  • Publication number: 20240302264
    Abstract: A method of analyzing shaped particles using a flow cytometer or a fluorescence activated cell sorter (FACS) includes flowing a population of shaped particles with at least some of the population of shaped particles having cells loaded therein through the flow cytometer or FACS and optically interrogating the shaped particles in the flow cytometer or FACS to measure scattered light for each shaped particle. A target shaped particle having a cell loaded therein is detected based at least in part on a measurement of forward scattered light, side scattered light, or back scattered light. The target shaped particle may also be identified with a measured fluorescence signal level. Sorting of target shaped particles may be optimized by adjusting one or more of a drop delay or a sorting mask configuration for the flow cytometer or FACS.

  • Publication number: 20210268465
    Abstract: Systems and methods are described herein that create discrete volumes associated with solid-phase particles (e.g., drop-carrier particles) suspended in an immiscible phase (e.g., dropicles). One embodiment of the system includes a plurality of hydrogel-based drop-carrier particles containing a microscale voids or cavities that hold an aqueous phase droplet of fluid within each drop-carrier particle. The plurality of hydrogel drop-carrier particles associated with aqueous drops are suspended as individual elements in an immiscible oil phase. The microscale hydrogel drop-carrier particles containing the voids or cavities may be manufactured using microfluidic droplet generators. The dropicles may be used to analyze single-entities (e.g., single-molecules and single-cells) and analytes.

  • Patent number: 9349891
    Abstract: An MTPV thermophotovoltaic chip comprising a photovoltaic cell substrate, micron/sub-micron gap-spaced from a juxtaposed heat or infrared radiation-emitting substrate, with a radiation-transparent intermediate window substrate preferably compliantly adhered to the photovoltaic cell substrate and bounding the gap space therewith.

  • Patent number: 8822813
    Abstract: An improved submicron gap thermophotovoltaic structure and method comprising an emitter substrate with a first surface for receiving heat energy and a second surface for emitting infrared radiation across an evacuated submicron gap to a juxtaposed first surface of an infrared radiation-transparent window substrate having a high refractive index. A second surface of the infrared radiation-transparent substrate opposite the first surface is affixed to a photovoltaic cell substrate by an infrared-transparent compliant adhesive layer. Relying on the high refractive index of the infrared radiation-transparent window substrate, the low refractive index of the submicron gap and Snell's law, the infrared radiation received by the first surface of the infrared radiation-transparent window substrate is focused onto a more perpendicular path to the surface of the photovoltaic cell substrate. This results in increased electrical power output and improved efficiency by the thermophotovoltaic structure.

  • Patent number: 8450598
    Abstract: A near-field energy conversion method, utilizing a sub-micrometer “near-field” gap between juxtaposed infrared radiation receiver and emitter surfaces, wherein compliant membrane structures, preferably fluid-filled, are interposed in the structure for maintaining uniform gap separation. Thermally resistant gap spacers are also used to maintain uniform gap separation. Means are provided for cooling a receiver substrate structure and for conducting heat to an emitter substrate structure. The gap may also be evacuated for more effective operation.
