Surface Protection of Quaternary Gold Alloys by Thiol Self-Assembled Monolayers
(MDPI, 2022)
This work deals with a physical and chemical surface characterization of quaternary 18K, 14K, and 9K gold alloys and pure polycrystalline gold substrates. Surface microstructure and composition are evaluated by scanning ...
Efficient formation of poly(ethylene glycol) polymer brushes on gold electrodes via surface-initiated electrochemically mediated ATRP (SI-eATRP)
(Elsevier, 2023)
Electrochemically mediated surface-initiated atom transfer radical polymerization (SI-eATRP) is an interesting grafting from technique used to grow, in a controlled way, polymeric films from a wide range of surfaces, ...
Study of the Self-assembly Process of an oligo(ethylene glycol)-thioacetyl Substituted Theophylline (THEO) on Gold Substrates.
(Elsevier, 2018)
A new oligo(ethylene glycol)-thioacetyl substituted theophylline (THEO) has been synthesized and used to form self-assembled monolayers (SAMs) on different gold substrates. The THEO-SAMs formed are compact and passivate ...
Characterization of self-assembled Bis[2-(2-bromoisobutyryloxy) undecyl] disulphide (DTBU) on gold surfaces suitable for use in surface-initiated atom transfer radical polymerization (SI-ATRP)
(Elsevier, 2022)
Bis[2-(2-bromoisobutyryloxy) undecyl] disulphide (DTBU) is an initiator for surface-initiated atom transfer
radical polymerization (SI-ATRP) able to functionalize metal surfaces through formation of self-assembled
monolayers ...
Effects of the potential and the electrolyte nature in the integrity of the O-(2-Mercaptoethyl)-O′-methyl-hexa(ethylene glycol) self-assembled monolayer by electrochemical impedance spectroscopy
(Elsevier, 2022)
This work addresses an in-deep study of the ionic conductive properties of the O-(2-Mercaptoethyl)-O’-methyl-hexa(ethylene glycol)-self assembled monolayer (EG7-SAM) by electrochemical impedance spectroscopy in a range of ...
Characterization of a self-assembled monolayer of O-(2-Mercaptoethyl)-O′-methyl-hexa(ethylene glycol) (EG7-SAM) on gold electrodes
(Elsevier, 2021)
The modification of surfaces by polyethylene glycol (EGn) is an approach used to reduce the antifouling effects of these materials in a biological medium. It has been found that the packing density and conformational order ...
Distinct thermoresponsive behaviour of oligo- and poly-ethylene glycol protected gold nanoparticles in concentrated salt solutions
(Royal Society of Chemistry, 2021)
In this work, the methoxy terminated oligo- and polyethylene glycol of different chain lengths (EGn, n ¼ 7,
18, 45 and 136) is grafted on AuNP surfaces under conditions where they attain maximum grafting densities.
These ...
Electrochemical evaluation of the grafting density of self-assembled monolayers of polyethylene glycol of different chain lengths formed by the grafting to approach under conditions close to the cloud point
(Elsevier, 2022)
Grafting densities of polymers on gold surfaces are important parameters that inform about the chain conformation adopted by the chains, either mushroom or brush conformation. Most of the literature reports on this topic ...
Influence of Patterning in the Acid–Base Interfacial Properties of Homogeneously Mixed CH3- and COOH-Terminated Self-Assembled Monolayers
(American Chemical Society, 2018)
The acid/base interfacial behavior of mixed self-assembled monolayers (SAMs) of 1-decanethiol (DT) and 11-mercaptoundecanoic acid (MUA) formed on gold from a micellar medium has been characterized by electrochemical impedance ...
Self-assembled monolayers of O-(2-Mercaptoethyl)-O′-methyl-hexa(ethylene glycol) (EG7-SAM) on gold electrodes. Effects of the nature of solution/electrolyte on formation and electron transfer blocking characteristics
(Elsevier, 2022)
The self-assembly of O-(2-Mercaptoethyl)-O’-methyl-hexa(ethylene glycol) (EG7) on gold substrates produces monolayers whose structure should depend primarily on the solvents used for their formation. Although this should ...
