Abstract :
We have proposed two medical applications using ultra-small magnetic particles. One is a lymph-node detection system and the other is a DNA probing system. In both cases, magnetic particles are detected by a sensitive high Tc SQUID magnetic sensor. We demonstrate that lymph nodes containing particles extracted from the rat were successfully measured by a SQUID system. In the application of DNA detection system, a preliminary experiment has been done. These results are described in this paper.
