Drug-free nanoparticles halted aggressive breast cancer tumors in preclinical trial

New nanoparticles developed at the Technion do not release a drug, but rather affect the immune system around the tumor. In a preclinical trial, they inhibited aggressive triple-negative breast cancer.
Two-dimensional materials are considered one of the most promising directions for improving computer chips, but researchers at the Vienna University of Technology have found that some of them are unsuitable due to an underestimated physical effect.

Two birds with one stone - turning carbon dioxide into carbon nanofibers

The idea of ​​capturing carbon dioxide or converting it to other substances in order to combat climate change is not new. However, simply storing carbon dioxide in a certain compound may lead to its leakage into the environment
Caption: Above, azobenzene is a molecule that can change its shape with light. An azobenzene molecule switches between two forms under the influence of light. In the lower figure: a molecular cage containing the molecules of the photosensitizer azobenzene. The new mechanism is based on a supramolecular approach in which the molecules of azobenzene and the photosensitizer are locked together in a molecular cage. The limited space accessible to the caged molecules allows only the E-form, but not the Z-form of azobenzene, so this molecule is pushed out of the cage. Credit: Jonathan R. Church
