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,...

This paper presents a case report where the influence of plaque accumulation and overload on a dental implant was observed. The patient presented crown loss on one implant affected by peri-implant bone resorption and gingival inflammation associated with poor oral hygiene. After 12 months a single crown was delivered, but as soon as the...

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...
