Abstract: A cell transformation cartridge according to the present invention includes a body unit, in which a cell flow path, a material flow path, and a resultant flow path that meet one another are formed; and an electric field forming unit, which includes an electrode being connected to the body unit to create an electric field in a resultant flow path, wherein the cell flow path and the material flow path are formed in a shape that converges to the resultant flow path, wherein the resultant flow path includes a mixing flow path extending from a location being connected to the cell flow path and the material flow path, and wherein the thickness of the mixing flow path is smaller than that of the cell flow path.

Abstract: A method for quantifying a content of hydrophobic components contained in a liquid using a contact area diffusion factor (CADF) of a droplet of the liquid to a solid surface is provided. In addition, the obtained content of the hydrophobic components provides information about prediction for possibility of developing a metabolic disease or dementia, or information about the incidence or progression of a metabolic disease or dementia.

Abstract: The present invention relates to a device for putting material into a cell to be modified. More particularly, the present invention is directed to a device formed within one solid material and comprises, a first passage on which the cell passes; a second passage on which the material passes and connected to the first passage at a position randomly selected between both ends of the first passage; and an apparatus which applies pressure difference or electric potential difference on the first passage and the second passage, and is also directed to a process for making the device.

Abstract: The present invention relates to a viscosity measuring method. More particularly, the present invention relates to a viscosity measuring method comprising: (i) a step of acquiring an image of a droplet in a static state without vibration; (ii) a step of using a vibrator to vibrate the droplet, and acquiring an image of a dynamic state in which the droplet is maximally extended in a horizontal direction or maximally extended in a vertical direction; (iii) a step of obtaining the static curvature change rate and the dynamic curvature change rate of the interface of the droplet from the images acquired in steps (i) and (ii); and (iv) a step of substituting the ratio of the static curvature change rate to the dynamic curvature change rate of the droplet interface into an interaction equation compensating for the vibrator, so as to obtain the viscosity of the droplet.
