    摘要: A sensor for sensing in a gas stream a vapor of a liquid. The sensor includes a micropore and a wet temperature sensor. The micropore has an evaporation end and has a lumen to conduct liquid from a supply of the liquid for evaporation at the evaporation end. The wet temperature sensor has a heat sensitive part in contact with the liquid in the micropore. The heat sensitive part circumscribes the micropore and forms part of the lumen. Heat loss due to evaporation of the liquid when the wet temperature sensor wet with the liquid is placed in the gas stream will result in the temperature sensed by the wet temperature sensor being lower than the non-evaporative temperature of the gas stream. This lowering in temperature can be measured to determine the concentration of the vapor in the gas stream. An example of such a sensor has a thermocouple junction having micropores passing through the thermocouple junction.

    摘要: A sensor and method for making a sensor includes providing a substrate having an adhesion layer with a first functional group operatively associated with a sol-gel composition having a second functional group, and at least one linker material for connecting the first functional group to the second functional group. In another embodiment, a sensor and method for making the sensor includes providing a sol-gel layer operatively associated with a sol-gel precursor solution that includes at least one co-polymer and at least one solvent adapted to resist the deformation of the sol-gel layer by decreasing evaporation, decreasing cross-linking, increasing intermolecular forces, or increasing elasticity.

    摘要: The invention provides an apparatus and method for detection of a target molecule. The apparatus includes a probe labeled with a transition metal-ligand complex that hybridizes with the target to form an initial complex, a metal ion for doping the initial complex and forming a final complex, and a potential means for providing a potential to the final complex to produce a detectable signal indicating the presence of the target after redox reaction. The method of the invention teaches the steps of hybridizing a probe with an attached label to the target to produce an initial complex, adding a metal ion to the initial complex to form a final complex and applying a potential to the final complex to produce a measurable signal.
