The present invention relates to: a paper-based surface-enhanced Raman scattering (SERS) substrate comprising metal nanoparticles, which are uniformly distributed and adsorbed on a designed pattern and have a diameter of 1 nm to 100 nm; a point-of-care (POC) diagnostic kit, comprising the paper-based SERS substrate; and a method for preparing the paper-based SERS substrate.

Paper-based surface-enhanced raman scattering substrate, and preparation method therefor

Disclosed herein is an X-ray source having cooling and shielding functions. The X-ray source includes an X-ray generation unit () which has one or more insulation columns () and emits X-rays in a vacuum; a cooling unit () which is provided around a periphery of the X-ray generation unit and removes heat generated from the X-ray generation unit; and a shielding unit () which is provided around a periphery of the cooling unit and shields an area exposed to X-rays other than the areas related to the emission of the X-rays.

X-ray source having cooling and shielding functions

The present invention discloses a digital X-ray source. The digital X-ray source includes an X-ray generation unit that emits X-rays, wherein the X-ray generation unit includes a cathode electrode; an emitter formed above the cathode electrode; an anode electrode located above the emitter; a gate electrode located between the emitter and the anode electrode; first and second focusing electrodes located between the emitter and the anode electrode; and an electrode connecting unit configured to include one or more insulating tubes capable of fixing and adjusting the locations of the gate electrode and the first and second focusing electrodes on the cathode electrode, and also configured to individually insulate and connect the cathode electrode, the gate electrode and the first and second focusing electrodes from and with electric lines
