The ability to image in high resolution live tissue is critical for future biomedical and biophysics technologies. Based on biomimiquery approaches, PEAQS researchers are developing and characterizing sample platforms that would emulate biological structural and mechanical properties of alveolar-capillary interface of human lungs to grow and study live lung cells. Developing layered nanosensor arrays for brain functional imaging (Leads: Yoon, Murnane) Imaging of fast electrical network activity in the nervous system is a major goal in current neuroscience. Fast electrical impedance tomography (f-EIT) is 2D and 3D imaging of brain function with high temporal resolutions. PEAQS researchers are developing, fabricating, and characterizing novel arrays of layered nanoscale probes to measure fast brain activity with high-throughput.
