Pneumatically Driven Microfluidic Platform and Fully Automated Particle Concentration System for the Capture and Enrichment of Pathogens.

In this study, we developed a pneumatically driven microfluidic platform (PDMFP) operated by a fully automated particle concentration system (FAPCS) for the pretreatment of micro- and nano-sized materials. The proposed PDMFP comprises a 3D network with a curved fluidic chamber and channel, five on/off pneumatic valves for blocking fluid flow, and a sieve valve for sequential trapping of microbeads and target particles. Using this setup, concentrated targets are automatically released into an outlet port.
