Spatially-controlled immobilization of polyplexesSuzie H. Pun, University of Washington, DMR 0706647 Overall Goal: Developing a system for spatially and temporally controlled delivery of polyplexes (polymer/nucleic acid complexes used for delivery). Top Figure: Spatial Delivery is achieved by specific immobilization of hexahistidine-tagged nanoparticles on Ni-NTA functionalized SAMs. Bottom Figure: Surface plasmon resonance demonstrates that immobilization is specific and requires both the hexahistidine tag on the particles and the Ni-NTA on the surface Temporal delivery is achieved because cellular uptake requires releasing agents imidazole and EDTA .

Our efforts were recently highlighted by Amgen Scholars. (Left) The Pun Laboratory presents for University of Washington’s Math Academy, a program that supports ~30 high school juniors from underrepresented minority backgrounds in a 4-week residential session at UW. The Pun lab prepared lectures and several hands on demonstrations.
