The microfluidic device consists of two sections - focusing and separation section. The focusing section has two a set of interdigitated transducer electrodes located next to each of the sidewalls. The focusing section subjects all microparticles to negative-dielectrophoresis and focuses the micro-scale entities at the middle of the microchannel. The separation section is downstream of the focusing section and has just one set of interdigitated transducer electrodes. This section subjects one type of microparticle to positive-dielectrophoresis and the other type of microparticle to negative-dielectrophoresis leading to different lateral displacements leading to achieve separation. For purposes of demonstration, a heterogeneous mixture of polystyrene microparticles (5 μm and 10 μm), suspended in water, is separated into two homogeneous samples.","PeriodicalId":118389,"journal":{"name":"2018 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126408260","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 particular, at the nanoscale, the wavelength of operation in the microwave regime appears disproportionate compared to the size of the nano-object under investigation. Incidentally, the microwave characterization results in poor electrical sensitivity as the volume of the wave/material interaction is limited to a fraction of the wavelength. In addition, the definition of nanoscale microwave impedance standards requires accurate knowledge of the material and dimensional properties at such scale. In this effort, a quantitative error analysis performed on micrometric metal oxide semiconductor (MOS) structures is proposed. In particular, atomic force microscopy (AFM) image together with the magnitude and phase-shift images of the complex microwave reflection coefficient using a Keysight™'s LS5600 AFM interfaced directly with a vector network analyzer, without electrical matching strategy, are performed around 9.5GHz. From a detailed analysis of the raw data, completed with a FEM-based electromagnetic modeling, quantitative capacitances extraction and system limitations are exemplary shown.","PeriodicalId":118389,"journal":{"name":"2018 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133921227","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 the last decade, a number of centralized control strategies dependent on native biological mechanisms have been demonstrated; however, decentralized cooperative control of a swarm of bio-hybrid microrobots has not been shown before. In this work, we impart bacteria with engineered biological circuits to facilitate agent-agent communication and enable predictable and robust cooperative control of a network of bacteria-based Biohybrid microrobots. We show a hybrid control strategy wherein a centralized control scheme is used to direct migration and a decentralized control scheme enables the agents to independently coordinate a desired behavior (fluorescent protein expression). We use an experimentally-validated agent-based computational model of the system to demonstrate the utility of the approach. We show that spatial organization plays a significant role in the response dynamics and explore how the system could be tuned for particular applications. The model will serve as an essential tool for predictive design of bio-hybrid microrobotic swarms with a tunable and robust response.","PeriodicalId":118389,"journal":{"name":"2018 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123045540","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}

However, creating tissue-engineered constructs in vitro with both organ-like geometry and biological functions presents unique challenge attribute to complex structure and function of human liver. Here, we have developed photopattern and microrobotic manipulation for fabrication of cellular microtissue in vitro as a substitution of liver lobule as well as liver functions. Poly (ethylene) glycol diacrylate (PEGDA) hydrogel containing hepatocytes are introduced into microfluidic channel to produce cell encapsulated 2D microstructures with lobule-like pattern by photocrosslinking. Microrobotic manipulation is developed for 3D assembly of 2D microstructures into 3D microtissues based on liquid force. To form an integration with lobule-like structure, randomly oriented 2D microstructures are aligned into regular shape by self-alignment process based on hydrophilic-hydrophobic interactions. After the 2D fabrication and 3D assembly process, cells can proliferate and spread in PEGDA hydrogel. During long-term culture, cells perform high viability in both 2D microstructures and 3D microtissues. Albumin secretion of hepatocytes encapsulating in microtissues maintain during the culture period. It indicates that hepatocytes can keep high viability and some liver functions in these microtissues which providing a potential demonstration for biomedical research in the future.","PeriodicalId":118389,"journal":{"name":"2018 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114531166","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}

Microrobots have many uses in cellular environments since they can be remotely actuated and precisely manipulated in biochemical fluids. Most cellular phenomena depend on biochemical signals. Therefore, various techniques have been developed for encapsulation and release of drugs, nutrients or other cargo using microrobots. However, localized targeting without payload leakage during transport is challenging. In this work, we present a light-controlled delivery system integrated with magnetic microrobots which overcomes this challenge. We synthesize a photolabile linker which releases a cell-to-cell signaling molecule when exposed to light. This system is integrated with magnetic micro-robots, which can be steered to target locations in the cell culture. We demonstrate that gene expression in engineered bacterial cells is successfully activated when the signaling molecule is cleaved. This proposed method can be used for wide-ranging applications in the fields of engineering, biology, and medicine, in which the ability to target and release molecules on-demand to a particular location is important.","PeriodicalId":118389,"journal":{"name":"2018 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133428270","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 fundamental of Lissajous trajectory and the MRC technique are presented initially. As the plug-in feature of MRC scheme, a proportional-integral (PI) controller is also designed in feedback loop for realizing the high-precision motion control. The tracking performance of the scanner with PI+MRC is compared with the conventional PI controller to show the effectiveness of the developed method for Lissajous trajectory tracking. The desired Lissajous trajectory and the actual scan trajectory are additionally demonstrated for the scanner with different control strategies. According to the experiment results, the MRC-based technique improves the tracking performance significantly, in which the root mean square tracking error is reduced from 4328nm to 63.3nm for the scanning frequency of 25-Hz.","PeriodicalId":118389,"journal":{"name":"2018 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132156239","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}
