For the first time: "smart liquids" will be used as sensitive biological sensors

The team of researchers explained that the uniqueness of the smart liquids is that, as a result of their chemical properties, the liquids maintain separation from each other, thus creating distinct droplets

The interaction between the proteasome and NQO1 is based on mutual inhibition: the proteasome breaks down unstructured NQO1 enzymes (which are not bound to FAD), while the enzyme, when bound to FAD, prevents the proteasome from breaking down other proteins - including itself
