Abstract

A simple and economical approach to produce graphene nanosheets (GNSs) in quantity based on the thermal expansion of graphite oxide (GO) powder has been developed, and the as-prepared GNS was further used for the detection of different trace heavy metal ions including Cu²⁺, Pb²⁺, and Cd²⁺. The few-layer GNSs with defects and residual –OH groups were shown to be particularly well suited for the determination of metal ions in the liquid phase using an electrochemical method, in which a remarkably low detection limit of 10⁻¹¹M for Pb²⁺ was achieved. The high-yield production technique of GNSs combined with the high sensitivity for the detection of metal ions could promote the development of the industrial manufacture of graphene-based nanosensors.

Sensitive and selective Cu<sup>2+</sup> detection via surface plasmon resonance using ionophore decorated nanocrystalline cellulose-graphene oxide thin film
2024, Sensors and Actuators A: Physical
In this work, highly sensitive and selective surface plasmon resonance (SPR) sensor has been developed using nanocrystalline cellulose-graphene oxide-ionophore (NCC-GO-ionophore) for copper ion (Cu²⁺) detection. By incorporating SPR with nanocrystalline cellulose-graphene oxide-ionophore (NCC-GO-ionophore) thin film, Cu²⁺ was able to be detected as low as 0.001 ppm until 0.1 ppm. Moreover, the results show that the NCC-GO-ionophore thin film has good sensitivity towards Cu²⁺ with sensitivity value of 59.9150° ppm⁻¹ from 0.001 to 0.01 ppm and 2.2261° ppm⁻¹ from 0.01 to 0.1 ppm. Besides that, the developed sensor also shows high affinity towards Cu²⁺ compared to other metal ions. Using the Langmuir isotherm model, the binding affinity constant, K was calculated i.e., 6.881 × 10³ M⁻¹. Furthermore, the ability of the sensor to detect Cu²⁺ in spiked river water sample was also investigated where Cu²⁺ as low as 0.5 until 100 ppm can be determined. This result shows that the sensor has high sensitivity and selectivity towards Cu²⁺ detection.
Development of semiconductor based heavy metal ion sensors for water analysis: A review
2021, Sensors and Actuators, A: Physical
Heavy metal ions are highly toxic, carcinogens, and non-biodegradable in nature and pollute most water resources that lead to severe health-related issues. It is essential to develop highly sensitive, selective, rapid, and accurate approaches for their detection in water. Semiconducting devices and materials with micro and nanostructures have been featured with fast response time, low power, high sensitivity, low detection limit. This review concisely introduces the recent trends in heavy metal ion sensing with semiconductor devices, including ion-sensitive field-effect transistors (ISFETs) and AlGaN/GaN high electron mobility transistors (HEMTs) and semiconductor materials like graphene, two-dimensional metal dichalcogenides, decorated with different nanoparticles with appropriate functionalization.
Monolayered graphene oxide as a protective barrier on polycrystalline copper substrate against thermal oxidation for a long duration
2021, Journal of Electroanalytical Chemistry
Citation Excerpt :
Graphene or GO monolayers (thickness < 1 nm) are barely detectable by SEM. Alternatively, they can be detected by optical microscopy [36], AFM [37], or Raman [38]. Fig. 4a shows an optical micrograph of coated pristine copper foil.
This work aimed to describe an innovative and economical method for coating copper with Graphene Oxide (GO) via dip coating and a study of the resulting barrier properties against oxidation. The thickness GO was found as an optimized thin film in the nanometer (0.5–0.7 nm) range. The kinetics of thermal oxidation at low temperature (160 °C) is followed by an original procedure based on Raman spectroscopy. This approach permitted an unambiguous identification of cuprous oxide (Cu₂O) on micron size regions and probed the measurement of the thin oxidized layer down to the nm scale. The findings showed that a monolayer of GO does not substantially alter oxidation kinetics at short times (~1 h). Furthermore, it was found that GO film exhibited highly improved thermal oxidation stabilities due to remarkable gas barrier property. It remained an excellent candidate for passivation barrier and resistance to oxidation of copper since GO film significantly reduced the further propagation of the Cu₂O layer at a long timescale (days) under the barrier film.
