Genetically encoded NAD and NADP sensors will revolutionize the study of redox biology. Biochemical analytical methods do not capture the transient intracellular redox changes associated with ...

In this paper, we report a new graphene-semiconductor hybrid phototransistor in which the internal photoemission signal is locally amplified within the graphene transistor itself. Importantly, we show ...

There is a growing body of evidence that iron in the brain may play a role in Alzheimer's disease. Lending weight to that idea, a new imaging probe has for the first time shown that in the same ...
