurally Defined Water‐Soluble Metallofullerene Derivatives towards Biomedical Applications

Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
A modular metallobuckytrio (MBT) platform provides a family of structurally defined, water‐soluble metallofullerene derivatives that can safely carry rare‐earth elements in tailorable molecules, showing promise in biomedicines including MRI contrast agents and photosensitizers. Abstract Endohedral metallofullerenes (EMFs) are excellent carriers of rare‐

Simultaneous Reversal of T Lymphocytes and Cancer Cells Metabolism Via a Biomimetic Heavy‐Atom‐Free Photosensitizers‐Based Combination Therapies to Boost Cancer Photoimmunotherapy

Advanced Science, EarlyView.
This work develops a cyanine dye named Cy‐BF and encapsulates it with phospholipids and platelet exosome vesicles to create CHL. Characterized by high phototoxicity, low dark toxicity, and enhanced tumor targeting, CHL demonstrates aggregation‐induced broadening of absorption spectra and NIR‐activated photothermal therapy and type I photodynamic ...
