Abstract :
In the future, devices based on lab-on-a-chip, compact and inexpensive detection units are required that directly translate the abundance of certain biomolecules into an electronic signal. By detecting specifically bound magnetic labels with magnetoresistive sensors, a versatile platform can be designed that fulfils those requirements and even enables on-chip manipulation of biomolecules by suitable magnetic gradient fields. In this paper, sensitive recognition of magnetic label by magnetoresistive sensor based on giant magnetoresistance (GMR) have been discussed.
