An electrochemical sensor for homocysteine detection using gold nanoparticle incorporated reduced graphene oxide

A sulfonated graphene supported nano copper MoS2 network for non-enzymatic simultaneous sensing of dopamine and serotonin

“…The presence of abundant active sites in the MoS 2 /SG/Cu nanocomposite resulted in improved electronic properties and electron transfer kinetics awarding a highly calibrated sensing probe. 65 Thereby, the MoS 2 /SG/Cu nanocomposite-modified GCE was used as the working electrode for subsequent electrochemical studies.…”

An Amperometric Biomedical Sensor for the Determination of Homocysteine Using Gold Nanoparticles and Acetylene Black-Dihexadecyl Phosphate-Modified Glassy Carbon Electrode

“…In 2018, Rajaram and Mathiyarasu reported an electrochemical sensor for the quantification of HcySH using Au nanoparticles incorporated into a reduced graphene oxide -modified glassy carbon electrode (AuNP/rGO/GCE) [ 27 ]. A significant advantage of the reported sensor was the low overpotential that was beneficial for good selectivity.…”

Development of a colloidal gold strip assay for the detection of total homocysteine in serum samples

“…9,10 It is necessary therefore to determine the Hcy content in the human body using an appropriate methodology. In recent years, with more attention being paid to cardiovascular, cerebrovascular and neurological diseases, an increasing number of methods have been developed to detect Hcy including HPLC-MS/MS, 11 electrochemical sensors, 12 fluorescent probes 13,14 and others. 15,16 HPLC-MS/MS is a classical accurate quantitative method, but it relies on complex instruments and skilled professionals for its operation.…”
