Single-channel recording using artificial lipid bilayers is along with the patch-clamp technique a very powerful tool to physiologically and pharmacologically study ion channels. It is particularly advantageous in studying channels that are technically difficult to access with a patch pipet. However, the fragility of the bilayers and the difficulty to incorporate ion channels into them significantly compromises measurement efficiency. We have developed a novel method for forming artificial lipid bilayers on a hydrogel surface that significantly improves the measurement efficiency. Bilayers formed almost instantly (<1 s) and were able to incorporate various types of ion channel proteins within a short time (<30 s) enabling multichannel measurements. These results indicate that this method can potentially be applied to developing high-throughput screening devices for drug design.
