摘要： Systems and techniques for probing interfaces between electrodes and conductive solutions. In one aspect, devices can include a time variable source of power configured to output power that varies in time over a pair of output conductors, an electrode connected to a first of the conductors, an extrinsic inductive impedance connected between the pair of output conductors, and an impedance sensor connected to one or both of the output conductors and configured to measure net impedance between the pair of output conductors based on a known current or voltage output by the time variable power output. The measured net impedance includes the extrinsic inductive impedance and an impedance of the interface. The electrode is configured to be submersed in a conducting solution and form an interface with the conducting solution.

摘要： Oligonucleotide structures are provided that are capable of forming more stable bonds to a lipid membrane and thereby generate an improved control of the process whereby oliogonucleotide linkers are introduced to lipid membranes. Methods of forming lipid membrane oligonucleotide attachments are provided including lipid vesicles. The oligonucleotides typically comprise at least two hydrophobic anchoring moieties capable of being attached to a lipid membrane. Said moieties may be attached at the terminalends of an oligonucleotide or, in the case of a first and second strand forming a duplex, at the same terminal end one of the strands other end not being part of the duplex leaving it free to hybridize to additional strands. The lipid vesicles attached with the oligonucleotide can be used in biosensors and may contain membrane proteins.

摘要： The present invention provides a method for studying transport of an agent across a membrane comprising the steps a) providing at least one surface with a bilayer structure tethered to the surface, said bilayer structure comprising a detection volume, b) contacting the bilayer with at least one agent to be analysed, and c) detecting a change in refractive index in the detection volume resulting from transportation of the agent across the membrane. Further there is provided a device comprising a) at least one surface, b) at least one bilayer structure tethered to the surface, and c) at least one sensor capable of detecting a change in refractive index in a detection volume, wherein the bilayer structure encloses a first volume of the detection volume and wherein the volume not enclosed by the bilayer structure but within the detection volume is a second volume and wherein the ratio between the first volume and second volume is above about 0.001.
