  • Publication number: 20150056364
    Abstract: Techniques for assembling a lipid bilayer on a substantially planar solid surface are described herein. In one example, a lipid material such as a lipid suspension is deposited on a substantially planar solid surface, a bubble filled with fast diffusing gas molecules is formed on the solid surface, and the gas molecules are allowed to diffuse out of the bubble to form a lipid bilayer on the solid surface.

  • Publication number: 20140374252
    Abstract: 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.

  • Publication number: 20140374253
    Abstract: Techniques for manipulating a molecule in a nanopore embedded in a lipid bilayer are described. In one example, an acquiring electrical stimulus level is applied across a lipid bilayer wherein a region of the lipid bilayer containing the nanopore is characterized by a resistance and wherein the acquiring electrical stimulus level tends to draw the molecule from a surrounding fluid into the nanopore, a change in the resistance of the lipid bilayer resulting from the acquisition of at least a portion of a molecule into the nanopore is detected, the acquiring electrical stimulus level is changed to a holding electrical stimulus level wherein the portion of the molecule remains in the nanopore upon the changing of the acquiring electrical stimulus level to the holding electrical stimulus level.

  • Publication number: 20140203464
    Abstract: 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.

  • Publication number: 20110287414
    Abstract: Techniques for identifying a portion of a molecule are described herein. In one example, multiple electrical measurements associated with a molecule are acquired, wherein each of the multiple electrical measurements corresponds to a discrete position of the molecule within a nanopore. The multiple electrical measurements are correlated with one or more sequences of electrical measurements corresponding to a possible structure of the molecule. The portion of molecule is determined to include the possible structure of the molecule based on the correlation.

  • Patent number: 5518126
    Abstract: A plasticware retainer is provided for holding lightweight articles in a dishwasher rack to prevent them from dislodging during a washing cycle. The retainer includes a net member, a roller assembly, and connectors. A first end of the net member is attached to the roller assembly which removably attaches to the dishwasher rack. The connectors are attached to a second end of the net member to attach the second end of the net member to the rack when the net member is in an extended position over the dishwasher rack to prevent the lightweight articles from dislodging during washing. The net member is retracted into the roller assembly in a window shade fashion to remove the articles in the dishwasher rack and or storage of the plasticware retainer.
