Melphalan (Mel) is a potent alkylating agent utilized in chemotherapy treatments for a diverse range of malignancies. The need for its accurate and timely detection in pharmaceutical preparations and biological samples is paramount to ensure optimized therapeutic efficacy and to monitor treatment progression. To address this critical need, our study introduced a cutting-edge electrochemical sensor. This device boasts a uniquely modified electrode crafted from graphitic carbon nitride (g-C 3 N 4 ), decorated with activated nanodiamonds (ND-COOH) and molybdenum diselenide (MoSe 2 ), and specifically designed to detect Mel with unparalleled precision. Our rigorous testing employed advanced techniques such as cyclic voltammetry and differential pulse voltammetry. The outcomes were promising; the sensor consistently exhibited a linear response in the range of 0.5 to 12.5 μM. Even more impressively, the detection threshold was as low as 0.03 μM, highlighting its sensitivity. To further enhance our understanding of Mel's biological interactions, we turned to molecular docking studies. These studies primarily focused on Mel's interaction dynamics with the cellular tumor antigen P53, revealing a binding affinity of −5.0 kcal/mol. A fascinating observation was made when Mel was covalently conjugated with nanodiamond-COOH (ND-COOH). This conjugation resulted in a binding affinity that surged to −10.9 kcal/mol, clearly underscoring our sensor's superior detection capabilities. This observation also reinforced the wisdom behind incorporating ND-COOH in our electrode design. In conclusion, our sensor not only stands out in terms of sensitivity but also excels in selectivity and accuracy. By bridging electrochemical sensing with computational insights, our study illuminates Mel's intricate behavior, driving advancements in sensor technology and potentially revolutionizing cancer therapeutic strategies.

“…[15,104] Battery-type supercapacitors typically exhibit distinctive characteristics, including discharging at a relatively stable voltage with a gradual linear decline until it reaches the end of its storage capacity, at which point there is a rapid decrease in the supplied voltage. [105] While there is less research into battery type hybrid technology than other SC types, there is evidence that these hybrids might be able to close the supercapacitor-batteries gap. [103,106] Working mechanisms of different types of SCs is shown in Figure 7.…”

Supercapacitors (SCs) have attracted significant attention in the realm of energy storage devices due to their exceptional features, such as enhanced charge storage capacity, fast charge‐discharge rates, and high power density. The emergence of cost‐effective and highly productive SCs is a topic of interest among industrial and scientific communities. Ferrites with a perovskite crystal structure are often considered excellent electrode materials due to their intrinsic properties, affordability, low environmental impact, and widespread availability. An in‐depth investigation of perovskite ferrites in the context of SCs is necessary to advance the understanding of these materials. The techniques used in the synthesis of ABO3‐type perovskite bismuth ferrite materials are comprehensively reviewed in this review. The review starts by analyzing various types of SCs classified based on their electrode materials. The review provides a comprehensive understanding of the design and functionality of these devices, serving as an important source of inspiration for new methods of synthesis and fabrication methodologies that aim to produce environmentally friendly SCs.

“…3−7 The improve-ment of novel capacitive materials with high energy, power, and cycle life densities for promising practical uses in highpower electronics and compact electronics is now a major problem for SCs. 8 Redox reactions on electrode materials (typically of metal oxides, sulfides, and selenides) with electrolyte ions can significantly increase the specific capacitance related to the carbon-based material. Accordingly, metal oxide-based symmetric SCs were designed, which showed higher capacitance than the electrical double-layer capacitors, but they are limited by the cell voltage.…”

Development of metal sulfide nanostructures using simple synthesis methods, enhanced electrochemical properties, and superior redox activity are highly desirable for the scalable fabrication of hybrid supercapacitors (HSCs). In this study, we presented a unique nanonetwork architectured cobalt sulfide on Ni-foam (Co x S y @NF) using an in situ wet-chemical method at lowtemperature. The as-grown hierarchical Co x S y nanostructures on the nickel skeleton enable strong adhesion with highly conductive, fast redox reactions, and superior electrochemical energy storage. The Co x S y nanonetwork exhibited a remarkable specific capacity of 838 C/g (2148 F/g), excellent rate performance of 66.8%, and cyclic stability of 97% over 6000 GCD cycles. The elevated redox properties of Co x S y nanostructures can be achieved due to the improved transport properties. The hierarchical architectured Co x S y @ NF was further used as a redox-type electrode for HSCs. The fabricated hybrid Co x S y //AC SC device exhibited a high energy density of 28.5 W h/kg with a device voltage of 1.55 V and a capacitance retention of 96% over 6000 cycles. The outstanding electrochemical properties and high mechanical integrity of the Co x S y nanonetwork can be used as advanced electrode material for scalable energy storage devices.
