Abstract: Embodiments profile cannabinoids using a nanopore detector. Embodiments use an applied potential to electrophoretically draw a nanopore blockade reporter molecule into a nanopore channel to establish an electrophoretic molecular channel-capture for the reporter molecule. The reporter molecule includes one of an aptamer or a monoclonal antibody and has a specific binding to at least one of: a specific cannabinoid, a particular cannabinoid isoform; or a specific cannabinoid family. Embodiments receive a blockade channel current signal in response to a nanoscale membrane channel of the nanopore detector being partially blockaded by a presence of the reporter molecule non-covalently bonded to the membrane channel. Embodiments receive a blockade signal for the reporter molecule that is toggling between more than one level.

Abstract: Analytical tools and methods employing processing of channel current blockade measurements to detect or assess changes in environmental conditions generally, and more specifically, to detect and assess interactions between a blockade-producing auxiliary molecule in the channel and either the surrounding conductive medium generally or molecules in that conductive medium. The auxiliary molecule is disposed within the channel in order to generate a highly structured channel current blockade signal. The blockade signal resulting from inducing ionic current flow through the channel with auxiliary molecule present, is based on an auxiliary molecule chosen to be highly susceptible to modulation when the auxiliary molecule interacts with other molecules in the surrounding conductive medium, or when it otherwise is modified or affected at the molecular level by changes in the physical or chemical conditions of that surrounding medium.

Abstract: A skin incision device has a casing having a bottom surface with a slot formed therein, a cover positioned on the casing and slidable in a direction toward the bottom surface, a blade positioned in the casing adjacent the slot, an actuator cooperatively positioned between the cover and an interior of the casing, and a carriage element. The actuator engages the blade by its horizontal displacement triggered by the slidable movement of the cover toward the bottom surface of the casing. The carriage element guides the movement of the blade between a pre-actuated position and a post-actuated position. The blade moves outwardly through the slot, cuts with a horizontal movement, and returns inwardly through the slot.

Abstract: Methods and devices are provided for characterizing a duplex nucleic acid, e.g., a duplex DNA molecule. In the subject methods, a fluid conducting medium that includes a duplex nucleic acid molecule is contacted with a nanopore under the influence of an applied electric field and the resulting changes in current through the nanopore caused by the duplex nucleic acid molecule are monitored. The observed changes in current through the nanopore are then employed as a set of data values to characterize the duplex nucleic acid, where the set of data values may be employed in raw form or manipulated, e.g., into a current blockade profile. Also provided are nanopore devices for practicing the subject methods, where the subject nanopore devices are characterized by the presence of an algorithm which directs a processing means to employ monitored changes in current through a nanopore to characterize a duplex nucleic acid molecule responsible for the current changes.
