Surabaya, October 9, 2025 – The Airlangga University Biomedical Engineering Master’s Program held a public lecture entitled “Sensors for Biomedicine: Innovations in Healthcare Technology” with Prof. Dr.-Ing. Lazuardi, M.Si from the University of Riau. This event discussed various medical sensor innovations that are key to the transformation of modern health technology.
In his presentation, Prof. Lazuardi explained that biomedical sensors play an important role in the detection, diagnosis, and monitoring of patient conditions. “Modern sensors are capable of converting biological, chemical, or physical signals into electrical data that can be measured and analyzed in real-time,” he said.
One interesting topic was the development of graphene-based biosensors to detect cancer biomarkers, as well as smart implant sensors that can monitor bone and body tissue conditions wirelessly. This technology is expected to aid in patient recovery after surgery and the management of chronic diseases such as osteoporosis.
In addition, taste sensors that mimic human tongue receptors to evaluate the taste of medicine were also discussed. These sensors are very useful in developing drug formulations that are more acceptable to children and the elderly.
In the applied research section, Prof. Lazuardi presented the results of research related to biosensors for the detection of Hepatitis C using screen-printed carbon electrodes (SPCE) modified with Metal Organic Framework (MOF) materials and gold nanoparticles. Test results showed increased sensitivity in detecting HCV antigens.
Not only that, the research team also developed a sensor for detecting heavy metal cadmium based on Graphene/ZnO-PVA nanocomposites. This sensor has the potential to be a solution for environmental monitoring to prevent exposure to harmful metals that can cause damage to the kidneys, bones, and reproductive system.
According to Prof. Lazuardi, the integration of advanced materials such as graphene, ZnO, and MOF opens up great opportunities for the development of more sensitive, faster, and biocompatible sensors. “Innovation in the field of biomedical sensors is not only for disease diagnosis but also for creating a smarter and more personalized healthcare system,” he added.
The public lecture was attended by students, lecturers, and researchers in the fields of physics and biomedical engineering. The event concluded with an interactive discussion session on the prospects for research collaboration between Airlangga University and Riau University in the development of health sensor technology based on nanomaterials.
