Therefore the test methodology should be applicable to the study of a wide range of materials.

In the experimental study, we measure the cytosolic component (Ca++ ion) from each single RBC and verify population analysis of single cells in mixed cell populations. Thus, this work shows that the present flow-lysometry is useful to characterize complex cell populations, which is required for various biomedical studies.","PeriodicalId":187850,"journal":{"name":"2009 IEEE 22nd International Conference on Micro Electro Mechanical Systems","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125677630","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 dynamic patterning of nanoparticles was achieved by a standing surface acoustic wave (SSAW), from which the acoustic force generated and force the particles to the pressure nodes. The SSAW were formed through two parallel interdigital transducers (IDTs) on a LiNbO3 substrate, on which the gold nanodisk arrays were fabricated through a nanosphere lithography. A PDMS microchannel was aligned with the IDTs and bonded with the substrate to cover the nanodisk arrays. A solution of fluorescent polystyrene beads (diameter: 320 nm) was injected into the channel through a pressure driven flow.

The so called StarJet dispenser utilizes a star-shaped nozzle geometry that stabilizes plugs of liquid in the centre of the nozzle by capillary force. This minimizes the wall contact of the liquid plug and reduces contact line friction. Individual droplets of liquid metal can be pneumatically generated by interplay of the sheathing gas flow in the outer grooves of the nozzle and the liquid metal. The working principle was first discovered and studied by Computational Fluid Dynamic (CFD) simulations. For experimental validation silicon chips with the star-shaped geometry were fabricated by Deep Reactive Ion Etching (DRIE) and assembled into a printhead. With different nozzle chips volumes between 120 pl and 3.6 nl could be generated at natural frequencies of 90 Hz and 400 Hz. The StarJet can either be operated as drop on demand or as continuous droplet dispenser. We printed columns of metal with 0,5 to 1,0 mm width and 40 mm height (aspect ratio ≫40) to demonstrate the directional stability of the ejection.","PeriodicalId":187850,"journal":{"name":"2009 IEEE 22nd International Conference on Micro Electro Mechanical Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134538744","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}

Currently used Couette rheometer drives the blood flow at a certain shear rate and measures the viscosity from the resistance toque towards the rotational shaft. Although effective, conventional rheometer is limited due to the complex configuration and the relatively large sample volume. More important, the rotating components hinder the miniaturization for point-of-care and unattended diagnosis. To address this, a microchip is reported for measuring the blood viscosity from the electrical impedances of the blood flowing inside a microchannel. This microdevice is advantageous over rotational viscometers in less sample consumption, rapid response and simple configuration. Considering the vital role of blood viscosity in cardiovascular disorders, this microchip provides a promising start point for on-chip hematological diagnosis.","PeriodicalId":187850,"journal":{"name":"2009 IEEE 22nd International Conference on Micro Electro Mechanical Systems","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134576228","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}
