The very porous and fine precipitated matrix facilitated the permeation of a sample solution into the flow channel and the dissolution of the components. The amount of products produced as a result of the enzymatic reactions was sufficient and a significant increase in the resulting sensor output was observed. The applicability of the device was demonstrated in the determination of the activities of enzymes, the analysis of enzyme kinetics, and the monitoring of a multi-step reaction. This can be a basic technology in conducting microfluidic diagnostic systems with higher functions including the analysis of enzymatic reactions.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134035294","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 porous silicon substrates were prepared by the electrochemical etching process first. Then, by sol-gel technique, it is possible to obtain a uniform Zinc Oxide films on the porous silicon substrates. The electrical conductivities of the porous silicon and Zinc Oxide modified porous silicon structures under different humidity levels were measured. Our study indicate that the modification of porous silicon by sol-gel Zinc Oxide increase the sensitivity and shorten the response time to the relative humidity, probably due to the increment of the specific surface area of the porous silicon. The other parameters, such as the concentration of zinc oxide precursors, which can affect the sensing performance, were also discussed. Therefore, the Zinc Oxide modified porous silicon composite structure studied is potential to develop the humidity sensor with high performance.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131510900","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}

Special attention has been paid in this work to explore the Q limitations of single-crystal silicon bending beam resonators and their dependences on geometry, temperatures and pressure for a large range of resonators. In order to preserve the resonating element from support damping, a system with high decoupling efficiency has been optimized using FEM analyses and implemented. Quality factor as a function of frequency shows the transition between thermoelastic damping (TED) and surface damping as limiting mechanism with the miniaturization of the resonators: At high vacuum, the thermoelastic theory is experimentally validated to be the main damping source for Q up to 4.0x104. Beyond these values (Q > 1.4x105) the surface effects are evidenced and characterized with thickness and frequency variations.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130955502","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 application a reliable and rapid gas sensor is required for process control to assure a continuous CO2 concentration below 2%. The obtained results compared favorably with a state of the art NDIR analyzer used as a reference with the distinct advantage of faster response times.

Each sensor uses a stainless steel substrate, a laminated stainless steel film as a suspended movable plate and a fixed, surface micromachined back electrode of electroplated nickel.

For this reason, we developed a new Localized Surface Plasmon Resonance (LSPR) based label-free optical biosensor in connection with a Porous Anodic Alumina (PAA) layer chip. For the fabrication of PAA layer chip, a double oxidation step method was developed, which used oxalic acid as oxidizing agent at an oxidation voltage of 40 V. In our sensor, the absorbance at surface of PAA layer chip resulted in an interferometric pattern that was related to the LSPR optical properties of bio-molecules. All absorbance spectra were taken from 400 to 850 nm on the UV-visible spectrophotometer at room temperature. The absorbance strength increased with the formation of double-helix with the probe target DNA hybridization. The reaction of mismatch DNA did not cause a significant increase in the absorbance, but only a slight bathochromic shift was observed. However, the binding of match DNA caused a significant bathochromic shift and increase in the absorbance indicating the complete hybridization. We expect that this detection method using LSPR based label-free optical biosensor can be used for analysis conveniently with high sensitivity, because there is no necessity of labeling such as the enzymes and the fluorescent dye.","PeriodicalId":233838,"journal":{"name":"2006 5th IEEE Conference on Sensors","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133674798","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}
