Masahito Hayashi 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).

  • Patent number: 9109197
    Abstract: Provided is a device for concentrating and separating cells, which has a function for continuously concentrating cells; a function for then continuously arranging the concentrated cells in predetermined regions of a flow path; a function for simultaneously identifying shape and fluorescent emission in one-cell units on the basis of cell concentration and purification images, which serve to continuously separate and purify cells that have different properties in that they are either attracted to or repelled by an induction electrophoresis force of a predetermined frequency; and a function for identifying cells on the basis of this shape and fluorescent emission information and thereby separating and purifying the cells.
    Type: Grant

  • Patent number: 9023294
    Abstract: Provided is a cell concentration and purification device, having: a function of continuously concentrating cells; a function of then subsequently disposing the cells continuously in a specific region of a channel; a function of simultaneously recognizing, based on an image, the shape and fluorescence emission of each single cell; and a function of recognizing the cells and then separating and purifying the same based on the data relating to the shape and fluorescence emission thereof.

  • Publication number: 20130314526
    Abstract: Provided is a cell concentration/purification device having a function of successively locating cells in a specific area of a microchannel, and a function of sequentially capturing cell images by use of light from a plurality of monochromatic light sources on an image basis, and performing comparative analysis of the cell images to recognize individual cells based on information on the shape of the cells and an absorption spectral distribution of the cells or inside of the cells, thereby selectively separating/purifying the cells.
