Ferritin is an iron-storage protein that exists in large quantities in bacteria, plants, and the blood of many mammals, including humans. (1−3) This intracellular protein naturally stores iron and releases it in a controlled fashion. Ferritin plays a key role in preventing diseases and in the detoxification of metals in living organisms.
Web22 de jun. de 2024 · Vacuum birefringence (VB) is a basic phenomenon predicted in quantum electrodynamics (QED). However, due to the smallness of the signal, conventional magnet-based and extremely intense laser-driven detection methods are still very challenging.
