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

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

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 ...

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

Horst Arthur Vogel, Samuel Terrettaz, Solomzi Makohliso

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 ...

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

Horst Arthur Vogel, Cathrin Brisken, Horst Pick, 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 ...
