Abstract

Point-of-care (POC) bioanalysis, leveraging portable analytical tools and techniques, holds transformative potential for remote health monitoring by delivering rapid, accurate diagnostics outside traditional healthcare settings. This article explores how innovations like microfluidics, biosensors, and smartphone-integrated devices enable real-time tracking of biomarkers in underserved and remote regions. These advancements address challenges such as limited access to labs, delayed results, and chronic disease management. Results from recent implementations demonstrate improved patient outcomes, reduced costs, and enhanced data connectivity. While barriers like device standardization and user training persist, POC bioanalysis promises to democratize healthcare, shifting paradigms toward proactive, personalized medicine in remote contexts.
