  • Publication number: 20220401960
    Abstract: A radiosynthesis system is disclosed that leverages droplet microfluidic radiosynthesis and its inherent advantages including reduction of reagent consumption and the ability to achieve high molar activity even when using low starting radioactivity. The radiosynthesis system enables the parallel synthesis of radiolabeled compounds using droplet-sized reaction volumes. In some embodiments, a single heater is used to create multiple reaction or synthesis sites. In other embodiments, separate heaters are used to create independently-controlled heating conditions at the multiple reaction or synthesis sites. In one embodiment, a four-heater setup was developed that utilizes a multi-reaction microfluidic chip and was assessed for the suitability with high-throughput radiosynthesis optimization. Replicates of several radiochemical operations including the full synthesis of various PET tracers revealed the platform to have high repeatability (e.g., consistent fluorination efficiency).

  • Publication number: 20220251025
    Abstract: A chemical synthesis platform based on a particularly simple chip is described herein, where reactions take place atop a hydrophobic substrate patterned with a circular hydrophilic liquid trap. The overall supporting hardware (heater, rotating carousel of reagent dispensers, etc.) can be packaged into a very compact format (about the size of a coffee cup). We demonstrate the consistent synthesis of [18F]fallypride with high yield, and show that protocols optimized using a high-throughput optimization platform we have developed can be readily translated to this device with no changes or reoptimization.

  • Publication number: 20220244228
    Abstract: A method of performing high-throughput radio thin layer chromatography (radio-TLC) includes spotting a plurality of locations on one or more TLC plates with samples containing a radiochemical or a radiopharmaceutical, each location defining an individual lane on the one or more TLC plates for the respective samples. The one or more TLC plates are developed with a developing solution and dried. The TLC plates are imaged with an imaging device comprising a camera, wherein the image obtained from the camera comprises a field of view that contains regions of interest (ROIs) from the plurality of lanes. The ROIs in the images obtained from the camera may then be analyzed by the user. The ROIs may be used, for example, reaction optimization or for quality control check of the production of radiotracers.

  • Patent number: 11398311
    Abstract: The invention relates to a method and a system for providing a representation of synchronicity of electrical activation of heart tissue. The method includes obtaining a three-dimensional model of electrical activation of the heart. The three-dimensional model includes a mesh with a plurality of nodes, each node having associated therewith a time delay between stimulation of the heart at a stimulation site and activation of the heart at that respective node. For each node a stimulus site is defined at the location of that node. For each node a modified three-dimensional model of electrical activation of the heart resulting from stimulation at that node is determined. For each node a measure for heart activation synchronicity for the heart based on stimulation at that node is determined A heart synchronicity map is determined representing a three-dimensional model of the heart, indicating at each node the respective measure for heart activation synchronicity.

  • Patent number: 11209390
    Abstract: A volumetric microfluidic injector for capillary electrophoresis (CE) for highly repeatable sample injection has been designed and built to eliminate known injection bias in hydrodynamic injection. A defined volume from 1-10 nL or 0.1-100 nL of sample is confined in a defined region of a micro-valve PDMS microfluidic injector chip and electrophoretic potential is applied to drive sample into a separation device such as an embedded fused silica capillary for separation and detection. Using a 75 ?m ID capillary, the RSD of an absorbance peak area as low as 1.32% (n=11) is obtained. As a comparison, the time-dependent injection was tested using the same chip which resulted in an inferior repeatability.
