  • Patent number: 11965883
    Abstract: Provided are point of care sensor systems that include portable readers and disposable cartridges for receiving and analyzing samples. A cartridge may be equipped with one or more sensor channels, each containing one or more sensors. After providing a sample to a cartridge, the cartridge can be inserted into a reader, which can interact with the cartridge to perform on-cartridge sensing and receive signals indicating the presence and/or quantity of one or more targets in the sample. Examples of cartridges can include cardiac panels, sepsis panels and the like. In some embodiments, the same sensor hardware may be configured for multiple measurements of different targets conducted at different time frames. Also provided herein are novel on-cartridge solid and liquid reagent storage and delivery mechanisms.

  • Patent number: 11055218
    Abstract: An apparatus for accelerating tasks during storage caching and tiering includes a processor. First and second storage units are coupled to the processor. A memory unit is coupled to the processor. The memory unit is configured to receive a write data operation. An amount of dirty data in the first storage unit is determined based on the received write data operation. The dirty data includes data present in the first storage unit to be synced to the second storage unit. A sync rate associated with a read data operation from the first storage unit to the second storage unit is decelerated when the amount of dirty data is less than a first threshold value. A write rate associated with a write data operation to the first storage unit is accelerated when the amount of dirty data is less than the first threshold value.

  • Patent number: 9357946
    Abstract: The present invention provides a direct sampler and detector for analytes found in exhaled breath condensate. Analytes in the breath condensate are detected instantaneously as they condense prior to reaching the sensor surface or condense directly on the sensor surface. Because the analysis or assay is performed immediately after patient exhalation, analyte stability is significantly improved providing accurate, reliable, consistent, and clinically applicable results. In certain embodiments, combined breath condensate/breath samplers and detectors are provided, enabling multiplexed analysis of condensed and vapor-phase analytes provided in a single sampling session. Breath is collected and directed to one or more subsystems. Within each subsystem, the breath portion is either condensed or prevented from condensing.

  • Patent number: 8993346
    Abstract: Provided herein is a new hybrid material system, mCNT, including magnetic carbon nanotubes for biological and medical sensing applications. In certain embodiments, the systems include magnetic material on the interior of carbon nanotubes (CNTs). The amount of magnetic particles inside CNTs may be such that mCNT can respond to small, low cost, portable magnet. The exterior CNT surface is kept intact for biomolecular attachments or other functionalizations. Performance enhancement with this novel material includes improved sensitivity, reduced response time, and reduced sample volume. According to various embodiments, the mCNTs are substrates for the adherence of molecules participating in these assays or as active sensing elements. Also provided are methods of fabricating two-dimensional mCNT and CNT networks on printed electrodes.
