Plasmonic On-Demand Design via 3D Nanoprinting

Plasmonic nanoparticles have unique optical properties due to their size and shape, and are increasingly being incorporatedinto commercial products and technologies, ranging from photovoltaics to biological and chemical sensors[1]. The control on shifting and tuning of the plasmonic response depend highly on the abilities to control the finalshape of the nano-particles in every detail. Expansion towards the third dimension in cotnrast to traditionally planarplasmonic structures crucially enhances the design possibilities. 3-D nano-printing via focused electron beam induceddeposition (3D-FEBID) allows flexible fabrication with nanoscale precision [2]. In addition, it has been proven to be aversatile fabrication method to achieve on-demand design of plasmonically active nanostructures [3-6].
