Gold nanoparticles motion controlled by transverse spin momentum of evanescent waves in biomedical applications

摘要

The theoretical and experimental confirmation of the existence of a transverse spin momentum in an evanescent waveexcited above the surface of a birefringent biological section is suggested in this research work. The possibility ofcontrolling gold nanoparticles by the vertical spin of an evanescent wave in a surrounding fluid of tissue near the surfacelayer of the section is demonstrated.
