Electrochemical biosensors are pivotal in modern diagnostics, integrating biological recognition elements with electrochemical transducers to detect analytes in bodily fluids with high sensitivity and specificity. These devices have seen significant advancements, allowing them to be miniaturized for portable, wearable, and implantable applications, making point–of–care diagnostics more accessible. This review article delves into the various types of electrochemical biosensors, their integration into digital health systems, and the challenges and future directions in this rapidly evolving field.
Electrochemical biosensors operate by using a biological recognition element, such as enzymes, antibodies, or nucleic acids, that interacts with the target analyte. This interaction produces an electrochemical signal measured by the transducer. These sensors are crucial for detecting various biomarkers in bodily fluids like blood, saliva, and tears, offering rapid and accurate diagnostics.
The integration of these biosensors into digital health systems involves developing devices that are not only accurate and reliable but also user-friendly and cost-effective. Key applications include:
The future of electrochemical biosensors lies in enhancing their performance and integrating them more seamlessly into everyday healthcare. This involves:
Electrochemical biosensors represent a transformative technology in personalized medicine, offering accessible and efficient diagnostic solutions. Their continued development and integration into healthcare systems promise significant advancements in disease management and patient care. As we overcome the current challenges and explore new innovations, the potential of these devices will be fully realized, ushering in a new era of digital health.
