Abstract: A handheld device for analysis of electrophysiological properties of a cellular membrane ion channel in an ion channel containing lipid cellular membrane includes a handheld body with a pump, an electronic controller, and a disposable pipette tip including a pathway for fluid. The pathway connects an open end of the pipette tip to an analysis substrate in the pipette tip. The substrate is adapted to transmit an electrical current through the ion channel. The handheld body and the disposable pipette tip are configured to releasably attach the pipette tip to the body, to provide a hydraulic connection between the pump and the pathway, and to provide an electric connection between the electronic controller and at least one of the electrodes of the substrate. The electronic controller of the handheld body is configured to operate the assembled device for microfluidic analysis of aspirated fluid.

Abstract: A handheld device for analysis of electro-physiological properties of a cellular membrane ion channel in an ion channel containing lipid cellular membrane comprises a handheld body with a pump and an electronic controller, and a disposable pipette tip comprising a pathway for fluid, said pathway connecting an open end of the pipette tip to an analysis substrate comprised in the pipette tip. The substrate is adapted to transmit an electrical current through the ion channel in said ion channel-containing lipid cellular membrane, when said lipid cellular membrane is held at a predetermined site of the substrate, e.g. for patch clamp analysis. The handheld body and the disposable pipette tip are configured to releasably attach the pipette tip to the body, to provide a hydraulic connection between the pump of the handheld body and said pathway, and to provide an electric connection between the electronic controller and at least one of said electrodes of the substrate.

Abstract: The present invention relates to a structure comprising a biological membrane and a porous or perforated substrate, a biological membrane, a substrate, a high throughput screen, methods for production of the structure membrane and substrate, and a method for screening a large number of test compounds in a short period. More particularly it relates to a structure comprising a biological membrane adhered to a porous or perforated substrate, a biological membrane capable of adhering with high resistance seals to a substrate such as perforated glass and the ability to form sheets having predominantly an ion channel or transporter of interest, a high throughput screen for determining the effect of test compounds on ion channel or transporter activity, methods for manufacture of the structure, membrane and substrate, and a method for monitoring ion channel or transporter activity in a membrane.
