The aim of this report is to prove that polarimetric surface plasmon resonance imaging (P-SPRI) is able to characterize dynamically the anisotropy of micro and nanoobjects. Micro and nanoparticles were assembled into ¯laments at a speci¯c location on a support, using a combination of magnetic ¯eld, amine based chemistry and orthogonal surface chemistry. After immobilization of the ¯laments onto gold pads, they were actuated by a magnetic ¯eld and validated the P-SPRI system.
