For the magnet sensor detection of useful magnetic nanoparticles, especially in the case of a biosensor applications

摘要

It is a process for the production of magnetic nanoparticles (mnps), which results in a very sensitive mnps, in the case of a plurality of diagnosis - and analytical methods can be used. The mnps have to superparamagnetism, and are used especially in the case of giant magnetoresistance - (gmrs) - sensors use. The mnps are formed by a process, which allows the size of nanoparticles to a range of from 10 to 20 nanometers with a very small size distribution of + / – 2 nanometers to adjust or less. The mnps with a plurality of markings can be marked in a given and are therefore used in many analytical tests, cell sorting techniques, imaging methods, medicaments administration method and cancer treatments use. The novel mnps, in magnetic field strengths of 2000 oe or less are detected.
