“…Additionally, N doping can remarkably improve the conductivity [41] and can enhance the biocompatibility of graphene [42]. Accordingly, N-doped graphene or its derivatives are used in electromagnetic wave absorption [43], electrochemical sensors [44], biosensors [45,46], gas sensors [47], electrocatalysts [48,49], solar cells [50], supercapacitors [51], energy conversion [52], and energy storage [53].…”

Today, resistance gas sensors which are mainly realized from metal oxides are among the most used sensing devices. However, generally, their sensing temperature is high and other materials with a lower operating temperature can be an alternative to them. Graphene and its derivatives with a 2D structure are among the most encouraging materials for gas-sensing purposes, because a 2D lattice with high surface area can maximize the interaction between the surface and gas, and a small variation in the carrier concentration of graphene can cause a notable modulation of electrical conductivity in graphene. However, they show weak sensing performance in pristine form. Hence, doping, and in particular N doping, can be one of the most promising strategies to enhance the gas-sensing features of graphene-based sensors. Herein, we discuss the gas-sensing properties of N-doped graphene and its derivatives. N doping can induce a band gap inside of graphene, generate defects, and enhance the conductivity of graphene, all factors which are beneficial for sensing studies. Additionally, not only is experimental research reviewed in this review paper, but theoretical works about N-doped graphene are also discussed.

“…In this context, zinc oxide nanoparticles (ZnO-NP) [8,9], having excellent electronic, physicochemical, catalytic, and optic properties [1] allow their use in environmental remediation/protection, supercapacitor, and (bio)sensor applications [10]. The literature survey describes the use of ZnO-NP for the electrochemical detection of various biomolecules such as glucose, urea, dopamine, ascorbic acid, uric acid [1], formaldehyde [11], sulfamethoxazole [12], non-enzymatic H 2 O 2 [1,13], phenolic derivatives, hydrazine [1] or heavy metals [1,14]. Along with its remarkable properties (low dielectric constant, high luminous transmittance, good physicochemical stability, high excitation binding energy, electron mobility, and biocompatibility) ZnO exhibits also low toxicity and low price [1,10].…”

ZnO nanoparticles (ZnO‐NP) were prepared by a facile precipitation technique using di‐isopropyl amine as precipitating agent. The morpho‐structure and porosity of the as‐prepared nano‐powder were investigated by FT‐IR analysis, X‐ray diffraction (XRD), scanning electron microscopy (SEM), and BET analysis. By drop‐casting, a composite film was deposited to obtain ZnO‐NP‐Nafion/GCE modified electrode. The modified electrode was investigated by cyclic voltammetry, electrochemical impedance spectroscopy, and square wave anodic stripping voltammetry (SWASV) for the detection of Pb2+, Cd2+, Cu2+, and Fe3+, and it was successfully applied for the detection of Pb2+ and Cu2+ in real water samples.
