Abstract
We have compared the adsorption behaviors between single-walled carbon nanotube (SWCNT) powders and thin films with amino acids such as phenylalanine and glycine by using the X-ray absorption near edge structure (XANES) spectroscopy. On SWCNT powders very weak adsorption occurs as confirmed also by studies at high solution concentrations. The comparison of the adsorption behaviors with previous reports for thin films of SWCNTs shows that, due to their compact structure, thin films favor the adsorption of amino acids and represent themselves good candidate for a reliable evaluation of the interaction among amino acids and SWCNTs.
