“…In alkaline medium, the rate of Au catalyzing the oxidation of glucose is better than that of other Group VII noble metals such as Pt. Therefore, Au is also an excellent modifier for the preparation of enzyme-free glucose sensors [9] . Yusuf et al [9] de-posited Au nanoparticles on carboxylated graphene oxide (GO-COOH) and modified them on glassy carbon electrodes as working electrodes for glucose sensors.…”

“…However, such targeted action requires significant knowledge and data for the particular morbidity and effected tissue. One of the most notable and common implementations of precision medicine, currently, is in the treatment of diabetes [ 47 , 48 , 49 , 50 ]. Continuously monitoring glucose systems provide real time data of blood glucose levels for actionable response of insulin injection.…”

Although total hip arthroplasty (THA) is considered to be the most successful orthopedic operation in restoring mobility and relieving pain, common Metal-on-Metal (MoM) implants developed in the past decade suffer from severe inflammatory reactions of the surrounding tissue caused by the premature corrosion and degradation of the implant. A substantial amount of research has been dedicated to the investigation of mechanically driven fretting and crevice corrosion as the primary mechanism of implant failure. However, the exact mechanism by which hip implant breakdown occurs remains unknown, as current in vitro fretting and crevice corrosion studies have failed to completely replicate the corrosion characteristics of recovered implants. Here, we show that minor electric potential oscillations on a model hip implant replicate the corrosion of failed implants without the introduction of mechanical wear. We found in a controlled lab setting that small electrical oscillations, of similar frequency and magnitude as those resulting from ambient electromagnetic waves interacting with the metal of the implant, can force electrochemical reactions within a simulated synovial fluid environment that have not been previously predicted. In lab testing we have shown the replication of titanium, phosphorous, and oxygen deposition onto the surface of ASTM astm:F75 CoCrMo metal alloy test specimens, matching the chemical composition of previously retrieved wear particles from failed patient prosthetics. Our results demonstrate that the electrical activity and ensuing electrochemical activity excites two corrosion failure modes: direct dissolution of the medically implantable alloy, leaching metal ions into the body, and surface deposition growth, forming the precursor of secondary wear particles. We anticipate our findings to be the foundation for the future development and testing of electrochemically resistant implantable material.

“…There are many kinds of electroactive materials employed to construct a sensitive and simple electrochemical sensors such as conducting polymers (Tabrizi et al, 2016;Pothipor et al, 2018;Putnin et al, 2018;Chanarsa et al, 2020), metal nanoparticles (NPs) (Hoa et al, 2015;Jeong et al, 2018;Tran et al, 2018;Dilmac and Guler, 2020), metal oxide nanostructures (Dong et al, 2021;Yang et al, 2021), and carbon nanoarchitectures (Pothipor et al, 2015;Li et al, 2016;Shen and Shen, 2019). Many attempts aim to develop the materials offering the sensors with LODs (Li et al, 2014(Li et al, , 2016Shen et al, 2015;Zhu et al, 2015;Montes et al, 2016;Tang and Ma, 2016;Zhang et al, 2016;Dong et al, 2017;Han et al, 2017;Barman et al, 2020).…”

“…To date, many electrochemical platforms are widely used to immobilize antibodies for construction of the immunosensor, including redox hydrogel (Li and Ma, 2017 ; Tang et al, 2017 ), CuPdPt nanowire networks (Wen et al, 2018 ), AuPd NP-multiwalled carbon nanotube (CNT) composite/ferrocenecarboxaldehyde/chitosan hybrid hydrogel (Yin et al, 2018 ), AgPt nanorings supported on rGO (Wang et al, 2018 ), and high quality graphene oxide (GO) (Jumpathong et al, 2016 ; Norfun et al, 2016 , 2017 ). In addition, metals and metal oxides decorated on CNTs, rGO, and GO as efficient electrocatalysts are employed for uses in the non-enzymatic detections (Dhara et al, 2014 ; Hoa et al, 2015 ; Ngo et al, 2017 ; Jeong et al, 2018 ; Tran et al, 2018 ; Dilmac and Guler, 2020 ). Among these nanocarbons, low-cost GO and rGO attracted more interest because of its large electrochemical active surface area, oxygenic functional groups in complexation with metal ions/metal NPs (redox probes) and in the immobilization of the active antibodies, and good electrical conductivity (Wu et al, 2013 ; Li et al, 2016 ; Sridhar and Park, 2018 ; Wang et al, 2018 ; Barman et al, 2020 ).…”

It is known that although rGO has the higher electric conductivity, GO offers sufficient electrochemical reactivity (Jumpathong et al, 2016 ; Norfun et al, 2017 ).…”

A novel copper (II) ions [Cu(II)]-graphene oxide (GO) nanocomplex-modified screen-printed carbon electrode (SPCE) is successfully developed as a versatile electrochemical platform for construction of sensors without an additionally external redox probe. A simple strategy to prepare the redox GO-modified SPCE is described. Such redox GO based on adsorbed Cu(II) is prepared by incubation of GO-modified SPCE in the Cu(II) solution. This work demonstrates the fabrications of two kinds of electrochemical sensors, i.e., a new label-free electrochemical immunosensor and non-enzymatic sensor for detections of immunoglobulin G (IgG) and glucose, respectively. Our immunosensor based on square-wave voltammetry (SWV) of the redox GO-modified electrode shows the linearity in a dynamic range of 1.0–500 pg.mL−1 with a limit of detection (LOD) of 0.20 pg.mL−1 for the detection of IgG while non-enzymatic sensor reveals two dynamic ranges of 0.10–1.00 mM (sensitivity = 36.31 μA.mM−1.cm−2) and 1.00–12.50 mM (sensitivity = 3.85 μA.mM−1.cm−2) with a LOD value of 0.12 mM. The novel redox Cu(II)-GO composite electrode is a promising candidate for clinical research and diagnosis.
