Graphene Nanoplatelets (GNP) as Electrochemical Sensors for Detection of Arsenic Ions (As3+) in Water and Juice Samples

Shahzad, Suniya, Muhammad Balal Arain, and Mustafa Soylak. Journal of Electroanalytical Chemistry (2025): 119413.

This study investigates the use of graphene nanoplatelets (GNP) in the development of a highly sensitive electrochemical sensor for the detection of arsenic (As3+) ions, a significant environmental and health concern. The sensor is based on a nanocomposite of zirconium and nitrogen-doped graphitic carbon nitride (Zr-N-GCN) coupled with GNP, fabricated on a glassy carbon electrode (GCE). The Zr-N-GCN/GNP/GCE electrode shows enhanced electrochemical properties, as confirmed by XRD and FTIR analysis, which demonstrate the successful integration of Zr-N-GCN and GNP. The optimized electrode, prepared by layer-by-layer deposition of 3 μL of GNP, exhibits uniform surface coverage, improving current responsiveness and electrochemical signal consistency.
The electrochemical sensor was evaluated using differential pulse anodic stripping voltammetry (DPASV), achieving a limit of detection (LOD) of 0.31 nM and a linear detection range from 8 to 40 nM. The sensor demonstrated excellent sensitivity (0.605 μA/nM) and reproducibility, with As3+ recovery rates of 93-96% in real juice and water samples. The response time of the sensor was 300 seconds, showcasing its rapid and reliable performance. These findings highlight the potential of GNP-based electrochemical sensors for cost-effective, time-sensitive detection of arsenic contamination in consumables, offering significant advantages for public health monitoring and environmental safety.

Graphene Nanoplatelets (GNP) as Enhancers in Co0.35Zn0.65Fe2-xLaxO4 Composites for Electromagnetic Wave Absorption

Saleem, Muhammad Rizwan, M. Imran Arshad, and Nasir Amin. Ceramics International (2025).

This study investigates the role of graphene nanoplatelets (GNP) in enhancing the properties of Co0.35Zn0.65Fe2-xLaxO4 (CZLF) spinel ferrites, synthesized using the sol-gel auto-combustion (SGAC) method. The GNP were incorporated into the CZLF matrix in varying concentrations (1.25-5 wt%) to create composites, and their electromagnetic, structural, and magnetic properties were extensively characterized. X-ray diffraction (XRD) confirmed the spinel phase, with crystallite sizes ranging from 29.48-58.95 nm. Scanning electron microscopy (SEM) and Raman spectroscopy provided insights into the surface texture and structural integrity of the composites.
The composites demonstrated significant improvements in dielectric and magnetic properties. The real part of permittivity, reflection loss, and AC conductivity for the CZLF/5% GNP composite were measured at 1.090, -3.14 × 10⁻⁴ dB, and -2.40 × 10⁻⁴ S/cm, respectively, at 8 MHz. The saturation magnetization of the CZLF/3.75% GNP composite reached a maximum value of 78.25 emu/g at room temperature. Additionally, the incorporation of GNP reduced DC resistivity and enhanced electromagnetic wave absorption, making these composites excellent candidates for medium-frequency electromagnetic shielding applications.
These findings highlight the potential of GNP as a key component in improving the performance of ferrite-based composites for electromagnetic wave absorption and related applications.

Graphene Nanoplatelets (GNP) as Photothermal Fillers in Bioepoxy-Based Shape Memory Polymer Composites

Raman, Akhila, et al. Materials Research Bulletin (2025): 113619.

This study investigates the use of graphene nanoplatelets (GNP) as photothermal fillers in bioepoxy-based shape memory polymer (SMP) composites, aiming to enhance sustainability and performance for applications in aerospace, robotics, and biomedicine. A bioepoxy resin containing 28% bio-based content served as the matrix, while varying concentrations (0.1-1.5 wt%) of GNPs were incorporated to enable remote actuation under near-infrared (NIR) irradiation at 808 nm. The composites exhibited dual-responsive actuation behavior, triggered by both thermal and NIR stimuli.
Mechanical and thermal property evaluations revealed that the inclusion of GNPs significantly enhanced the fracture toughness of the system by 238.5% compared to the neat bioepoxy. This improvement is attributed to the effective dispersion of GNPs within the bioepoxy matrix and their ability to absorb NIR light, converting it into heat, thus promoting actuation. These composites not only demonstrate exceptional shape memory behavior but also showcase their potential as environmentally friendly, high-performance actuators for next-generation applications.
The preparation of the bioepoxy/GNP nanocomposites involved ultrasonication for dispersion, followed by curing at 150 °C for 15 hours. This work emphasizes the promise of GNP-reinforced bioepoxy composites as a sustainable alternative to petroleum-based systems, marking a significant step in the development of eco-friendly shape memory materials with advanced functional capabilities.
