Morphological and Mechanical Characterization of DNA SAMs Combining Nanolithography with AFM and Optical Methods

Pinto, Giulia Canepa, Paolo Canale, Claudio

The morphological and mechanical properties of thiolated ssDNA films self-assembled at different ionic strength on flat gold surfaces have been investigated using Atomic Force Microscopy (AFM). AFM nanoshaving experiments, performed in hard tapping mode, allowed selectively removing molecules from micro-sized regions. To image the shaved areas,...

Functionalizing gold with single strand DNA: novel insight into optical properties via combined spectroscopic ellipsometry and nanolithography measurements

PINTO, GIULIA Parisse, Pietro Solano, Ilaria

We have studied the self-assembly of 22-base oligonucleotides bound by a short alkyl thiol linker (C 6 -ssDNA) on flat Au films. The self-assembled monolayer (SAM) was modified by addition of a spacer (mercaptohexanol, MCH). Molecular depositions were monitored in situ by spectroscopic ellipsometry (SE). SAMs were characterized in a liquid...
