Honors Thesis
This thesis studied the Guanylate Kinase (GK) enzyme, which catalyzes the reaction of ATP into ADP, using nano-rheological techniques. A unique experimental setup was created in order to observe the conformational dynamics of the biological macromolecules. An oscillatory force was applied by attaching enzymes to a gold-coated surface and gold nanoparticles. An additional gold-coated surface was placed on top of the setup in order to create a parallel plate capacitor configuration. An oscillatory voltage was then applied across the capacitor to drive the gold nanoparticles and exert a force on the enzymes. The setup detected the ensemble averaged movement of …
