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 ... -
Effective replacement of cetyltrimethylammonium bromide (CTAB) by mercaptoalkanoic acids on gold nanorod (AuNR) surfaces in aqueous solutions
(Royal Society of Chemistry, 2020)The highly packed cetyltrimethylammonium bromide (CTAB) bilayer built up on the surface of gold nanorods (AuNRs) when synthetized by the seed-mediated procedure hampers the complete ligand exchange under experimental ... -
Electrochemiluminescent nanostructured DNA biosensor for SARS-CoV-2 detection
(Elsevier, 2022)This work focuses on the development of an electrochemiluminescent nanostructured DNA biosensor for SARSCoV- 2 detection. Gold nanomaterials (AuNMs), specifically, a mixture of gold nanotriangles (AuNTs) and gold nanoparticles ... -
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 ...
