Strong reflection induced by larger index mismatch and longer optical path from GNPs-protein conjugation are suggested to attribute most to the signal enhancement in F-P interference shift. The experiments carry out the monitoring of immuno-sensing in real-time by the employment of rabbit IgG conjugate to GNPs-anti-rabbit IgG And the detection limit was demonstrated to approach 0.17 nM (-25.5 ng/ml), which was three orders of magnitude better than those of the traditional fiber-based F-P biosensors. Besides, the reproducibility of the sensor has been tested through at least three cycles of detection/surface-regeneration process and demonstrated a reasonable consistency. The relationship between the concentrations of GNPs-antibody and F-P spectrum shift has also been characterized. The time-constant of this sensor to complete one cycle of biomolecule-detection and surface-regeneration can be as low as 4 minutes.","PeriodicalId":6388,"journal":{"name":"2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75319428","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 design A, rows of fins composed of high conductivity silicon are bonded onto a 100 mum thick base plate composed of low conductivity Pyrex glass. This planar device has a footprint of 6times1.5 cm2 and 2.5 mm thickness, and is fabricated using a 5-mask process. In design B, numerous high-conductivity silicon plates alternating with low-conductivity Pyrex spacers are stacked together. This has a footprint of 1times1cm2, a length of 1.4 cm, and is fabricated using a 3-mask process. Preliminary experiments show that the primary performance constraint for design A is imposed by the compromise between mechanical robustness and transverse conductance of the thin glass base plate that separates the high pressure and low pressure streams. Design B enhances the robustness of the device and can sustain higher pressure.","PeriodicalId":6388,"journal":{"name":"2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84461458","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}

MRI holds promise for in vivo characterization due to its potential for obtaining high-resolution images and its sensitivity to the compositional characteristics of lesion. By placing a receive coil in the human body, NMR signals from the tissue surrounding the coil can be detected sensitively and the method enables in vivo high-resolution imaging (high spatial resolution and high spectroscopic resolution). The preferable receive coil has homogeneous RF receptivity around the probe and high-SNR. Novel coil designs and/or multi-coil have capabilities to meet these demands. To connect the tuning/matching circuit and amplifier circuit near the coil is needed to improve SNR of the system. Microfabrication on cylindrical substrate is one of methods for fabricating arbitrary coil pattern and the tuning/matching circuit on the tube with small diameters. Using a maskless lithography technique, solenoid coil, tilted coil and saddle shaped coil have been fabricated on glass tube with 2 mm O.D.. Imaging test of the coils were performed on 3 T MRI in a 2% agar phantom.","PeriodicalId":6388,"journal":{"name":"2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77272337","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 their tiniest, ultimate realization, NEMS will be formed with sub-nanometer scale precision from atomic- and molecular-scale mechanical elements as first envisaged by Feynman (1). Although nanowire and nanotube based NEMS today verge on this domain, their assembly into functional devices remains more of an art than a science, as they are typically fabricated one-by-one by complicated means with low yield. By contrast, the most robust forms of NEMS are currently patterned by top-down methods; in fact their production is now being scaled to enable large-scale integration over 200 mm wafers with minimum feature sizes that are below 50 nm. In this paper I will describe how nanoscale mechanical elements provide benefits beyond the obvious, that is, benefits in addition to the possibility of increased device density. The reduced size of NEMS enables mechanical functionality that completely transcends what is possible at the microscale with MEMS (2). However, size reduction to the nanoscale may not be a panacea for all applications - for some applications larger may still be better!","PeriodicalId":6388,"journal":{"name":"2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85782097","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 platform is roughly 8times7times1.5 mm3 in size with probe thickness of 200 mum and weighs 500 mg, which the moth is able to successfully carry in the adult stage. In addition to the microsystem, an anchor to easily manipulate the adults was successfully formed in the insect by placing a glass-capillary through the pupae. The pupae emerged successfully, and the microsystem was used to characterize the potential for flight control. As part of the work to determine the microplatform design, we determined the strength-interval profiles of the pulses needed for direct muscle actuation. Two sets of flight muscles, which are symmetrically present on either side of the thorax, were differentially electrically actuated, which potentially influences the individual wing beat frequency and amplitude resulting in controlled turning behavior during flight.","PeriodicalId":6388,"journal":{"name":"2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88452805","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}
