Laser fabrication of large-scale nanoparticle arrays for sensing applications

ACS Nano. 2011 Jun 28;5(6):4843-9. doi: 10.1021/nn2009112. Epub 2011 May 5.

Abstract

A novel method for high-speed fabrication of large scale periodic arrays of nanoparticles (diameters 40-200 nm) is developed. This method is based on a combination of nanosphere lithography and laser-induced transfer. Fabricated spherical nanoparticles are partially embedded into a polymer substrate. They are arranged into a hexagonal array and can be used for sensing applications. An optical sensor with the sensitivity of 365 nm/RIU and the figure of merit of 21.5 in the visible spectral range is demonstrated.
