The Eunice Kennedy Shriver National Institute of Child Health and Human Development seeks research co-development partners and/or licensees to further develop and commercialize its methods of noninvasively and directly determining the absolute homeostatic state, metabolic activity, function, and viability of isolated cells, or tissues (ex vivo or in vivo), such as the Central Nervous System (CNS). The method uses Nuclear Magnetic Resonance or Magnetic Resonance Imaging measurements of the rate at which endogenous water exchanges across cell membranes.
