Patents by Inventor Genqian LI

Genqian LI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240082836
    Abstract: Introduced here are rotors that can be placed inside of microplate wells that include liquid samples. Each rotor can be comprised of a ferromagnetic material. Accordingly, when a rotor is subjected to an external rotational magnetic field, the rotor spins and agitates the liquid sample inside the corresponding well. The spin speed may be adjusted by changing the rotation speed, direction, and/or orientation of the external rotational magnetic field. The rotor typically includes a central cavity within which a probe can be suspended during the biochemical test.

  • Patent number: 11879901
    Abstract: This invention relates to an apparatus for conducting immunoassay test. The apparatus includes a groove unit having a groove along a vertical direction configured to hold a rod-shaped portion of a probe along the vertical direction, and a push pin configured to move along a horizontal direction, the push pin being capable of residing at a first position and a second position. A tip of the push pin is capable of pressing the rod-shaped portion of the probe against the groove when the push pin resides at the first position. The distance between the tip of the push pin and the groove is larger than a diameter of the rod-shaped portion of the probe when the push pin resides at the second position.
