Nanomagnetics are potential new era in Nano-biotechnology for not only 
in industrial applications especially related with information science 
and technology, but also in bioassays related with translocation of 
magnetic carriers for biomolecules analysis, biochip/sensors and for 
multiplexed bio-recognition channels/platforms. At present, a small 
number of groups in the worldwide have succeeded to enhance the sensor 
resolution to recognize biomolecules down to a few pairs of probe-target 
molecules.

In this talk, firstly, I would like to give an overview on the current 
status of magnetic bioassays, and our approach to enhance sensor 
resolution and method for biomolecular detection performed in on our 
Lab., such as high resolution spintronics sensor, magnetic nanoparticle 
labels/carriers, multi-segmented barcode nanowires etc. Secondly, I will 
focus on a novel smart magnetophoresis micro system for translocation of 
magnetic carriers, including the magnetic behavior of magnetic carrier 
at specific binding sites of the sensor surface on a single chip for 2-D 
bioassay applications. For the smart magnetophoresis we have used soft 
NiFe elliptical (9 ?m×4 ?m×0.1 ?m) elements as magnetic pathways 
(CNU-express pathways for biomolecules transportation). The 
lithographically patterned NiFe elliptical pathways can generate 
different stray magnetic fields when they are subjected to the external 
rotating magnetic field. The inhomogeneity in stray magnetic fields 
governs the magnetic carriers (beads/nanowires) motion in a controllable 
way on the CNU express pathways.
