Keywords: magnetic nano particles(MNP), diagnostics, PCR


Magnetic Nano Particles (MNP) for diagnostics had been fabricated by coating the particle s surface with specific coupling agents . This agent allows the pulling the virus containing DNA and/or RNA molecules off the patient blood . The viruses were isolated from the MNP to be magnified by the PCR technique . It is found that this technique can be more effective compared to the conventional diagnostic process at least 60X or more based on the concentration of the detected viruses . The succesful viruses for the diagnostics include hepathetis B, hepathetis C, koch, diarhea in tropical area etc ..MNP can be selected from a variety of nano particles including solid phase carbon nano tube, Ni oxide, iron oxide and Co oxide
