1. Caracterização eletroquímica de uma monocamada auto-organizada mista composta por ácido 3-mercaptopropiônico e ácido 11-mercaptoundecanóico / Electrochemical characterization of a mixed 3-mercaptopropionic and 11-mercaptoundecanoic acids self-assembled monolayer
Monocamadas auto-organizadas formadas pela quimissorção de alcanotióis sobre ouro apresentam estruturas bem definidas, organizadas e reprodutíveis. As propriedades de SAMs, aliadas à facilidade de síntese, têm atraído o interesse da comunidade cientifica o que ocasionou um grande avanço na área de nanotecnologia, especialmente em engenharia de supe

2. Eletrodos modificados com monocamadas auto-organizadas de alcanotióis: uma abordagem sobre a transferência eletrônica / Electrode surface modified with alkanothiols self-assembled monolayers: an electron transfer approach
The modification of electrode surfaces with self-assembled monolayer (SAM) is one of the top subjects in electrochemistry and electroanalysis, mainly due to its much enhanced biocompatibility. In this study, the focuses are centered in the electron transfer through SAMs of alkanothiols assembled onto gold electrode surfaces. In order to investigate the elect

3. Effect of Substratum Surface Chemistry and Surface Energy on Attachment of Marine Bacteria and Algal Spores
Two series of self-assembled monolayers (SAMs) of ω-substituted alkanethiolates on gold were used to systematically examine the effects of varying substratum surface chemistry and energy on the attachment of two model organisms of interest to the study of marine biofouling, the bacterium Cobetia marina (formerly Halomonas marina) and zoospores of the alga U

4. Supported phospholipid/alkanethiol biomimetic membranes: insulating properties.
A novel model lipid bilayer membrane is prepared by the addition of phospholipid vesicles to alkanethiol monolayers on gold. This supported hybrid bilayer membrane is rugged, easily and reproducibly prepared in the absence of organic solvent, and is stable for very long periods of time. We have characterized the insulating characteristics of this membrane by

5. Bacterial adhesion to hydroxyl- and methyl-terminated alkanethiol self-assembled monolayers.
The attachment of bacteria to solid surfaces is influenced by substratum chemistry, but to determine the mechanistic basis of this relationship, homogeneous, well-defined substrata are required. Self-assembled monolayers (SAMs) were constructed from alkanethiols to produce a range of substrata with different exposed functional groups, i.e., methyl and hydrox
