Abstract
The modifying of nanospheres structures by plasma treatments to the fabricated nanoparticles arrays by Nanosphere Lithography (NSL) techniques to create Periodic Particles Arrays (PPAs) with different size, shape and orientation. Spectra of amino acid that immobilized to the nanoparticles arrays under Ultra Violet (UV) spectrums were studied. The PPAs with different sizes, shapes and orientation were fabricated by plasma treatment of 5 sec, 7 sec and 10 sec to the Polystyrene Nanosphere (PSN). Plasma treatment will effect to the PSN including etching part of the PSN to produce a much bigger channel to the single layer template of the PSN. Metal was deposited at interstitial sites between of the polymer balls and later removed by dissolving them in organic solvent, leaving a hexagonal pattern of metal structures at the interstitial sites. The nanoparticles immobilized with the standard amino acid, which later investigated under UV spectrums. The spectrums shows the possibilities use as biosensor devices.
