Abstract
The invention combines (A) capabilities in fabrication, characterization, and manipulation of single domain magnetic nanostructures, with (B) the use of binding chemistry of biological molecules to modify the magnetic nanostructures into magnetic sensors and magnetically controllable nanoprobes. A biological characterization scheme is realized by combining nanomanipulation and observation of small magnetic structures in fluids. By coating nanomagnets with biological molecules, ultra-small, highly sensitive and robust biomagnetic devices are defined, and molecular electronics and spin electronics are combined. When these nano-sensors are integrated into microfluidic channels, highly efficient single-molecule detection chips for rapid diagnosis and analysis of biological agents are constructed.
