Monitoring proliferative activities of hormone-like odorants in human breast cancer cells by gene transcription profiling and electrical impedance spectroscopy

Horst Vogel, Horst Pick, Cathrin Brisken, Samuel Terrettaz, Olivia Baud

The human estrogen receptor alpha (ER!) mediates the proliferative action of hormones in breast cancer cells by regulating the expression of target genes to control cellular functions. Current methodologies do not permit a real-time assessment of these pro ...

A synthetic membrane protein in tethered lipid bilayers for immunosensing in whole blood

Horst Vogel, Samuel Terrettaz, Solomzi Makohliso, Stéphanie Follonier

Tethered lipid bilayers, containing a transmembrane synthetic ligand-gated ion channel (SLIC), have been formed on gold surfaces. The SLIC was designed as a highly selective receptor and reporter protein to detect antibodies in whole blood, which are of im ...

Real-time high-sensitivity impedance measurement interface for tethered BLM biosensor arrays

Giovanni De Micheli, Horst Vogel, Carlotta Guiducci, Samuel Terrettaz, Yusuf Leblebici, Luca Benini, Yüksel Temiz

This paper presents a switched-capacitor (SC) current integrator circuit for impedance measurement of tethered bilayer lipid membrane (tBLM) biosensors. The circuit comprises a small number of high performance components enabling enhanced experimental flex ...

Impedance spectroscopy of ion channels in tethered lipid bilayers

Horst Vogel, Samuel Terrettaz

A review. The efficient anal. of the function of ion channels is an important task in many different fields ranging from (bio)analytics and drug-screening to nanoelectronics. Here, the modulation of the channel activity of a synthetic ligand gated ion chan ...

Investigating the function of ion channels in tethered lipid membranes by impedance spectroscopy

Horst Vogel, Samuel Terrettaz

A review. The function of biol. important ion channels can be measured in supported lipid membranes by impedance spectroscopy. This approach offers substantial advantages over traditional electrophysiol. measurements. In this article, we present an overvie ...
