Electrochemical micronutrient detection using synthetic receptors
A novel electrochemical biosensor using molecularly imprinted polymers (eMIPs) for rapid, noninvasive micronutrient detection from saliva, offering high specificity and sensitivity without enzymes or antibodies.
Overview
This innovative electrochemical biosensor leverages molecularly imprinted polymers (eMIPs) for the rapid, selective detection of micronutrients directly from saliva. By employing electroactive molecularly imprinted polymers, the device provides label-free and reporter-free quantification of nutrients such as vitamins B6, B12, and C through their inherent redox properties. The system's design supports both single-target and multiplexed detection, ensuring high specificity and sensitivity for a range of hydrophilic and hydrophobic micronutrients. This user-friendly platform meets consumer health needs with its noninvasive, cost-effective, and rapid analysis capabilities.
Technical specifications
- Electroactive molecularly imprinted polymers (eMIPs): Enable selective recognition of vitamins and minerals without the need for external redox reporters.
- Disposable test strip with compact reader: Offers instant digital readouts for quick and easy interpretation.
- Adaptability: Compatible with saliva or capillary blood samples for minimally invasive testing.
- Multiplexing capability: Allows simultaneous detection of multiple targets.
- High specificity and sensitivity: Achieved through tailored MIP compositions and electroanalytical approaches.
Technology readiness level
Currently at TRL 3, this technology is in the validation and development phase. Efforts are focused on optimizing MIP formulations and electrochemical response in buffer. Future validation will involve developing a disposable test strip for multiplexed detection, with performance evaluations using spiked samples compared to standard measurements.
