Abstract
A novel technique to realize large quantities of stacked multifunctional anisotropic nanoparticles with narrow size distribution is presented. Through the combination of Ultraviolet Nano-Imprint Lithography (UV-NIL), physical vapor deposition and subsequent lift-off processes we fabricate and disperse these particles in solution for the use in biomolecular sensing applications. Compared to chemical nanoparticle synthesis our approach holds several advantages. First, one can control the nanoparticle shape by choosing an appropriate nanopattern for the UV-NIL process. Second, we can choose the composition of the nanoparticles as the materials are deposited layer-wise by sputter deposition. Third, we can fabricate nanoparticles with very small geometrical variations. This is in contrast to chemical synthesis methods where the layer thicknesses and particle size distribution are harder to control.
