Nanoprobe enables measurement of protein dynamics in living cells

A team of researchers from Massachusetts General Hospital (MGH) and the Rowland Institute at Harvard University have used a specialized nanoprobe developed by the Harvard/Rowland investigators to directly measure levels of key proteins within living, cultured cells. As described in the journal Nano Letters, the investigators used the device to track levels of the Alzheimer's-disease-associated proteins amyloid-beta (A-beta) and tau in neurons and other cells exposed to an anesthetic known to pro
