Sensor devices for detecting biomarkers associated with particular diseases, such as diabetes and tuberculosis, have been developed in the field of diagnostics; however, currently available devices suffer from drawbacks that detract from their use in non-invasive diagnostic methods, such as poor detection limits and/or unreliable responses. Such devices also require assembly methods or complex components/configurations that result in high manufacturing costs and the inability to produce single-use devices. There exists a need in the art of diagnostics for new devices that exhibit improved detection limits, more reliable responses during use, and that can be made in a cost-effective manner, particularly for point-of-use care.
Researchers at the University of Nevada, Reno have developed a novel paper-based electrochemical sensor that is designed to detect biomarkers associated with infectious diseases, such as tuberculosis. This device can be made with low-cost materials and can be fabricated efficiently and thus avoid the complex fabrication methods and high manufacturing costs associated with current electrochemical sensor devices, particularly those that have been developed for tuberculosis biomarker detection.
