In order to realize a portable, rapid and hand held biosensor of cortisol, we proposed an immuno-chromatographic test-strip based biosensor consisting of a disposable test-strip and a monitor. A fabricated disposable type test-strip has a size of 5 × 1.5 × 50 mm3. In order to realize an immuno-chromatographic test-strip, a glucose oxidase (GOD)-cortisol conjugate was newly synthesized, because the speed and selectivity of immunological reactions is particularly attractive as a strategy for molecular recognition of cortisol. The synthesized molecule was identified as the GOD-cortisol conjugate by both its molecular weight and specific detection of cortisol. Three min after addition of GOD enzyme assay solution, a color change reaction at a test line was observed. The R2 value for the calibration curve of the cortisol test strip was 0.95, and the relationship between its reflectance, r, and the cortisol level was r = 0.629 (1−0.232e(−1.78 × cortisol)). The fabricated cortisol biosensor enabled us to analyze cortisol concentrations between 1 – 10 ng/ml within 25 min of dropping a cortisol solution on the test strip. Thus, it is suggested that the cortisol biosensor may possibly be used for point-of-use measurements in hospitals.","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"214 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131494269","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}

Single cell could be firstly trapped in the microcavity by negative DEP force between top and middle electrodes without overlapping problem; then, the trapped cells were sensed its impedance by sweeping AC signal in between middle and bottom electrodes. As the experimental results, the impedance of higher-grade bladder cancer cells was smaller than the value of lower-grade bladder cancer cells, i.e., TCCSUP (grade IV) ≫ TSGH8301 (grade II), and the impedance of normal bladder cell was much higher than the values of both cancer cell lines. Basically, the impedances of all kinds of cell lines were decreased with the delay time measured when cells were taken out of the incubator. The largest difference of impedance between normal cells and cancer cells occurred as the delay time reached 1 hour, furthermore, the ratio of impedance between cancer cells and normal cells measured at 1 KHz and 0.2 V were 54% and 22% for TSGH8301 and TCCSUP, respectively. Consequently, the possibility of impedance measurement for evaluation of cancer cells was first proposed and investigated; moreover, the microchip provides the potential of electrical sensing for in vitro diagnosis under single cell resolution.","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122263171","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 work proposes a novel fabrication process to fabricate Pd-NEE using electroless deposition of Pd in a thin porous polycarbonate (PC) film for high performance electrochemical detection. Scanning electron microscopy (SEM) in conjunction with energy dispersive X-ray spectroscopy (EDS) are used to characterize the morphology and composition of Pd-NEE. It shows the best performance for hydrogen evolution reaction on Pd-NEE than other electrodes including bulk Pd, bulk Au and gold nanoelectrode ensemble. The Pd-NEE has a linear peak current response of the removal of adsorbed hydrogen over the tested sample concentration range. The effect of scan rate for voltammetric analysis is investigated. It is found that peak currents decrease as the scan rate from 0.5–0.05 V/s, but increase as the scan rate is lower than 0.05 V/s. It is demonstrated that hydrogen absorption and desorption on Pd-NEE is faster than that on other materials. A high electrocatalyst system is developed for hydrogen evolution reaction (HER).","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122337895","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}
