Abstract
Detection of target substances at very low concentration by using molecular stochastic sensing might open new directions for diagnostic tools. This paper presents a compact and low-cost electronic system to record events derived from ligand-gated ion channels embedded in an array of artificial lipid bilayer substrates. In our approach, a Surface Mount Technology electronic system has been designed to be interfaced with a 4x3 array of spots. The currents through each spot of one row are concurrently readout and digitized by three current-mode DeltaSigma (Delta Sigma) analog to digital converters. The output data streams are sent to a digital acquisition card for being recorded and post-processed by a PC.
