摘要

应用科学对检测生物分子（如多巴胺（DA）、抗坏血酸（AA）和尿酸（UA））的需求日益增长，这推动了对创新材料的需求，以增强医疗保健诊断。本研究介绍了铋掺杂的CoCr2O4 （BCC）纳米晶体，通过简单的燃烧方法合成，用于电化学生物传感和超级电容器的应用。bcc修饰的碳糊电极多巴胺检测灵敏度提高64%，检测限低至0.25µM，对尿酸具有良好的选择性，同时在10个周期内保持86.87%的稳定性。对于超级电容器，BCC纳米复合材料具有309.24F/g（循环伏安，CV）和338.88F/g（恒流充放电，GCD）的高比电容，能量密度为67.77 Wh/kg，循环5000次后容量保持率为86.12%。这些发现突出了BCC在医疗诊断和能量存储方面的多功能性。

Bismuth doped spinel CoCr2O4 nanocrystals for dual application on supercapacitor and dopamine detection

The increasing demand in applied sciences for the detection of biological molecules such as dopamine (DA), ascorbic acid (AA), and uric acid (UA) drives the need for innovative materials to enhance healthcare diagnostics. This study introduces bismuth-doped CoCr₂O₄ (BCC) nanocrystals, synthesized via a simple combustion method, for electrochemical biosensing and supercapacitor applications. A BCC-modified carbon paste electrode enhances dopamine detection sensitivity by 64 %, achieving a low detection limit of 0.25 µM and excellent selectivity against uric acid, while maintaining 86.87 % stability over 10 cycles. For supercapacitors, BCC nanocomposites demonstrate a high specific capacitance of 309.24F/g (cyclic voltammetry, CV) and 338.88F/g (galvanostatic charge/discharge, GCD), with an energy density of 67.77 Wh/kg and 86.12 % capacity retention after 5000 cycles. These findings highlight BCC’s versatility for both healthcare diagnostics and energy storage.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
