Patent ID: 8388725

Claim:
A method for manufacturing metal nanoparticles, comprising: preparing a solution containing a precursor of metal nanoparticles: transferring the solution containing a precursor of metal nanoparticles to a first heating part including a reactor channel with a diameter of 1 to 50 mm; pre-heating the solution containing a precursor of metal nanoparticles at the first heating part to a temperature range where any particle is not produced; transferring the solution containing a precursor of metal nanoparticles to a second heating part which includes a reactor channel with a diameter of 1 to 50 mm and is heated to a temperature range where particles are produced; producing metal nanoparticles by heating the solution containing a precursor of metal nanoparticles at the second heating part; and collecting the produced metal nanoparticles by employing a cooler.
