Summary: In this study, we demonstrated that the direct intercalation of alkali-metal cations is not necessary for the redox reaction of Prussian blue. Passivation of Prussian blue thin films with monolayer graphene preserved its electrochemical activity and enhanced its stability. We also showed the potential of a transparent graphene electrode as an efficient hydrogen peroxide transducer.

Summary: This paper presents an electrochemical sensor for monitoring the shelf life of anchovy. The sensor addresses critical user needs in food applications including fast response, high reproducibility, and ease of use. It has been calibrated against seven specific biogenic amines associated with anchovy spoilage, showing potential in both BAs quantification and spoilage monitoring. The sensor's responses closely followed sample evolution over time and compared well with LC-UV results. Further developments are needed to establish a standard method for industrial application.

Summary: This research work presents a green, sensitive, selective, and simple electrochemical strategy for the detection of ciprofloxacin in various samples. The carbon paste electrode was modified using reduced graphene oxide and clay nanocomposite, which resulted in improved conductivity and surface area. The electrochemical performance of the modified electrode was evaluated and found to have excellent sensitivity towards ciprofloxacin. Under optimized conditions, the electro-analytical response showed a linear relationship with ciprofloxacin concentration in the range of 0.03-2.0-50.0 μM, with a lower detection limit and high sensitivity. Additionally, the modified electrode was successfully applied to detect ciprofloxacin in drugs, wastewater, and urine samples, with satisfactory recoveries.
