“…These nanofibers were obtained by calcinating electrospun rGO)/Mn(Ac) 2 /Co(Ac) 2 /polyvinyl pyrrolidone composite fibers at a high temperature. The biosensor exhibited excellent activity toward glucose oxidation in real blood serum samples . Electrochemistry‐based DNA biosensors have recently developed interest as they are suitable for miniaturization and compatible with advanced microfabrication schemes.…”

Development of next-generation sensor devices is gaining tremendous attention in both academia and industry because of their broad applications in manufacturing processes, food and environment control, medicine, disease diagnostics, security and defense, aerospace, and so forth. Current challenges include the development of low-cost, ultrahigh, and user-friendly sensors, which have high selectivity, fast response and recovery times, and small dimensions. The critical demands of these new sensors are typically associated with advanced nanoscale sensing materials. Among them, graphene and its derivatives have demonstrated the ideal properties to overcome these challenges and have merged as one of the most popular sensing platforms for diverse applications. A broad range of graphene assemblies with different architectures, morphologies, and scales (from nano-, micro-, to macrosize) have been explored in recent years for designing new high-performing sensing devices. Herein, this study presents and discusses recent advances in synthesis strategies of assembled graphene-based superstructures of 1D, 2D, and 3D macroscopic shapes in the forms of fibers, thin films, and foams/aerogels. The fabricated state-of-the-art applications of these materials in gas and vapor, biomedical, piezoresistive strain and pressure, heavy metal ion, and temperature sensors are also systematically reviewed and discussed, and their sensing performance is compared.

“…Both, functionalized carbon nanotubes (CNT) and graphene oxide (GO), are known to interact with metals and oxides [18][19][20][21][22][23][24][25]. In the last case, the number of examples is increasing exponentially in several applications like energy storage and catalysis [18][19][20][21][22][23][24][25][26][27].…”

“…Among the materials developed for the Cd detection, the spinel metal oxides are the promising materials due to high earth abundance, low cost and environmentally friendly 27–29 . Hence, MnCo 2 O 4 has been accepted as an alternative electrode material for the Cd sensor due to its excellent conductivity and tunable structural features 30, 31 . MnCo 2 O 4 lies on the normal spinel family that consists of Mn 2+ ions in tetrahedral sites, Co 3+ ions in the octahedral sites and O −2 ions tend to coordinate both positions to frame the face centred cubic structure 32 .…”

To utilize the maximum activity of nanomaterials, it was specifically synthesized by appropriate physicochemical properties. In that aspect, we have described the synthesis of porous MnCo2O4 by simple chemical route and applied for the selective detection of cadmium (Cd (II)). The as-prepared porous MnCo2O4 was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer–Emmett–Teller (BET) adsorption isotherm, X-ray diffraction pattern analysis (XRD), Fourier transform infra-red spectroscopy (FT-IR), energy dispersive X-ray (EDX) and electrochemical techniques. The porous MnCo2O4 exhibited an excellent electrochemical behaviour and good analytical response towards the determination of Cd (II). Those analytical factors such as pH, deposition potential and deposition time are optimized by using differential pulse anodic stripping voltammetry (DPASV). A wide linear concentration range from 2.3 to 120 µg L−1, limit of detection (LOD) of 0.72 µg L−1 and the limit of quantification (LOQ) of 0.91 µg L−1 were achieved for determination of Cd (II). The selectivity of the developed sensor was explored in the presence of co-interfering ions. Also our sensor exhibits a good stability, reproducibility and repeatability. In addition, the practicability of proposed sensor was evaluated for the detection of Cd (II) in real water samples.
