The Vanderbilt Institute for Integrative Biosystems Research and Education (VIIBRE) is developing nanophysiometers for measurements on single cells and nanobioreactors for perfusing small populations of cells in multiple cell traps and organs-on-chips. VIIBRE’s nanobioreactors are being interfaced to nanoelectrospray, ion mobility-mass spectrometers for real-time metabolomic analyses. The sensor and potentiostat technologies developed by the Cliffel and Wikswo collaboration are immediately applicable to the measurement of glucose, lactate, oxygen, and pH levels in cells in multitrap nanophysiometers and organs on chips, allowing the assessment of dynamic metabolic activity in response to specific challenges delivered in vitro. Optical sensing and imaging platforms developed by VIIBRE and its collaborators couple into the sub-nanoliter space for rapid customization of specific fluorescent and luminescent assays. The use of optical probes in combination with the nanophysiometer allows the integration of novel sensing mechanisms to monitor cell physiology and environmental toxicology. VIIBRE has contributed to the development of a system for time-resolved spectroscopic imaging of nanoparticles and nanoclusters, and for studying protein complexes in single cells.
