Summary: Spherical MnCoOx and MnCoOx-multi-walled carbon nanotubes (MnCoOx-MWCNTs) composites were synthesized and used as electrode materials for supercapacitors. The properties of different MnCoOx samples with various Co/Mn molar ratios and MnCoOx-MWCNTs samples with different MWCNTs qualities were evaluated using various electrochemical test methods. The results showed that the MnCoOx-MWCNTs composite with a Co/Mn molar ratio of 1:1 and 0.1 g MWCNTs exhibited a high discharge capacitance of 930.00 F g(-1) at a current density of 1.0 A g(-1). The specific capacitance retention rate of the optimal MnCoOx-MWCNTs composite remained at 88.2% after 5000 cycles at a current density of 8.0 A g(-1). Therefore, the MnCoOx-MWCNTs composite shows great potential as an electrode material for supercapacitors.

Summary: In this article, the latest developments in biosensors for cancer cell detection are highlighted. Electrochemical (EC) biosensors provide advantages such as high sensitivity, selectivity, rapid analysis, portability, and low-cost. Different types of biosensors, including immunosensors, aptasensors, cytosensors, electrochemiluminescence (ECL), and photo-electrochemical (PEC) sensors, can be classified. The significance of EC biosensors lies in their ability to detect various biomolecules in the human body, including cholesterol, glucose, lactate, uric acid, DNA, blood ketones, hemoglobin, and others. Recently, EC biosensors have been developed using electrocatalytic materials such as Ag2S, BPene, HCNT, CDs/CoOOH, Cu2O, PDs, MnO2, graphene derivatives, and Au-NPs. These biosensors have shown potential for detecting cancer cells with a limit of detection (LOD) of 1 cell/mL. However, more real samples need to be tested to verify the accuracy and reliability of these EC biosensors in measuring cancer cells in blood and salivary samples.
