Abstract
The Single-walled carbon nanotube (SWCNT) based on 1-Amino-nonenthiol (ANT) was highly organized (nano level) forming an aggregated SWCNT-ANT self-assembled layer (SAL) on gold substrates. The fabricated nanosurfaces were investigated specially using FT-IR, cyclic voltammetry (CV), Raman spectroscopy, electrochemical quartz crystal microbalance (EQCM), and atomic force microscopy (AFM) techniques. The perpendicular aggregation of SWCNT-ANTs on chemically polished Au(111) substrates was fabricated by their spontaneous chemical bonding between carboxyl derivatized SWCNT-COOH and ANT SAL on Au(111), via peptide bonds, or directly by synthesized SWCNT-ANT composites. Raman spectroscopy and AFM surface images clearly revealed that the aggregated SWCNTANT (dia. 25-70 nm) has been organized on gold(111) substrates, forming a SAL with a random orientation.
