We describe the development of core-shell amphiphile chains based on the fabrication of di-functional spheres for technology and bioanalytical application. The structure design involves the combination of magnetic force and biological or chemical interaction. Two different micro/nano particles were chosen. One of them has magnetic components. Biological or chemical interaction couples these two functional spheres. Under the external magnetic field, the particles were oriented into chains and amphiphile rods formed. This combination provides new avenues to achieve multifunctional rods, the most important of which is that the shell sphere can serve as a recognition element for directed analyte monitoring. Different micro/ nano sphere materials used for assembly, such as metal, polymer or even silica gives them widely different potential applications for miniaturized device construction, including combinations of electronics, optics, sensors and analytical applications.
