Abstract
The study presents a new microfluidic system integrated with three functional devices of pumping, mixing and separating for virus sample pretreatment, analysis and detection. By using antibody-conjugated magnetic beads, the virus sample can be purified, enriched and detected with a higher sensitivity and selectivity. Moreover, the integrated micro-system can perform automatic incubation, transportation, mixing, and purification, possibly making it a crucial platform for future biological and medical applications. © 2006 Society for Chemistry and Micro-Nano Systems.
