The Biophysical Technology Center makes state-of-the-art instrumental resources for optical spectroscopy and EPR available to researchers, providing a venue for them to pursue their projects and develop their experience. Top priorities of the center personnel are to maintain the performance of these instruments at the highest level and to provide basic training to new users. In addition, the resident expertise in the center is available to facilitate spectroscopy efforts and contribute to the scientific research efforts of users in the development of strategies for data collection and analysis. The center is open as a first priority to all University of Minnesota researchers, and to outside researchers by arrangement.
