REAL-TIME MONITORING OF PHYSIOLOGICAL CHANGES USING CNT-BASED NANOSENSORS

Abstract

The integration of carbon nanotube technology into physiological monitoring represents a transformative advancement in healthcare diagnostics and patient care. This research investigates the development and application of CNT-based nanosensors for continuous, real-time monitoring of critical physiological parameters including glucose levels, cardiac biomarkers, neurological signals, and metabolic indicators. Traditional monitoring systems rely on invasive procedures, intermittent sampling, and bulky equipment that limits patient mobility and comfort. CNT nanosensors address these limitations through their exceptional electrical conductivity, biocompatibility, miniaturization potential, and sensitivity to molecular interactions. Our comprehensive analysis examines sensor design principles, fabrication techniques, signal transduction mechanisms, and clinical applications across multiple physiological domains. The research demonstrates that CNT-based sensors achieve detection sensitivities in the nanomolar range while maintaining biocompatibility suitable for extended wearable and implantable applications. Integration with wireless communication systems enables continuous data streaming to healthcare providers, facilitating early intervention and personalized treatment optimization. This work establishes both the technical foundations and practical pathways for translating CNT nanosensor technology from laboratory research into clinical reality, addressing critical gaps in continuous patient monitoring capabilities.
