The microscopy image is often the only available sensor to detect information about the positions and orientations of objects. Recently, Field Programmable Gate Arrays (FPGAs) have been used for scanning electron microscope (SEM) image acquisition. Such an FPGA image acquisition system is extended to perform basic image processing and on-line object detection. The connected component labeling algorithm for binary large object detection is presented and analyzed for its feasibility in terms of on-line object detection and classification. The features of binary large objects are discussed and analyzed for their feasibility with a single-pass connected component labeling approach, with focus on principal component analysis based features. It is shown that an FPGA implementation of the algorithm can be used to detect and classify carbon-nanotubes (CNTs) during image acquisition, allowing for fast object detection before the whole image is captured.","PeriodicalId":134364,"journal":{"name":"2012 International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121849168","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}

Two methods have been developed to achieve a large suspended area of graphenes. In the first approach, SF6 plasma was used to make holes or channels with specific dimensions. Then micromechanical exfoliation was applied to deposit the graphene sheet suspended over these channels or holes. In the second method, we used SF6 plasma to make suspended graphenes by undercutting planar graphenes. To tune the number of graphene layers, thick graphene samples was etched layer by layer until the desired thickness was obtained. Additionally, the effect of using various plasmas etching (SF6 or O2) on the layer-by-layer graphene removal has been studied. Raman spectra of plasma-treated graphenes have shown higher amount of defects in case of SF6, specially for thin graphene sheet. However, these surface defects could be recovered by annealing the samples in an argon environment at about 1000 °C.","PeriodicalId":134364,"journal":{"name":"2012 International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128612679","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}

With the increase of normal load from one to twelve microNewtown, the friction force on silicon substrate showed a sharp increase at eight microNewtown, while the friction force on the hillocks kept a stably linear increase. Since no scratch damage was detected on the hillock below a contact pressure of ten point three gigaPascal, the friction induced hillocks on silicon can withstand the typical contact and sliding in dynamic devices. It was also noted that the friction induced hillock presented anisotropic friction and wear behaviors during scratching. The sliding parallel to the scanning direction for producing the hillock can reduce the friction in dynamic devices. This study can shed new light on potential application of the friction induced nanostructures.","PeriodicalId":134364,"journal":{"name":"2012 International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121443841","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}

Lymphoma Raji cells were adsorbed onto the glass slides by coating the glass slides with poly-L-lysine. Rituximabs (anti-CD20 antibody) were linked onto the AFM tip by PEG linker and the CD20-Rituximab binding forces were measured on three lymphoma Raji cells. Then the mechanical properties of the Raji cells were dynamically measured after the Rituximab activation by obtaining force curves on the cell surface. The mechanical properties of lymphoma cells kept stable at the first 20-30 min, and then decreased markedly. Besides, as the CD20-Rituximab binding force increased, the mechanical properties decrease rate increased. The experimental results indicated that the Rituximab's effect is related to CD20-Rituximab binding force and can improve our understanding of Rituximab's variable efficacies in different patients.","PeriodicalId":134364,"journal":{"name":"2012 International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131514947","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 size of powders is distributed from 20nm to 70nm in a typical process according to observation from SEM and TEM images. Based on HRTEM observation, PbTe nanopowders with an amorphous layer show polyhedron feature.

Going from the current proofs of concept on this scale to reliable industrial systems requires the emergence of a new generation of manufacturing methods able to move, position and sort micro-nano-components. We propose to develop `No Weight Robots-NWR' that use noncontact transmission of movement (e.g. dielectrophoresis, magnetophoresis) to manipulate micro-nano-objects which could enable simultaneous high throughput and high precision. This paper focuses on developing a 2D robotic control of the trajectory of a micro-object manipulated by a dielectrophoresis system. A 2D dynamic model is used to establish an open loop control law by a numerical inversion. Exploiting this control law, a high speed trajectory tracking (10 Hz) and high precision positioning can be achieved. Several simulated and experimental results are shown to evaluate this control strategy and discuss its performance.","PeriodicalId":134364,"journal":{"name":"2012 International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116876492","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}

Silicon nanowire-based field-effect transistors (SiNW FETs) have been experimentally demonstrated for direct, label free, highly selective, and real-time detection of biological and chemical targets at very low concentrations. The detection of a target is based on the variation of conductance of the nanowire channel which is seen in the voltage-current behavior between the drain and source. Some current, known as leakage current, flows between the gate and drain, and affects the current between the drain and source in noise-like manner. The current is extremely low at DC, and can be ignored in most cases. Recent studies suggest, however, that the leakage current is likely to exhibit frequency-dependent characteristics. Recognizing such properties can possibly take great advantage in developing new detection technologies utilizing SiNW FETs. This paper applies the maximum-length binary sequence (MLBS) and spectrum method, and presents fast frequency-domain methods which can be used to measure and characterize the leakage current. Experimental measurements are shown from an n-type SiNW FET. The results clearly indicate the existence of the mentioned frequency-dependent characteristics.","PeriodicalId":134364,"journal":{"name":"2012 International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122230484","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}
