  • Methods and systems for preparing and preserving a biological sample
    Patent number: 11856945
    Abstract: Methods and systems for preparing and preserving biological samples are disclosed herein. A method comprises contacting a preserving agent with a biological sample to form a mixture, wherein the preserving agent is selected from at least one of a metal-organic framework (MOF) encapsulant or a precursor forming a MOF encapsulant, and wherein the biological sample comprises at least one target analyte. A system comprises a preserving agent selected from at least one of a metal-organic framework (MOF) encapsulant or a precursor forming a MOF encapsulant; and a substrate configured to receive a drop cast mixture of the preserving agent and a biological sample, wherein the biological sample comprises at least one target analyte.

  • Workflow assembly tool and workflow model
    Patent number: 11829575
    Abstract: Techniques for generating a workflow model are described. In an example, a device presents a window. A selection of an icon presented in the window is received, where the icon corresponds to a node having a node type. Based on rule, the device determines a location where the icon can be added to a workflow. The rule indicates the location based on the node type and a workflow model. The user device presents, in the window, an indicator of the location, receives a placement of the node at the location, and presents, the icon at the location indicating that the node is added to the workflow. The device updates the workflow model to include, based on the placement, a reference to executable code that corresponds to the node, and to include, based on the location, information about an execution sequence of executable codes referenced in the workflow model.
