<p>A noble metal nano colloid maker includes a consumable cartridge where noble metal wire is bonded; a cartridge holder part that enables attaching or detaching the cartridge and allows it to be connected to the high- voltage energy electrode part; a cartridge-moving part that moves the cartridge up and down; a disconnection-sensing part that detects whether the noble metal wire attached to the consumable cartridge electrode is disconnected; a high-voltage charging and discharging part that controls the charging and discharging of electric energy through a 2-step method relay switch and a surge killer designed to protect the circuit from the resulting surge and noise when underwater plasma occurs; and a water cup weight-sensing part that detects whether the water cup contains a fixed amount of water, thereby allowing the simple production of noble metal nano colloids at home.</p>
