Electrochemical Spore Detection

The 76th Annual Meeting of the International Society of Electrochemistry will take place from 7th to 12th September in Mainz, Germany. The focus of this meeting is electrochemistry - From Basic Insights to Sustainable Technologies.
Aleksandar Mijajlović from the Faculty of Chemistry, University of Belgrade will represent the MOBILES project with an poster presentation.

As part of our ongoing research into food safety and innovative detection technologies, Aleksandar Mijajlović will be presenting a poster titled: “Electrochemical Spore Detection: A Novel La₂O₃/rGO-Based Aptasensor for Rapid and Sensitive Biosensing” at 76th Annual Meeting of the International Society of Electrochemistry 7.-12.9.2025 in Mainz, Germany.

This work focuses on the detection of Bacillus cereus, a common foodborne bacterium that can cause serious illness. What makes B. cereus particularly challenging is its ability to form spores that are highly resistant to heat and other harsh conditions—making early and reliable detection essential for protecting public health.
The team has developed a new type of biosensor using advanced nanomaterials—combining lanthanum oxide (La₂O₃) with reduced graphene oxide (rGO). This sensor is designed to quickly and accurately detect bacterial spores, even in real-world samples.
Early results are promising: the sensor is not only sensitive and fast, but also easy to use, offering potential for applications in food safety monitoring and public health protection.

This exciting development is part of our broader mission to bring cutting-edge science closer to practical solutions in everyday life.
