Abstract

We examined the robustness of suspended bilayer lipid membranes (BLMs), aiming for portable sensor systems. BLMs are highly likely to rapture at their natural frequencies, therefore the natural frequencies of BLMs need to be set above the frequencies of vibration that the sensor experience during operation. We used a micro split-and-contact device to form BLMs with good reproducibility and applied the device to vibration tests to deduce the natural frequency, where we investigated the BLMs area and the incorporation of a nanopore-forming protein into BLMs. We conclude that larger BLMs area and the protein incorporation decreases the natural frequency of BLMs.
