Among them, the integration of natural nanopores such as ion channels with electronics is a promising approach to develop rapid, sensitive and reliable biosensors able to detect low concentration of target molecules or DNA sequencing. This paper presents a compact and low-cost system able to readout, process and record current in the pA range, provided by biological or synthetic nanopores. The approach is based on the idea that by processing the outputs of a large amount of single-molecule nanosensors would result in a significant increase of resolution and signal-to-noise ratio. The approach consists of an electronic interface able to detect current-based array of nanosensors, where the management of very large amount of data is critical for the readout process. As working example, we acquired the single molecule signals derived from non-covalent bindings between single a-hemolysin pores, embedded into an artificial lipid bilayer, and β-cyclodextrin molecules. The system embeds the electronic readout with the microfluidic where is placed the nanosensor array. The electronic interface is a 0.5mm2 current amplifier based on an array of ΣΔ converters. Then the high rate data streams are processed and downsampled by a DSP that communicates with a PC via a USB interface for data processing and storage.","PeriodicalId":246540,"journal":{"name":"2009 3rd International Workshop on Advances in sensors and Interfaces","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116005321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first experimental portal, and a second operative one, have been installed by SIRTI S.p.A., respectively in Rastignano and Formia. Our company, in collaboration with the Laboratory of Optoelectronics of the University of Brescia, have been requested to develop all the multisensor architecture for the dimensional and thermal monitoring of the trains to be installed on the portals. One of the key elements of the portal is the shape acquisition sensor, based on scanning telemetry. In the second portal, based on the experience gathered from the first one, a novel shape acquisition system based on time-of-flight telemeters has been developed. This telemeter has been specifically designed for the high-speed, high-resolution monitoring of trains in railway portals, but can be adapted to a number of industrial and environmental applications.","PeriodicalId":246540,"journal":{"name":"2009 3rd International Workshop on Advances in sensors and Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129452662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CMOS-based, fully integrated microelectrode arrays for bidirectional communication (stimulation and recording) with electrogenic cells are presented. These complex microsystems with integrated filter and amplification stages feature a high electrode density (3'150 electrodes per mm2) as well as low noise levels (3–7 µVrms) in the recorded signals and are capable of monitoring relevant electrophysiological responses of cells to electrical stimuli or to pharmacological agents with prospective applications in the fields of neuroscience or pharmascreening. Results from two exemplary applications are shown. In the first one, the system was used to record the electrical activity of cardiomyocytes. To modulate their electrogenic properties lentivirus-derived particles were selected to regulate the bone morphogenetic protein-2 gene expression. This provides a tool for gene-function studies and for the discovery and preclinical evaluation of novel genes with potential therapeutic effects. In the second application acute sagittal cerebellar slices have been used to assess the performance of the device and to demonstrate its potential for application in the field of neuroscience. Subcellular resolution could be demonstrated and spike sorting allowed for analysing the measured action potentials from single neurons.","PeriodicalId":246540,"journal":{"name":"2009 3rd International Workshop on Advances in sensors and Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130546173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is based on the use of a suitably configured current conveyor architecture providing advantageous noise performance characteristics in comparison to the traditionally used CSA structures. In the proposed architecture the noise at the output of the CSA is independent of the detector capacitance value, allowing the use of large area detectors without affecting the system noise performance. Theoretical analysis and simulation based results are performed concerning the operation - performance of the proposed topology. Measurement results on a current mode CSA prototype fabricated with a 0.35 µm CMOS process by Austriamicrosystems are provided supporting the theoretical and simulation results and confirming the advantageous performance in relation to the traditional voltage mode structures mainly in terms of the noise performance dependency on the detector capacitance value.","PeriodicalId":246540,"journal":{"name":"2009 3rd International Workshop on Advances in sensors and Interfaces","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133872601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
