Abstract

An antenna is used for radio frequency measurements of cell wall impedance changes due to ion channels. The antenna provides enhanced direct readout of lipid bilayers and cells containing pores and ion channels. The antenna is placed around a nanopore, which may be fabricated from glass, quartz or other material, and is shaped to provide an enhanced sensitivity to electrical activity in the vicinity of the nanopore. As such, the antenna may be of a class of bi-cone- or other stub-antennas providing high gain and broad bandwidth, for example a planar variant of a “bow-tie” antenna. Accordingly, improved sensitivity of at least an order of magnitude may be achieved over past systems.
