Traveling wave bio-agent concentrator

 

This paper describes a hybrid bio-agent concentrator device based on the combined performance of a modified field flow fractionation device for particulate deposition and a traveling wave transport mechanism to deliver and concentrate particulates into a sample well. The operating principles are based on MEMS technology for precise particulate control and manipulation. This device may increase the concentration of post-ultrafiltration retentates or post-aerosol collected hydrosols by another 100X. As a front-end to detection, it will enhance the effective sensitivity of the detector. The device may also have bio medical implications in cell enrichment.
