Patterning Bioactive Proteins or Peptides on Hydrogel Using Photochemistry for Biological Applications Taylor B. Dorsey1,2,3, Alexander Grath1,2, Cancan Xu4, Yi Hong4, Guohao Dai1,2,3 1Department of Biomedical Engineering, Rensselaer Polytechnic Institute, 2Center for Biotechnology and Interdisciplinary Studies, Rensselaer Polytechnic Institute, 3Department of Bioengineering, Northeastern University, 4Department of Bioengineering, University of Texas at Arlington In this method, we use photopolymerization and click chemistry techniques to create protein or peptide patterns on the surface of polyethylene glycol (PEG) hydrogels, providing immobilized bioactive signals for the study of cellular responses in vitro.
Small and Wide Angle X-Ray Scattering Studies of Biological Macromolecules in Solution Li Liu1, Lauren Boldon1, Melissa Urquhart1, Xiangyu Wang1 1Department of Mechanical, Aerospace, and Nuclear Engineering, Rensselaer Polytechnic Institute The demonstration of the small and wide angle X-ray scattering (SWAXS) procedure has become instrumental in the study of biological macromolecules. Through the use of the instrumentation and procedures of specific angle methods and preparation, the experimental data from the SWAXS displays the atomic and nano-scale characterization of macromolecules.
Recording Human Electrocorticographic (ECoG) Signals for Neuroscientific Research and Real-time Functional Cortical Mapping N.

Eng., Rensselaer Polytechnic Institute, 6Department of Biomed. Sci., State University of New York at Albany, 7Department of Elec. and Comp. Eng., University of Texas at El Paso We present a method for collecting electrocorticographic signals for research purposes from humans who are undergoing invasive epilepsy monitoring. We show how to use the BCI2000 software platform for data collection, signal processing and stimulus presentation. Specifically, we demonstrate SIGFRIED, a BCI2000-based tool for real-time functional brain mapping.
