    摘要: The present invention relates to a biosensor. The biosensor includes a support substrate, electrodes positioned on the support substrate, a spacer substrate positioned on the support substrate, and a cover positioned on the spacer substrate. The cover cooperates with the support substrate to define a capillary channel. The electrodes include at least one working electrode defining a working electrode area in the capillary channel. The working electrode is configured to minimize variation in the working electrode area in the capillary channel due to variations in the spacer substrate placement relative to the working electrode.

    摘要: A biosensor having multiple electrical functionalities located both within and outside of the measurement zone in which a fluid sample is interrogated. Incredibly small and complex electrical patterns with high quality edges provide electrical functionalities in the biosensor and also provide the electrical wiring for the various other electrical devices provided in the inventive biosensor. In addition to a measurement zone with multiple and various electrical functionalities, biosensors of the present invention may be provided with a user interface zone, a digital device zone and/or a power generation zone. The inventive biosensors offer improved ease of use and performance, and decrease the computational burden and associated cost of the instruments that read the biosensors by adding accurate yet cost-effective functionalities to the biosensors themselves.

    摘要: Electrode arrangements for test elements, test elements and methods of determining sample sufficiency, monitoring fill time, establishing fill directions and/or confirming electrode coverage by a sample for test elements are disclosed. The test elements have an electrode-support substrate including a spacer having an edge defining a boundary of a capillary channel. The electrode-support substrate also includes a first electrode pair and a second electrode pair, wherein the first electrode pair is positioned between the second electrode pair. The method includes dosing the test sensor with the fluid sample; applying a signal to the first electrode pair and the second electrode pair, detecting a first response to the signal from the first electrode pair, and detecting a second response to the signal from the second electrode pair; determining a time period between the first response and the second response and then applying a measurement test sequence for an analyte of interest on the fluid sample if the time period is less than a first predetermined threshold.

    摘要: The invention provides methods and systems for separating particles that exhibit different Raman characteristics. The method can include introducing nanoparticles, on which Raman-active molecules are adsorbed, into a photopolymerizable resin and exposing to excite Raman active vibrational modes of the molecules to generate Raman-shifted radiation suitable for polymerizing the resin such that the Raman-shifted radiation causes selective polymerization of a resin surrounding nanoparticles if the nanoparticles provide a Raman enhancement factor greater than a threshold. In addition, methods for electrically isolating nanoparticles, or selectively removing one type of nanoparticles from collections, are disclosed. These methods rely on generation of blue-shifted anti-Stokes photons to selectively expose portions of a photoresist covering the nanoparticles to those photons. Such exposure can cause a change in the exposed portions (e.g., polymerize or increase solubility to a developing agent), which can be employed to achieve isolation of the nanoparticles or their selective removal.

    摘要: In one aspect, a system for use in product packaging is disclosed that includes a polymeric sensing substrate coupled to a package such that a front sensing surface thereof is in contact with a portion of a product, e.g., a fungible product, stored in the package and a back surface thereof is accessible via an environment external to the package. The system further includes a radiation source adapted to direct radiation to the substrate's back surface such that the radiation would interact with one or more molecular species of the product that are in contact with the substrate's sensing surface. The system also includes a detector that is adapted to detect radiation returning from the substrate in response to its illumination by the radiation source. The front surface of the sensing substrate can comprise a plurality of micron-sized or submicron-sized ridges having a discontinuous or continuous metal coating, e.g., a metallic layer with a thickness in a range of about 10 nm to about 1000 nm (and preferably in a range of about 50 nm to about 120 nm), disposed thereon.
