Flexible and stretchable polymers with embedded magnetic nanostructures.

A novel pathway is presented to transfer and embed functional patterned magnetic nanostructures into flexible and stretchable polymeric membranes. The geometrical and magnetic properties are maintained through the process, realized even directly inside a microfluidic channel. These results pave the way to the realization of smart biomedical systems and devices based on the integration of magnetic nanostructures into new classes of substrates.
