Nano-contact printing of DNA monolayers
… printing through the printing of oligonucleotide monolayers. Eight pattern transfers were made with one master copy and the oligonucleotide surface coverage was analyzed using tapping mode atomic force microscopy (AFM). The percent coverage of oligonucleotide was then calculated from the tapping …

AFM-Assisted Nanofabrication using Self-Assembled Monolayers
… and proteins to patterned self-assembled monolayers. A scanning probe nanografting technique was employed to produce patterns of various sizes, down to 10 nm. Thus, we are able to demonstrate a degree of surface patterning which is an order of magnitude smaller than that used in the …

Self-Assembled Monolayers As Models For Silica
… elemental microanalysis. Self-assembled monolayers (SAMs) on gold were prepared using thiols 1, 2, and 3. SAMs were characterized using reflectance-absorbance infrared spectroscopy (RAIRS). Diagnostic vibrational modes were assigned by comparing RAIRS spectra to normal mode frequencies …

Interfacial spallation/delamination properties of self-assembled monolayers
Self-assembled monolayers (SAMs) are short (nanometer-size) organic chains terminated by functional groups that can be selected to tailor the electrical, thermal and/or mechanical properties of interfaces. In this thesis, we investigate how the presence of SAMs affects the failure properties of …

Self-Assembly in Physisorbed Monolayers via Directional Intermolecular Interactions
… structure of self-assembled physisorbed organic monolayers is considered. These layers exhibit only weak, non-directional interactions with the substrate, and so their structure is driven by the adsorbate-adsorbate interactions. In the initial phase of work, scanning tunnelling microscopy (STM) …

N-heterocyclic Carbene Synthesis Towards Self-Assembled Monolayers on Gold
Modifying surfaces with self assembled monolayers (SAMs) is a simple and effective way to create functional materials. Traditionally compounds containing a thiol head group are used to generate SAMs on gold surfaces. However, a recent discovery by the Crudden lab demonstrated increased bond …
