    摘要: A polymeric material such as PDMS is molded into an electrode structure containing a micron-size aperture for receiving and forming a giga-ohm seal with a biological membrane. One end of a tube is filled with uncured polymeric material and pressed against a support surface to prevent drainage. A conventional micropipette having a size suitable for sliding through the tube is introduced, tip first, into the tube and is allowed to fall through the polymeric material and rest against the support surface. The assembly is heated to cure the polymer and the micropipette is removed from the tube, thereby leaving a polymeric plug at the end of the tube with an aperture suitable in shape and size for patch-clamp giga-ohm seal electrode applications. A multi-well tray with a polymeric electrode plug in each well is constructed using the same approach.
