SPR-inducing reactor for synthesizing magnetic nanoparticles

摘要

PURPOSE: A surface Plasmon resonance induced reactor for synthesizing magnetic nano-particles is provided to effectively synthesize nano-particles using a gold nano-rod inducing the generation of heat. CONSTITUTION: A surface Plasmon resonance induced reactor for synthesizing magnetic nano-particles manufactures a mono-dispersed gold nano-rod of several nano meters. The gold nano-rod is fixed on a substrate such as a transparent glass slide or a quartz cell in a near infrared ray region. A light emitting element is formed for laser in a near infrared ray region which is in a range between 800 and 1200nm and generates high temperature heat to a specific part based on optical fiber. Heat is locally generated at an accurate position in the reactor and induces the boiling of an organic solvent and the thermal deposition of precursors. Nano-particles of various shapes and sizes are synthesized. Pure nano-particles are eliminated based on centrifugal separation.
