In order to harness the low power characteristics of Ultra Wideband (UWB) systems, issues involving the synchronization of extremely short pulses have to be resolved as they surface as major bottlenecks of the design of such systems. The situation is particularly adverse in short range communication systems operating in dense indoor environments as employed in the biomedical field. In this paper, we present a simple power saving synchronization scheme extended upon a previously implemented spatial rake receiver structure. This scheme, which uses neither high speed ADCs nor conventional analog correlators, allows for significant reduction in receiver power consumption while achieving quick acquisition in the preamble stage under moderate signal to noise ratio (SNR) conditions, by exploiting favorable cross correlation properties of known Barker sequences. This is illustrated by appropriately adjusting the threshold value of the discrete correlation between received data and chosen sequences.","PeriodicalId":415200,"journal":{"name":"2008 IEEE Biomedical Circuits and Systems Conference","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132551499","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}

As a result, hundreds to millions of tests can be performed simultaneously and can facilitate rapid detection of multiple pathogens in a given sample. However, it is an open question as to how to exploit the high-dimensional nature of the multi-pathogen testing for improving the detection reliability of typical biosensor systems. Our research over the past few years has addressed this question and in this paper we briefly summarize our approach. Our underlying principle is based on a forward error correcting (FEC) biosensor where redundant patterns are synthetically encoded on the biosensor. A decoding algorithm then exploits this redundancy to compensate for systematic errors due to experimental variations and for random errors due to stochastic biomolecular interactions. The key milestones in this research are : (a) fabrication and modeling of biomolecular circuit elements used for constructing the FEC biosensor; (b) development of a simulation environment for rapid evaluation of encoding/decoding algorithms and (c) development of a ldquoco-detectionrdquo protocol that exploits non-linear interaction between different biomolecular circuit elements. As a proof-of-concept our study and experimental results have been based on a conductimetric lateral flow immunosensor that uses antigen-antibody interaction in conjunction with a polyaniline transducer to detect the presence or absence of pathogens in a given sample.","PeriodicalId":415200,"journal":{"name":"2008 IEEE Biomedical Circuits and Systems Conference","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123954765","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}

In case of high risk side effects, e.g. therapies with interfering anti-cancer molecule cocktails, direct monitoring of the patientpsilas drugs metabolism is essential as the metabolic pathways efficacy is highly variable on a patient-by-patient basis. Currently, there are no fully mature point-of-care bio-sensing systems for drugs metabolism monitoring directly in blood. The aim of the paper is to investigate solutions to develop point-of-care systems for drugs monitoring in personalized therapy. P450 enzymes are the considered probe molecules as they are key proteins directly involved in drugs metabolism of humans. Sensitivity improvement is ensured by means of enzyme integration onto electrodes structured with carbon nanotubes. Component Off-The-Shelf (COTS) based circuits design is investigated toward bio-chip development. Results show that the proposed circuitry is suitable for the aim and confirm that nanotubes are detection enhancers.","PeriodicalId":415200,"journal":{"name":"2008 IEEE Biomedical Circuits and Systems Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127542682","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}
