  • Publication number: 20230271186
    Abstract: A point-of-care device for detecting nucleic acid is disclosed. The point-of-care device for detecting nucleic acid according to an exemplary embodiment of the present invention includes a rotating body in which a plurality of test tubes containing a sample mixed with heat-generating particles that generate heat when irradiated with light beams are radially coupled around a rotation shaft; a first actuator for rotating the rotating body such that the test tube rotates about the rotation shaft; and an irradiation module for irradiating the light beams to an irradiated area which is set on a rotation path of the test tube, wherein the rotation path includes a non-irradiated area to which the light beams are not irradiated, and wherein the test tube proceeds through the irradiated area and the non-irradiated area on the rotation path according to the rotation of the rotating body.

  • Publication number: 20110290184
    Abstract: Provided is a poly silicon deposition device, which includes an electrode part, a silicon core rod part, a silicon core rod heating part, a gas supply pipe, and a gas injection part. The electrode part includes a first electrode and a second electrode which are disposed in a bottom of a reactor including a gas inlet for introducing source gas, a gas outlet for discharging gas, and a heating material inlet for introducing a heating material, and are spaced a predetermined distance from each other. The silicon core rod part receives electric current from the first electrode and transmits the electric current to the second electrode to generate heat. The silicon core rod heating part is spaced a predetermined distance from the silicon core rod part and surrounds the silicon core rod part and includes a heater receiving the heating material introduced through the heating material inlet of the reactor.
