“…Moreover, Ti 3 C 2 T x /BC (3D electrode), [119] and Ti 3 C 2 T x /rGO/LS(3D electrode) [93] exhibited capacitance of 416.0 F/g and 386 F/g respectively which is are very close for some 2D electrode, like MFC/Ti 3 C 2 T x (451 F/g), [106] Mo 1.33 CT z / cellulose (347 F/g). [105] However, PPy/BC@ Ti 3 C 2 T x -based 2D electrode material demonstrated the capacitance at 550 F/g. [78] Although it is considered that the 3D electrode possesses a more specific surface area and a higher porous structure for more electrolyte ion transportation than the stacked 2D electrode, it is difficult to compare the electrochemical performance among 1D, 2D, and 3D electrodes because of approaching various fabrication strategies, different source of cellulose, different concentrations of electrolytes and many others.…”

MXenes, a group of two‐dimensional (2D) metal carbides and nitrides, have emerged as promising electrode materials for supercapacitors. This is primarily attributed to their inherent metal‐like electrical conductivity, layered structure, surface redox reactivity, and superior pseudocapacitance through surface functional groups. Owing to its promising features, this material suffers from low mechanical strength, restacking, and unprecedented oxidation. As a result, balancing the electrochemical performance becomes challenging, eventually impeding its potential applications in lightweight, flexible supercapacitor applications. Recent strategies are centered on lighter and more stable filler materials to tackle these issues. Among these, cellulose is considered one of the most effective renewable materials because of its biocompatibility, thermal stability, high surface area, and mechanical reinforcement. Moreover, nanocellulose is capable of hosting other functional materials on its reactive surfaces, ensuring better ion accessibility, and can be used as an electrolyte separator membrane. This review paper aims to provide a comprehensive overview of recent advances in the fabrication strategy, deterministic parameters for capacitive energy‐storage devices, electrochemical behavior, and the performance of MXene/cellulose‐based electrodes in its three‐dimensional aspect (1D, 2D and 3D) for supercapacitor application. Lastly, this review will outline the challenges and prospects of MXene/cellulose‐based composite electrodes in real‐life supercapacitor applications.

Delayed diagnosis of cancer using conventional diagnostic modalities needs to be addressed to reduce the mortality rate of cancer. Recently, 2D nanomaterial-enabled advanced biosensors have shown potential towards the early diagnosis of cancer. The high surface area, surface functional groups availability, and excellent electrical conductivity of MXene make it the 2D material of choice for the fabrication of advanced electrochemical biosensors for disease diagnostics. MXene-enabled electrochemical aptasensors have shown great promise for the detection of cancer biomarkers with a femtomolar limit of detection. Additionally, the stability, ease of synthesis, good reproducibility, and high specificity offered by MXene-enabled aptasensors hold promise to be the mainstream diagnostic approach. In this review, the design and fabrication of MXene-based electrochemical aptasensors for the detection of cancer biomarkers have been discussed. Besides, various synthetic processes and useful properties of MXenes which can be tuned and optimized easily and efficiently to fabricate sensitive biosensors have been elucidated. Further, futuristic sensing applications along with challenges will be deliberated herein.
