| Outline of Final Research Achievements |
We studied formation of artificial planar lipid bilayers and their application in drug permeability assay by using microfluidic channels fabricated on a planar substrate. Nanoliter-sized aqueous donor and acceptor droplets were continuously formed at T- or cross-shaped channels into a lipid-containing organic stream. At the downstream, selective aspiration of the organic phase brought the aqueous donor and acceptor droplets into contact, thereby creating droplet interface bilayers (DIBs). Furthermore, we could rapidly measure passive membrane permeability of drug molecules across the formed DIBs.
