ABSTRACT

The rapid evolution of biosensor technology has revolutionized early disease detection, offering significant advancements in healthcare monitoring and diagnostic practices. Biosensors, which utilize biological recognition elements coupled with physicochemical transducers, provide a swift and precise detection method for various biomarkers associated with diseases. This paper discusses the types of biosensors, including optical, electrochemical, non-invasive, and miniaturized variants, emphasizing their role in detecting analytes at molecular levels. The paper also highlights the importance of early disease detection, current challenges in the field, and the integration of nanotechnology in biosensor development. Case studies and applications in medical diagnostics are reviewed to illustrate the practical implications of biosensors in improving patient outcomes. Despite the potential, several challenges remain, particularly in the sensitivity and specificity of biosensors for complex disease markers. Continued research and innovation are essential to overcoming these challenges and realizing the full potential of biosensors in early disease detection.
