Microfluidic devices offer significant advantages in the field of epidemiology by providing cost-effective, rapid, and highly sensitive diagnostic methods. These devices can be used for pathogen detection, tracking disease spread, and monitoring public health. The miniaturization of assays reduces the amount of reagents and samples needed, thereby lowering costs and enabling high-throughput screening. Moreover, microfluidic platforms can be integrated with lab-on-a-chip technologies, allowing for portable and on-site testing, which is crucial during outbreaks or in resource-limited settings.
