摘要： A method of making a nanostructured palladium thin film electrode is described. The method involves contacting a substrate with an aerosol comprising a solvent and a Pd(II) compound. The substrate is heated, and no hydrogen gas or an additional reducing agent is required to reduce the Pd(II) to form the deposited thin film. The nanostructured palladium thin film electrode is capable of detecting compounds such as hydrazine in an aqueous sample with a 10 nM limit of detection.

摘要： A method of distinguishing a control solution from a sample in an electrochemical test sensor is performed. The method includes adding a control marker to the control solution. The control solution includes the control marker and analyte. The test sensor includes working and counter electrodes, and a reagent. A potential is applied to the test sensor to oxidize the control marker and the analyte. The resulting electrical current is measured. A potential is applied to the test sensor lower than the other potential in which the potential is sufficient to oxidize the analyte and not the control marker. The resulting electrical current is measured. Determining whether a control solution or a sample is present based on the measured electrical currents. To increase the measured current, a salt may be added to the control solution in an amount sufficient to increase the electrical current by at least 5% as compared to a control solution in the absence of a salt.

摘要： A number of variations may involve a method that may include providing a non-conductive layer. A conductive layer may be provided overlying the non-conductive layer with the conductive layer to form a sensor device. An opposition to electrical current through the conductive layer may be monitored. The location of a status of the non-conductive layer or of the conductive layer may be determined through a change in the opposition.

摘要： A method for determining a salt concentration of a hydrocarbon fluid using a conductivity sensor and a hydrocarbon testing solution includes forming the hydrocarbon testing solution. The electropolymerizable monomer is operable to form a resultant associated polymer at a peak potential of the electropolymerizable polymer. The method includes introducing the hydrocarbon testing solution into the conductivity sensor. The method includes inducing a range of potential across the hydrocarbon testing solution such that at least a portion of the electropolymerizable monomer polymerizes. The range of induced potential includes the peak potential of the electropolymerizable polymer. The method includes detecting a range of electrical current associated with the range of potential induced. The method also includes the step of determining the salt concentration of the hydrocarbon fluid using the range of potential induced and the range of electrical current detected.

摘要： A method of measuring a quantity of a substrate contained in sample liquid is provided. This method can reduce measurement errors caused by a biosensor. The biosensor includes at least a pair of electrodes on an insulating beard and is inserted into a measuring device which includes a supporting section for supporting detachably the biosensor, plural connecting terminals to be coupled to the respective electrodes, and a driving power supply which applies a voltage to the respective electrodes via the connecting terminals. One of the electrodes of the biosensor is connected to the first and second connecting terminals of the measuring device only when the biosensor is inserted into the measuring device in a given direction, and has a structure such that the electrode becomes conductive between the first and second connecting terminals due to a voltage application by the driving power supply.

摘要： In one aspect, a method for detection of a target in a sample based on the change of electrochemical cyclic voltammetry peak profile is provided. The method may involve at least two or more electroactive moieties (EAMs) comprising a transitional metal complex and an anchor group. Said transitional metal complex may be capable of reversibly or semi-reversibly transferring one or more electrons. Said anchor group may allow said EAMs to covalently attach to a solid support, forming a self-assembled monolayer (SAM) on the surface. At least one EAM may further comprises a capture ligand that can be recognized and bound by a target or a surrogate target. When a sample is introduced to an EAM, the interaction between said capture ligand and said target or surrogate target may lead to change of the properties of the SAM containing all EAMs involved. Said change can be detected by an electrochemical detection system.
