Title:
Dynamic Electrical Switching of DNA Layers on a Metal Surface 
Abstract:
We report on the dynamic control over the orientation of short oligonucleotide strands which are tethered to gold surfaces in electrolyte solution. By applying alternating electrical bias potentials to the supporting electrodes we are able to induce a switching of the layer conformation between a “lying” and a “standing” state, simultaneously monitored in a contactless mode by fluorescence techniques. We demonstrate that our electrooptical experiments allow for an in-depth investigation of the i...    »
