Riaud, Jia Zhou","doi":"10.1109/NANO46743.2019.8993913","DOIUrl":"https://doi.org/10.1109/NANO46743.2019.8993913","url":null,"abstract":"Compartmentalization of aqueous samples into micro-droplets enables to study single cells or detect single molecules by performing large number of independent experiments. However, as the droplet size becomes smaller, the surface energy becomes larger so that micro-channels or surface treatments are required to break droplets below the picoliter range, resulting in an increased experimental or chemical complexity. Herein, we study the spontaneous liquid film breakup observed after smearing a mother droplet on the surface of lotus leave reversal. As the film breaks and recedes, it is mechanically trapped in single wells formed by the natural bulges on the leaf and forms picoliter droplets, which we called anti-lotus effect droplet. The bio-inspired effect has the advantage of resisting capillary forces and releasing surface tension in the three-phase interface. Using soft-lithography and spin-coating, we obtain the bio-mimetic wells array with the corrugated surface analogous with the lotus leave, which enables a deeper liquid penetration during the smearing step that results in a more efficient filling of the wells. In the present experiments, we have obtained a regular array of 2 pL droplets with a density of 62,500 droplets/cm2, which equivalents to 5.4 million droplets on the surface a 96 well plate. This bio-inspired method of forming droplet will be a convenient way to operate with no chemical treatment and seal. It undoubtedly decreases the complexity of chip manufacturing and potential interference by chemical treatments. We believe that such a method contributes to the development of the efficient micro-droplet generator with a pure physical interface and thus is applicable to biological and medical analysis.","PeriodicalId":365399,"journal":{"name":"2019 IEEE 19th International Conference on Nanotechnology (IEEE-NANO)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114664769","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}

Since Alginate-poly-L-lysine alginate microcapsules can provide a liquified environment for biomaterials, traditional fabrication methods such as microfluidic gelation can tune the size and biochemical properties of hydrogel microcapsule, but still, undergo tremendous challenges while tuning the morphology of the hydrogel microcapsules. In this work, we proposed a novel approach to fabricate Janus Alginate-Poly-L-lysine Alginate microcapsule with controllable shape and size based on a two-step hydrogel electrodeposition method. The microelectrode device (fluorine-doped tin oxide (FTO) glass) was etched into two insulating parts by laser processing. After the first step, the electrodeposition solution was removed by adding HEPES solution. During secondary electrodeposition, a higher voltage was employed, since the entrapped hydrogel and unremoved HEPES solution remains upon the surface of the fluorine-doped tin oxide (FTO) glass. After the two-step deposition, the 2D hydrogel Janus structures were detached from the FTO glass. Then they were immersed in Poly-L-lysine solution. Then the 3D Alginate-poly-L-lysine alginate (APA) microcapsules were successfully fabricated and incubated for further observation. We have demonstrated a successful encapsulation of HepG-2 cells in the half of the APA hydrogel microcapsule and the cells are cultured for several days and Janus APA microcapsules are embedded with fluorescence-labelled and non-labelled HepG2 cells to monitor the cell morphology, distribution, as well as their proliferation.","PeriodicalId":365399,"journal":{"name":"2019 IEEE 19th International Conference on Nanotechnology (IEEE-NANO)","volume":"20 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113964575","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 ML, the magnetic domains are considered to render logic levels instead of electric charge used in CMOS based digital circuits. The spins in single domain magnetic dots are used to represent logic levels and magnetic coupling between neighboring dots is employed to realize the computational output. The ML design involves arranging dots along ferromagnetic and antiferromagnetic ordering to achieve a desired digital output. The optimum dimensions with shape of the dots, spacing between the dots, and few primitive digital gates were extensively studied in the past. In this paper, magnetic dots were arranged to exhibit carry ripple based full adder circuits. One bit and two bit full adder circuit was designed in an open source micromagnetic simulator and transient energy profile is used to propose footprint, delay and energy models for ML based higher order adder subsystems. The proposed ML based adder circuit was compared with other CMOS technology related adder circuits. The proposed model offers insights to design a large ML based digital system.","PeriodicalId":365399,"journal":{"name":"2019 IEEE 19th International Conference on Nanotechnology (IEEE-NANO)","volume":"76 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128069795","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}
