UV spectra of amino acid in immobilized at nanoparticles formation through Nanosphere Lithography (NSL) by plasma treatment

Nanosphere lithography, as one of the high-resolution and cost-effective technologies, has attracted much research effort from both industry and academics [1]. It utilizes the self-organization of monodispersed nanospheres as an inverse pattern whose deposition channels are defined by interstitial voids between nanospheres [1]. The size of such deposition channels in the pattern is proportional to the size of the spheres. In this study, 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. UV spectra of protein that immobilized to the nanoparticles arrays under UV spectrums were studied.
