Among the available detectors, SQUIDs are the most sensitive magnetic field and flux detectors and are rapidly approaching the quantum sensitivity limit. To reach such sensing capability, technological advances in the fabrication of nanoscale SQUIDs with submicrometric loops are needed. In this work we present a novel process for the fabrication of nanoscale SQUIDs, based on superconducting vertical Nb nanoconstrictions. The fabrication process uses laser lithography to define the device geometry, focused ion beam to mill the top surface of the Nb in a nanometer-sized region across the width of the film and anodization to define the final thickness of the nanoconstriction and at the same time to embed the ion-implanted amorphous layer produced by the FIB milling step. A preliminary electrical characterization of nano-sized single Josephson junctions and SQUIDs fabricated with this process is also reported.","PeriodicalId":299019,"journal":{"name":"2016 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124310990","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 this study, the objective is to achieve higher sensing sensitivity by enhancing the stress transfer between thin film/Substrate. To this aim, polyimide substrate was exposed to oxygen plasma treatment in order to activate and enhance the surfaces prior deposition of the MWCNTs/epoxy nanocomposite thin film. In fact, exposure time was varied 2, 4, 5, 10 min in order to investigate the impact on the electro-mechanical response. For deeply investigation, Atomic Force Microscopy (AFM) was used to examine the topography of the modified surfaces of the kapton HN by measuring the root-mean-squared (RMS) roughness. The AFM results show that the root-mean-squared (RMS) roughness of pristine PI film was 2.5 nm, increasing to 15.5 nm after 4 minutes oxygen plasma treatment. Furthermore, Raman spectroscopy was used to follow the changes on the molecular structure of surface following treatment time. A higher sensitivity was achieved after 4 min plasma with a gauge factor around 13.6.","PeriodicalId":299019,"journal":{"name":"2016 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115148130","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}

Such a concentration level has been recently identified in a contrast dose of 1.50 mg/mL., which has been shown to be particularly suitable for automatic HNT detection within echographic images acquired through a clinically-available ultrasound device employing conventional diagnostic settings. The dose- and time-dependent cytotoxicity of uncoated and PEG-coated HNTs was evaluated in vitro by MTT cell viability assay carried out on two different human cell lines: SKOV-3 (human ovarian carcinoma cells) and MG-63 (human osteosarcoma cells). Cells were each time incubated for 6 to 72 h in the presence of HNTs at a concentration ranging from 0.25 to 1.5 mg/mL before the MTT test was performed. Obtained results showed that, for both the considered cell lines., viability was substantially unaffected for any tested combination of incubation time and PEG-coated HNT concentration. On the other hand., when the cells were incubated with uncoated HNTs significant reductions in viability (indicative of cytotoxic effects) were visible after a 48-h incubation for each adopted nanoparticle dose. On these bases., PEG coating can be considered a highly effective method to improve the biocompatibility of HNTs., which in turn has a very strong potential for an effective employment as ultrasound contrast and drug delivery agent.","PeriodicalId":299019,"journal":{"name":"2016 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125191273","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}