Graphene oxide and graphene oxide functionalized with silver nanoparticles as adsorbents of phosphates in waters. A comparative study
2020, Science of the Total Environment
Phosphate removal is an important factor that must be taken into account in eutrophized waters. For this reason, many studies on different ways of removing phosphates from water have been published nowadays. In this work, a comparative study between the use of graphene oxide (GO) and graphene oxide functionalized with silver nanoparticles (GO@AgNPs) as adsorbents to remove phosphates from water samples has been carried out. Experimental conditions, including the pH, adsorbent dose, contact time and temperature, have been analyzed to achieve the highest adsorption efficiency. Although both adsorbents can be considered suitable for removing phosphates from aqueous solutions, GO@AgNPs provided a maximum removal efficiency of 100%, reaching the equilibrium conditions instantaneously under straightforward experimental conditions. Moreover, a much lower adsorbent dose was necessary than with graphene oxide. When GO was used, the maximum removal efficiency was 75%, 9 min were necessary to reach the equilibrium conditions and 20 mg of adsorbent were needed. Both adsorbents can be regenerated in an acid medium, giving recovery percentages of 98% and 80% for GO and GO@AgNPs respectively, which allows them to be recycled and used again.
Heavy metal and metalloid electrochemical detection by composite nanostructures
2019, Advanced Nanostructures for Environmental Health: Micro and Nano Technologies
The purpose of this chapter is to deliver an overview of the available composite nanostructure-based materials used as electrode materials for the electrochemical detection of heavy metals and metalloids. The electrode performances (sensitivity, reproducibility, stability, selectivity, fast response, efficiency in the multiplexed detection, and onsite detection ability) are presented. Due to their special properties and characteristics, the carbon nanocomposite-based electrodes are shown as the most common sensing platforms for heavy metal and metalloid detection. Thus, in four subchapters, the advantages of using graphite, mesoporous carbon, carbon nanotubes (CNTs), and graphene (G) nanocomposites as electrode materials are shown. Among the carbon nanocomposite-based electrode materials, the G-based composite, with different architectures and morphologies, exhibits excellent performances (such as sensitivity, detection limit, selectivity, linear range of detection, stability, repeatability, etc.) for the detection of heavy metals and metalloids. Toxic metal and metalloid electrochemical detection at composite nanostructure-based electrodes facilitates the miniaturization (which leads to sample and reagent volume reduction, lower operational costs, portability, etc.) and automatization of the electrochemical sensors. Moreover, their application field can be extended from environment monitoring to the clinical, safety, defense, and security fields.
Label-free paper-based electrochemical impedance immunosensor for human interferon gamma detection
2019, Sensors and Actuators, B: Chemical
Human interferon-gamma (IFN-γ) plays an important role in diagnosis of tuberculosis susceptibility, which is one of the crucial health problems worldwide. Here, a novel platform of paper-based microfluidic device coupled with label-free electrochemical impedance immunosensor was developed for sensitive detection of human IFN-γ. Polyaniline (PANI) was deposited on a graphene (G) screen-printed paper electrode by using cyclic voltammetry. The modified electrode provides high electrochemical conductivity and surface area for antibody immobilization, which significantly enhances the sensitivity. A linear relationship between impedance and logarithmic concentrations of human IFN-γ was found in a range of 5―1000 pg mL^―1 with a detection limit (LOD) of 3.4 pg mL^―1. Interestingly, the PANI-G modified electrodes display 31-fold higher sensitivity compared to PANI-modified electrodes. The PANI-G modified electrode was successfully applied to the determination of human IFN-γ in human serum with a good reproducibility. Moreover, the system offers several advantages including low cost, low sample volume requirement, disposability, and rapid analysis relative to traditional methods, allowing the platform to be used as an alternative tool for human IFN-γ screening.
