PURPOSE: Magnetic nanoparticles and a method for diagnosing acute myocardiac infraction using the same are provided to combine antigen in blood with the myocardium indicator of the magnetic nanoparticles and measure the magnetic intensity of the magnetic nanoparticles. CONSTITUTION: Magnetic nanoparticles include superparamagnetic nanoparticle(110), a polymer film(120), and a myocardium indicator(130). The polymer film is coated on the outer circumference of the nanoparticle. The myocardium indicator is conjugated with the polymer film. The myocardium indicator is one of myoglobin, ck-mb, and cardiac troponin complex. The polymer film is formed based on hydrophilic polymeric materials. A method for diagnosing the acute myocardiac infraction includes the following: The magnetic nanoparticles are prepared. Blood is injected into the magnetic nanoparticles. The antigen in the blood is reacted with the myocardium indicator of the magnetic nanoparticles. Reacted magnetic nanoparticles are extracted. Magnetic field is applied to the extracted nanoparticles. The magnetic intensity of the magnetic nanoparticles is detected. Based on the detected magnetic intensity, the acute myocardiac infraction is diagnosed. |
