Portable electrochemical sensor device for multivitamin detection
Introducing a non-invasive, cost-effective electrochemical sensor device for real-time multivitamin detection in saliva. This technology offers a rapid alternative to traditional blood tests, supporting personalized healthcare and frequent nutrient monitoring.
Overview
The portable electrochemical sensor device offers a groundbreaking approach to vitamin level assessment by enabling non-invasive, real-time detection and quantification of multivitamins in saliva. Traditional blood tests are invasive and costly, limiting their use for frequent monitoring. This device addresses these limitations by providing an accessible and rapid testing method, aligning with the growing demand for personalized healthcare solutions. Individuals can now track their nutrient levels regularly, facilitating timely dietary adjustments and early detection of deficiencies.
Technical specifications
Key features:
- Utilizes screen-printed electrodes (SPEs) enhanced with nanomaterials like gold nanoparticles and carbon nanostructures for increased electrochemical response.
- Employs differential pulse voltammetry (DPV) or cyclic voltammetry (CV) for precise vitamin concentration measurement in saliva.
- Integrates a microfluidic system for effective saliva collection and filtration, ensuring consistent sample quality.
- Equipped with a microcontroller for signal analysis and result display via LCD screen or smartphone application.
Technology readiness level
Currently at Technology Readiness Level 3, this device is in the early stages of validation and testing. Future steps include clinical validation to confirm the accuracy, reliability, and reproducibility of vitamin measurements.
