DNA attached to nanoparticles found to contribute to lupus symptoms

Physorg.com - 21 марта, 2024 - 19:24
Autoimmune diseases are mysterious. It wasn't until the 1950s that scientists realized that the immune system could harm the organs of its own body. Even today, the fundamental causes and inner workings of most autoimmune diseases remain poorly understood, limiting the treatment options for many of these conditions.

New method for analyzing nanoporous materials

Physorg.com - 21 марта, 2024 - 17:02
In addition to their main components, the properties of crystalline and nanoporous materials often depend crucially on guest atoms or ions that are embedded in the tiny pores of their lattice structure. This applies to high-tech materials used in sensor or separation technology as well as to natural materials. The bluish gemstone aquamarine, for example, would be colorless without such guest components.

Cleaning up environmental contaminants with quantum dot technology

Physorg.com - 20 марта, 2024 - 12:00
The 2023 Nobel Prize in Chemistry was focused on quantum dots—objects so tiny, they're controlled by the strange and complex rules of quantum physics. Many quantum dots used in electronics are made from toxic substances, but their nontoxic counterparts are now being developed and explored for uses in medicine and in the environment. One team of researchers is focusing on carbon- and sulfur-based quantum dots, using them to create safer invisible inks and to help decontaminate water supplies.
