Tests that otherwise require expensive instrumentation and consume valuable reagents can be implemented on microfluidic chips for a fraction of the cost with dramatic improvement in speed. Minaturization offers multiple benefits, enabling multiple tests on one chip, requiring tiny tissue samples and fast reaction times for picoliter volumes. More complex microfluidics chips will be able to carry out sample processing followed by cell or molecule fractionation, molecular analysis and readout of the test result. Integrated platforms incorporating microfluidics offer portable testing devices for \"point of concern\" testing in health care facilities, in remote areas or in the home.

In order to circumvent this limitation, novel drug delivery systems, such as polymeric micelles and lipid-based nanocapsules, are being developed. In general, these nano-sized carriers contain a hydrophobic core which provides the necessary environment to solubilize poorly water-soluble drugs. In addition, when administered intravenously, they can passively target inflamed or cancerous tissues due to the enhanced permeation and retention (EPR) effect, potentially improving the therapeutic efficacy of the drug while reducing its toxicity. Alternatively, the limited oral bioavailability of hydrophobic agents can be improved by selectively releasing the drug in its molecular form close to the absorption site. Polymeric micelles containing pH-sensitive moieties and loaded with a poorly water-soluble drug can dissociate and release their payload in the intestine. This presentation will focus on injectable polymeric and lipidic vectors for hydrophobic anti-cancer agents and on pH-sensitive polymeric micelles as promoters of the oral bioavailability of poorly water-soluble drugs [1].","PeriodicalId":344661,"journal":{"name":"2004 International Conference on MEMS, NANO and Smart Systems (ICMENS'04)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122651848","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 lattice matching of the silicon and iron crystal lattices led to the formation of self aligned silicides at a high temperature which helped orient the nanotubes. SEM, TEM and AFM characterization revealed single wall carbon nanotubes, about 10 nm in diameter and up to 10 μm in length, growing along the <111> direction of the silicon substrate.

An initial perturbation velocity field consisting of a pair of counter-rotating vortices is introduced in Poiseuille and EDL flows and the time-space evolution of the perturbed field is analysed for short times at half the critical Reynolds numbers (3000 for Poiseuille and 300 for EDL). The wall normal and spanwise perturbation velocities development are both quantitatively and qualitatively similar in macro and micro flows. The streamwise velocity, which is initially zero and set up by the generation of the wall normal vorticity is twice larger under the EDL effect. Both flows develop inclined strong streamwise shear layers. Overall is the close similarity of the disturbance evolution showing that the three dimensional linear mechanism in EDL flow lead to the structures that are at least as strong as in Poiseuille flow.","PeriodicalId":344661,"journal":{"name":"2004 International Conference on MEMS, NANO and Smart Systems (ICMENS'04)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134416089","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}

It was found that they have super-elastic properties, and could be extended to 3-15 times of the original spring axis length and contracted to original state after the load was released. The resistivity increased with increasing extension length, and then got recovery after the load was released. This property enables the microsprings to be used as an advanced bulk sensor material in MEMS. Furthermore, the micro-springs exhibited outstanding electromagnetic wave absorption properties in GHz regions.

Simultaneous application of ACdielectrophoresis and membrane filtration can be used for separation of trace amounts of a target species from an emulsion. This can be achieved by embedding inter-digitated microelectrode arrays on a membrane surface used in a cross flow filtration system. The electrode array, when actuated by an AC signal, will create a dielectrophoretic force field to capture the target species onto the membrane surface from the flowing emulsion during cross flow filtration. This paper explains the theoretical principles underlying such a process, and describes a simple mathematical framework based on trajectory analysis for assessing the separation efficiency of the technique. Simulation results indicate that preferential transport of the emulsified water through themembrane in a cross flow filtration device can be significantly enhanced by incorporating an AC dielectrophoretic field in the process. The novel technique proposed here can lead to a highly efficient continuous separation process for dilute emulsions.","PeriodicalId":344661,"journal":{"name":"2004 International Conference on MEMS, NANO and Smart Systems (ICMENS'04)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115937974","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}
