“…These results demonstrate that the NCT 1/GCE electrode can be used for the detection of H 2 O 2 and could be useful for physiological and pathological studies. 1 , 5 , 23 Scheme 2 describes H 2 O 2 release from RAW 267.4 living cells detected by the developed electrochemical sensor. This illuminates that the NCT 1/GCE NRs provide a promising platform to monitor H 2 O 2 .…”

In this study, we report about the preparation of nickel cobalt telluride nanorods (NiCoTe NRs) by the hydrothermal method using ascorbic acid and cetyltrimethylammonium bromide as reducing agents. The NiCoTe NRs (NCT 1 NRs) were characterized through use of different methods. The nonlinear optical measurements were carried out using Z-scan techniques. The results give the nonlinear absorption that arises from the combined two photon absorption and free carrier absorption. NCT 1 has an excellent electrocatalytic activity toward hydrogen peroxide with a sensitivity of 3464 μA mM –1 cm –2 , a wide linear range of 0.002–1835 μM, and the lower detection limit of 0.02 μM, and the prepared electrode was strong in sensing in vivo H 2 O 2 free from raw 264.7 cells. Therefore, the binary transition metal chalcogenide based nanostructures have promising potential in live cell biosensing applications.

“…In addition to the advantages described above, Zhang et al [205] Several other research groups have employed the idea of combining more than one metal to fabricate electrochemical sensors for the detection of H2O2 in living cells [214,215]. For example, Mani et al [216] obtained an extraordinarily low LOD in the nanomolar range by modifying nickel cobalt sulfide/cobalt sulfide nanostructure arrays (NiCo2S4@CoS2 NAs) with a carbon cloth (CC). The NiCo2S4@CoS2 NAs provided a 3D hierarchical network with a highly porous structure and excellent conductive properties.…”

Reactive oxygen species (ROS) have been found in plants, mammals, and natural environmental processes. The presence of ROS in mammals has been linked to the development of severe diseases, such as diabetes, cancer, tumors, and several neurodegenerative conditions. The most common ROS involved in human health are superoxide (O2•−), hydrogen peroxide (H2O2), and hydroxyl radicals (•OH). Organic and inorganic molecules have been integrated with various methods to detect and monitor ROS for understanding the effect of their presence and concentration on diseases caused by oxidative stress. Among several techniques, fluorescence and electrochemical methods have been recently developed and employed for the detection of ROS. This literature review intends to critically discuss the development of these techniques to date, as well as their application for in vitro and in vivo ROS detection regarding free-radical-related diseases. Moreover, important insights into and further steps for using fluorescence and electrochemical methods in the detection of ROS are presented.

“…Electrochemical sensors made with this material but not necessarily used to investigate living cells were reviewed elsewhere [85]. Three other TMDs (WS 2 [72], CoS 2 [80] and Mo 0.75 W 0.25 S 2 [83]) and an MXene (Ti 3 C 2 [81]) were also used to make electrochemical sensors to investigate living cells. It is difficult to say if one of these novel 2D materials is better for building electrochemical sensors than the other because the number of electrochemical sensors made with them is still too small and the devices are built in very different manners (e.g.…”

2D materials in electrochemical sensors for in vitro or in vivo use

Individual cells and cell populations are at the present time investigated with a myriad of analytical tools. While most of them are commercially available, some of these analytical tools are just emerging from research laboratories and are in the developmental phase. Electrochemical sensors which allow the monitoring of low molecular weight compounds released (and / or uptaken) by cells are among these emerging tools. Such sensors are increasingly built using 2D materials (e.g. graphene-based materials, transition metal dichalcogenides, etc.) with the aim of conferring better analytical performances to these devices. The present work critically reviews studies published during the last 10 years describing electrochemical sensors made with 2D materials and exploited to monitor small compounds (e.g. H 2 O 2 , •NO, glucose, etc.) in living biological systems. It also discusses the very few 2D material-based electrochemical sensors which are wearable or usable in vivo. Finally, the present work includes a specific section about 2D material biocompatibility, a fundamental requirement for 2D material-based sensor applications in vitro and in vivo. As such, the review provides a critical view on the state of the art of electrochemical sensors made with 2D materials and used at cellular level and it evaluates the possibility that such sensors will be used on / in the human body on a wider scale.
