摘要: A method of forming a nanopore in a lipid bilayer is disclosed. A nanopore forming solution is deposited over a lipid bilayer. The nanopore forming solution has a concentration level and a corresponding activity level of pore molecules such that nanopores are substantially not formed un-stimulated in the lipid bilayer. Formation of a nanopore in the lipid bilayer is initiated by applying an agitation stimulus level to the lipid bilayer. In some embodiments, the concentration level and the corresponding activity level of pore molecules are at levels such that less than 30 percent of a plurality of available lipid bilayers have nanopores formed un-stimulated therein.

摘要: Techniques for forming a nanopore in a lipid bilayer are described herein. In one example, an agitation stimulus level such as an electrical agitation stimulus is applied to a lipid bilayer wherein the agitation stimulus level tends to facilitate the formation of nanopores in the lipid bilayer. In some embodiments, a change in an electrical property of the lipid bilayer resulting from the formation of the nanopore in the lipid bilayer is detected, and a nanopore has formed in the lipid bilayer is determined based on the detected change in the lipid bilayer electrical property.

摘要: Techniques for characterizing a molecule are described herein. In one example, a portion of the molecule is trapped in a nanopore, a variable voltage is applied across the nanopore until the trapped portion of molecule is moved within the nanopore, and the molecule is characterized based on the electrical stimulus required to affect movement of at least a portion of the trapped portion of the molecule within the nanopore.
