A sensor includes a resonant transducer, the resonant transducer being configured to determine the composition of an emulsion or other dispersion. The resonant transducer has a sampling cell, a bottom winding disposed around the sampling cell, and a top winding disposed around the bottom winding. The composition of the dispersion is determined by measuring the complex impedance spectrum values of the mixture of the dispersion and applying multivariate data analysis to the values.

Methods and sensors for selective fluid sensing are provided. A sensor includes a resonant inductor-capacitor-resistor (LCR) circuit and a sensing material disposed over the LCR circuit. The sensing material includes a coordination compound of a ligand and a metal nanoparticle. The coordination compound has the formula: (X)-M, where X includes an alkylamine group having the formula (R&#x2014;NH), an alkylphosphine having the formula (R&#x2014;P), an alkylphosphine oxide having the formula (RP&#x2550;O), an alkyldithiocarbamate having the formula (RNCS), an alkylxanthate having the formula (ROCS), or any combination thereof, R includes an alkyl group, n is 1, 2, or 3, and M includes the metal nanoparticle of gold, silver, platinum, palladium, alloys thereof, highly conductive metal nanoparticles, or any combination thereof. The sensing material is configured to allow selective detection of at least six different analyte fluids from an analyzed fluid mixture.

Highly selective chemical and biological sensors

A sensor includes a resonant transducer, the resonant transducer being configured to determine the composition of an emulsion. The composition of the emulsion is determined by measuring the complex impedance spectrum values of the mixture of the emulsion and applying multivariate data analysis to the values.

Methods and sensors for selective fluid sensing are provided. Each sensor includes a resonant inductor-capacitor-resistor (LCR) sensor that is coated with a sensing material. In order to collect data, an impedance spectrum is acquired over a relatively narrow frequency range, such as the resonant frequency range of the LCR circuit. A multivariate signature may be calculated from the acquired spectrum to discern the presence of certain fluids and/or fluid mixtures. The presence of fluids is detected by measuring the changes in dielectric, dimensional, resistance, charge transfer, and other changes in the properties of the materials employed by observing the changes in the resonant electronic properties of the circuit. By using a mathematical procedure, such as principal components analysis (PCA) and others, multiple fluids and mixtures can be detected in the presence of one another, even in a high humidity environment or an environment wherein one or more fluids has a substantially higher concentration (e.g. 10&#xd7;, 1,000,000&#xd7;) compared to other components in the mixture.

A sensing system includes an inductor-capacitor-resistor (LCR) resonator sensor having a substrate, a plurality of first sensing elements mutually spaced apart and disposed on the substrate, and a sensing material film being disposed on a first sensing region of the corresponding first sensing element.

Further, the system includes at least one sensor disposed proximate to the sampling assembly. The sensor is configured to determine at least one property of the test fluid. The system also includes a housing that is disposed around the sampling assembly. The housing defines a fluid chamber that houses a balancing fluid. Furthermore, the system includes a flexible device disposed in the fluid chamber that draws a second portion of the test fluid. The flexible device is configured to balance pressure exerted by the test fluid on the sampling assembly by exerting pressure on the balancing fluid with the second portion of the test fluid.
