Organic AIE Nanoradiosensitizer Potentiates X‐Ray Triggered Continuous Reactive Oxygen Species Generation for Potent Cancer Radioimmunotherapy

open access: yesAdvanced Materials, EarlyView.
Herein, a glutathione‐responsive system (named THN) is prepared for X‐ray‐triggered sustained ROS generation for efficient antitumor immunotherapy. The double‐promoting ROS generation of THN induced massive immunogenic cancer cell death and polarized M2 macrophages into the M1 phenotype for enhanced antitumor immunotherapy.

TeV gamma-ray sources

AIP Conference Proceedings, 2001
Several TeV sources γ-rays have been detected in the past decade, and others have been proposed. They can be divided into three main categories: galactic, extra-galactic, and exotic. Here I review the two former categories, which contain the sources which have been observed, with discussions of the source characteristics and the physical mechanisms by ...

A New Source of Gamma Rays

Science, 2000
Relativistic outflows or "jets" are collimated streams of high-energy electrons that emit synchrotron radiation at radio wavelengths and have bulk velocities that are a substantial fraction of the speed of light. They trace the outflow of enormous amounts of energy and matter from a central supermassive black hole in distant radio galaxies.

Galactic Gamma-Ray Sources

Annual Review of Astronomy and Astrophysics, 1983
In Volume 5 of the Annual Review of Astronomy and Astrophysics (1967) Giovanni Fazio (76a) wrote that "... up until now, no photons of energy greater than 100 keV originating from beyond the solar system have definitely been detected." Fourteen years later, gamma-ray astronomy is an accepted branch of observational astrophysics, with something like 105
