| Abstract Scope |
Magnetic micro and nano particles are widely used as biomarker proteins, drug carriers, and hyperthermia to name some applications [1]. In most of the cases, the particles must be to be integrated into simple inexpensive systems for accurate, sensitive detection. Depending on the application, the magnetic fields that must be detected can be as low as few picoTesla. It is well known that the giant magnetoimpedance can measure such low fields with proper signal conditioning [2]. However, there are some challenges that must be solved as miniaturization and integration, the need of biasing with a low field, and high frequency excitation with complex electronics for conditioning the electrical signal. Moreover, the trend on disposable devices rather than lab on a chip device means that the disposable device must power wirelessly and be flexible.
