Aqueous-phase gold nanoparticles (AuNPs) extracted with 4-(dimethylamino) pyridine (DMAP) from toluene solvent is used as the reaction probes. The conjugated AuNPs of the diameter around 13 nm disperse into the size of 2-5 nm while adding dopamine (DA), resulting in the color change of the AuNPs solution from red to green. Therefore, the extracted AuNP solution can be a good indicator for detecting DA biosample. Transmission electron microscope (TEM) observations and dynamic light scattering (DLS) tests show that the AuNPs turn into smaller size right after adding DA. Results confirm that the DMAP capped AuNPs are etched by the DA molecules due to the stronger affinity between DA and AuNPs and thus cause a blue shift in the absorption spectrum. The concentration of dopamine is quantitatively monitoring using an UV-vis spectrometer with a limit of detection (LOD) of lower than 5 nM. The developed AuNPs etching protocol for dopamine detection provides a novel and versatile approach for rapid biosensing applications.","PeriodicalId":156839,"journal":{"name":"2012 7th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"24 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120918348","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}

Based upon these testing results, a new method for frequency matching is presented. Compared to traditional harmonic vibration, large amplitude and wide shift resonance frequency could be obtained in stable region of nonlinearity by using this approach, especially, in this region gyroscope could spontaneously vibrate at a certain driven frequency without needing sweep-up frequency excitation. In our tunneling gyroscope, the vibration amplitude changes from 1μm to 5μm at jumping-up point J' with the amplitude of the excitation electrostatic force increasing. At the same time, the resonant frequency of driving mode can be shifted from nature frequency 1.81 kHz to 2.2 kHz, which is much closed to the resonant frequency of sensing mode (2.23 kHz). This effect can be used as an alternative approach to trim the frequency and eliminate the frequency mismatching for the post-fabrication tunneling gyroscope, eventually, higher sensitivity could be gotten than using linear driving mode.","PeriodicalId":156839,"journal":{"name":"2012 7th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131168880","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}

Both mechanical strength and piezoelectric characteristics of a single nano-fiber were discussed. NFES technology can be used to fabricate PVDF piezoelectric fibers with an excellent piezoelectric property. By adjusting velocity of a x-y stage, DC voltage, and the distance between the needle and collector, the morphology and polarization intensity of piezoelectric fiber can be controlled. In addition, the optimal parameters of PVDF solution such as weight percentage of PVDF powder and MWCNT were also discussed. From the observation of XRD (X-ray diffraction), it reveals a high diffraction peak at 2θ=20.8° of piezoelectric crystal β-phase structure with PVDF/MWCNT spherical composite structures in fibers. Actuation property of fixed-fixed single PVDF fiber structure was tested using DC voltage supply, and the fiber has significant deflection in the experiment. The vertical deflection can be observed and compared with model solution.","PeriodicalId":156839,"journal":{"name":"2012 7th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114906663","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}
