Zusammenfassung:A composition having one or more nanoneedles is provided, where each nanoneedle has a silver tip and one or more of the silver tips comprise an AgCl layer. In one approach, one or more of the silver tips further include a layer of thiol-polyethylene glycol. A method of resistive pulse detection involving a protein pore is also provided. The method involves reconstituting one or more protein pores in a lipid membrane formed on the tip of a nanoneedle, then applying a potential across the membrane and detecting resistive pulses.
