| Research Abstract |
Sensing bacteria is attracting a great deal of interest to avoid an outbreak of bacterial infection. The sensors used for this purpose should integrate at least two functions in a small volume: trapping bacteria and detecting them. We developed a PDMS-based microfluidic chip for trapping and detecting L. pneumophila cells. By using our finding that L. pneumophila might emit fluorescence when they are forced to limit their motion in a narrow space, we can observe fluorescence from L. pneumophila cells introduced into the chip together with microbeads: We previously make a mixed suspension of L. pneumophila cells and the beads and then introduce them into the microfluidic chip with funnel-shaped protrusions which work as stoppers both for the cells and the beads. The cells are densely packed at the inlet side of the stoppers and restricted their motion confined by microbeads. This method enables us to expect the observation of fluorescence from the L. pneumophila cells introduced.
