2025 - Stage I – Selection and characterization of nanostructured active materials and matrices for the design of stochastic sensors, design of screen-printed stochastic sensors and platforms, and conducting preliminary tests for sensors
Progress Summary
In the first phase of the project, all objectives were achieved. Electrochemical sensors are versatile and inexpensive and can detect a wide range of biomarkers. Stochastic sensors were based on carbon-based matrices, as these materials offer remarkable electrical and thermal conductivity, a fast electron transfer rate, and low charge transfer resistance, all of which improve the sensitivity and response time of sensors in electrochemical detection. The best nanostructured materials were selected and characterized by photoelectron X-ray spectroscopy. Stochastic sensors were constructed and characterized electrochemically. Interleukin 6 was chosen as an indicator of colon cancer, and its specific signature was determined using the calibration curve.
