Researchers unveil mechanism to obtain metal 'nanoscrews' Elhuyar Fundazioa via Phys.org Led by the Ikerbasque professor Luis Liz-Marzán, researchers at the Centre for Cooperative Research in Biomaterials CIC biomaGUNE have developed a mechanism by which gold atoms are deposited by means of chemical reduction onto previously formed gold nanorods to produce a quasi-helicoidal structure (the particles acquire chirality). This geometry enables these "nanoscrews" to interact with circularly polarized light much more efficiently than what is achieved with any other known object. READ MORE
