Rhizopus stolonifer produces large postharvest losses that account for about 80% of total losses in prepackaged and loose tomato fruits from Rhizopus rot. In this study, we effectively synthesized a Cu- and Sn-codoped mesoporous BaTiO3–G–SiO2 (CuSnBTGS) nanocomposite by utilizing a simple, low-cost self-assembly method for the electrochemical detection of Rhizopus stolonifer fungus; this method does not require a biological or chemical receptor or antibodies. We focused on the microstructure design of CuSnBTGS in combination with Cu and Sn codoping, which is widely regarded as the most efficient way to produce high-performance electrodes. The resultant CuSnBTGS composite exhibited excellent electrochemical characteristics and remarkable performance in the direct detection of Rhizopus stolonifer (bread fungus) levels in contaminated solutions. The chronoamperometric response of the CuSnBTGS composite electrode was linear with Rhizopus stolonifer fungus concentrations in the 50–100 μL range, with a lower detection limit of 0.50 μL. The sensor electrode demonstrated high sensitivity, repeatability, and selectivity. The findings show that Cu- and Sn-codoped mesoporous BTGS is a viable alternative to costly electrode materials, such as gold and platinum, for amperometric sensor applications, demonstrating its applicability in the agricultural and food safety sectors.

“…This composite achieved a higher specific surface area (SSA) than that of the pure BSCF perovskite and exhibited enhanced electrocatalytic oxygen reduction, which was attributed to the ability of MWCNTs to promote electron transfer and provide short-distance transportation between the ionic mass and charge. Chen et al assessed the efficiency of BaTiO 3 /reduced GO (rGO) composites to enhance the performance of screenprinted carbon electrodes, obtaining a high current response when detecting ractopamine, a food additive with antibacterial properties used in the preservation of meat products [34].…”

Although barium titanate (BaTiO3) shows prominent dielectric properties for fabricating electronic devices, its utilization in electrochemical applications is limited. Thus, this study examined the potential of a BaTiO3-based composite in the detection of a food additive, i.e., citric acid. First, a submicron-scale BaTiO3 powder was synthesized using the solution combustion method. Then, a BaTiO3/multiwalled carbon nanotube (MWCNT) composite was hydrothermally synthesized at BaTiO3:MWCNT mass ratios of 1:1 and 2:1. This composite was used as a working electrode in a nonenzymatic sensor to evaluate its electrocatalytic activity. Cyclic voltammetric measurements revealed that the BaTiO3/MWCNT composite (2:1) exhibited the highest electrocatalytic activity. Reduction reactions were observed at applied voltages of approximately 0.02 and −0.67 V, whereas oxidation reactions were detected at −0.65 and 0.47 V. With acceptable sensitivity, decent selectivity, and fair stability, the BaTiO3/MWCNT composite (2:1) showed good potential for citric acid detection.
