New Biosensor for Phenols Compounds Based on Gold Nanoparticle-Modified PVC/TTF-TCNQ Composite Electrode
(Electrochemical Science Group (ESG), 2012)
A gold nanoparticle-modified PVC/TTF-TCNQ composite electrode with tyrosinase enzyme is proposed as electrochemical biosensor for detecting phenolic compounds in musts and wines samples using phenol and catechol as standards. ...
Electrocatalytic Oxidation of Acetaminophen on a PVC/TTF-TCNQ Composite Electrode Modified by Gold Nanoparticles: Application as an Amperometric Sensor
(Electrochemical Science Group (ESG), 2011)
This work shows the electrocatalytic activity towards the oxidation of acetaminophen of a composite electrode PVC/TTF-TCNQ modified with gold nanoparticles. Owing to a good linear relationship between acetaminophen ...
Mimicking the bioelectrocatalytic function of recombinant CotA laccase through electrostatically self-assembled bioconjugates
(Royal Society of Chemistry, 2018)
Unprecedented 3D nanobiosystems composed of recombinant CotA laccases and citrate-stabilised gold nanoparticles have been successfully achieved by an electrostatic self-assembly strategy. The bioelectrochemical reduction ...
Influence of the synthesis route on the electrocatalytic performance for ORR of citrate-stabilized gold nanoparticles
(Elsevier, 2022)
Citrate-stabilized gold nanoparticles (AuNPs) were synthesized by two different citrate-based reduction methods, namely a one-pot wet chemical synthesis (Turkevich method) and seed-mediated growth (Bastús method). Although ...
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 ...
Behind the Optimization of the Sensor Film: Bioconjugation of Triangular Gold Nanoparticles with Hemoproteins for Sensitivity Enhancement of Enzymatic Biosensors
(MDPI, 2023)
Electrochemical biosensors are widely used in a multitude of applications, such as medical, nutrition, research, among other fields. These sensors have been historically used and have not undergone many changes in terms ...
Hemoglobin becomes electroactive upon interaction with surface-protected Au nanoparticles
(Elsevier, 2018)
In this work, we report on the electrochemical behavior of bioconjugates prepared with gold nanoparticles
(AuNP) capped with three different molecular layers (citrate anions, 6-mercaptopurine and ω-mercaptoundecanoic
acid) ...
Hemoglobin bioconjugates with surface-protected gold nanoparticles in aqueous media: The stability depends on solution pH and protein properties
(Elsevier, 2017)
The identification of the factors that dictate the formation and physicochemical properties of protein-nanomaterial bioconjugates are important to understand their behavior in biological systems. The present work deals ...
