Highly-ordered gold nanoparticles surface fabrication for localized surface plasmon resonance sensors
Original language description
We present a technology to fabricate highly-ordered gold nanoparticle surfaces and to transfer them onto transparent polymer substrates suitable for transmission localized plasmon resonance spectroscopy and sensing. The nanoparticles are synthetized by utilizing the solid-state dewetting process of thin gold layers over nanodimpled aluminum templates. These templates were prepared by a porous anodizing of an aluminium sheet followed by selective etching of formed porous anodic alumina. Because of that, nanoparticle layers have well-ordered hexagonal alligment and do not contain additional organic compounds. Nanoparticles formed this way were directly transferred to a PDMS (polydimethylsiloxane) blocks, where their localized surface plasmon resonance (LSPR) transmittance spectra were measured. It was proved, that the presented fabrication technology enables proper control over the nanoparticle size and interparticle distance over a large surface area (cm 2 range), and that it is possible to synthetize
