“…Furthermore, an obvious decrease in current response was observed in the presence of catalase, which confirmed that the detective H 2 O 2 was secreted only from the living HeLa cells. These results were consistent with the previous reports [11,35,57,58]. It were of great significance for the therapeutic strategies development and cancer chemoprevention.…”

Prussian blue nanoparticles (PBNPs) have peroxidase‐like activity for H2O2. However, PB alone have poor electrochemical performances. Herein, a strategy was proposed by direct in‐situ growth PBNPs onto gold nanowires (AuNWs) surface to obtain the peroxidase‐like activity with about 4.05 times higher than that of PBNPs alone. PBNPs@AuNWs was employed to construct a non ‐ enzymatic electrochemical H2O2 sensor with the detection limit of 5.3×10−9 mol/L (S/N=3). The sensor was successfully used to detect H2O2 in human serum samples or secreted from living HeLa cells. It may be a competitive candidate for H2O2 assaying in biological samples or cellular investigation.

“…These studies suggest a novel direction combining MXenes with other novel nanomaterials to develop ultrasensitive electrochemical biosensors. In addition to studies in which biomolecules such as enzymes and nucleic acids were introduced as sensing probes, studies on the development of electrochemical biosensors without biomolecules are also in progress, including non-enzymatic electrochemical biosensors based on MXenes [66,67].…”

The development of advanced biosensors with high sensitivity and selectivity is one of the most demanded concerns in the field of biosensors. To meet this requirement, up until now, numerous nanomaterials have been introduced to develop biosensors for achieving high sensitivity and selectivity. Among the latest nanomaterials attracting attention, MXene is one of the best materials for the development of biosensors because of its various superior properties. MXenes are two-dimensional inorganic compounds with few atomic layers that possess excellent characteristics including high conductivity and superior fluorescent, optical, and plasmonic properties. In this review, advanced biosensors developed on the basis of the MXene nanocomposite are discussed with the selective overview of recently reported studies. For this, introduction of the MXene including the definition, synthesis methods, and its properties are discussed. Next, MXene-based electrochemical biosensors and MXene-based fluorescent/optical biosensors are provided, which are developed on the basis of the exceptional properties of the MXene nanocomposite. This review will suggest the direction for use of the Mxene nanocomposite to develop advanced biosensors with high sensitivity and selectivity.

“…22,23 Enzymatic sensors that are prepared by immobilizing the enzymes on the electrode surfaces monitor the detection target using the interaction between the target and the enzyme. 24,25 However, the preparation procedure for enzymatic sensors is complicated, and enzymes cannot enable the perfect long-term stability of the sensor. To overcome these shortcomings, various enzyme-free electrochemical sensors have attracted significant attention for the electrochemical detection of H 2 O 2 .…”
