Researchers at Colorado State University have developed a low-cost, portable device for quickly detecting diseases. The platform uses electrical signals to identify harmful pathogens with high accuracy. It connects to a smartphone app, making testing simple and accessible. Small, reliable, and easy to use; it enables testing in clinics, homes, and field settings.
Early disease detection is critical for effective treatment, but many diagnostic tools are expensive and require laboratory facilities. Techniques like PCR offer high accuracy but are not well suited for using outside of controlled environments. Electrochemical sensing provides a simpler and more portable alternative, though many existing systems lack ease of use and adaptability. This platform addresses these limitations by combining accuracy, affordability, and user-friendly design.
The CREXENS™ platform is a handheld diagnostic device that uses electrochemical impedance spectroscopy (EIS) to detect pathogens by measuring changes in a sample’s electrical properties. It integrates sensors, onboard data processing, and wireless communication with a smartphone app for real-time analysis and display. The system automatically reduces signal noise and adjusts measurement settings to improve performance across different testing conditions.
The device operates across a wide frequency range, enabling precise detection with an error of approximately 2.6%, which is comparable to larger laboratory instruments. Its modular design supports different add-on components for enhanced performance or functionality. With a production cost under $50, the platform combines strong analytical capability with portability, making it suitable for both controlled and real-world environments.
