Summary: Food allergies are abnormal immune responses that occur shortly after exposure to allergenic proteins in food. Treating food allergies is not well understood, so the main prevention method is avoidance. Recent advances in biosensors for on-site detection of food allergens with high selectivity and sensitivity have been explored, along with considerations for quantifying food allergens and global development trends.

Summary: In this study, Zn vacancies were generated on spinel ZnCo2O4 microspheres (V-Zn-ZCO) using the solvothermal synthesis method to enhance their electrochemical performance. The Zn vacancies were quantified using X-ray photoelectron spectroscopy, and the results were supported by Rietveld refinement and energy-dispersive X-ray analysis. The resulting V-Zn-ZCO material had a high specific area and an average pore diameter, enabling faster transport paths and greater surface area for rapid charge transfer. The V-Zn-ZCO electrode exhibited battery-type behavior, achieving a high specific capacity and excellent rate capability, as well as superior cycling stability. Therefore, this study demonstrates that producing cationic vacancies is an effective strategy for improving the electrochemical performance of spinels.
