Electrochemical analysis of nitric oxide with the emulsion in imitational of living body

去年获得了单油滴在水中的电化学数据，作为乳状液体系电极反应的模型。本研究将其应用于乳状液油水界面离子的运动。这些结果被9篇论文报道。当油滴分散在水中的乳状液通电时，油滴中存在的氧化还原物质发生电极反应。伴随着离子对转移的反应同时诱导了液滴的聚并（论文4）。利用视频显微镜观察了电势作用下油滴与电极接触角的变化，并讨论了油滴间界面力的变化与电极接触角的相互作用。为了得到一个稳定的界面模型，我们将聚苯乙烯乳胶表面看作一个稳定的油滴表面。合成了含氧化还原物质二茂铁的乳液（论文3）。这些反应显示了部分电荷转移。因此，将胶乳的氧化还原种改为聚苯胺。这与电影中的反应不同。聚苯胺涂层乳胶的反应变得不可逆（论文2）。油-水界面发展为金属-溶液界面。讨论了纳米银颗粒悬浮的分布条件及其电极反应（论文5）。为了得到一氧化氮在生物膜尺度上反应现象的基本数据，用纳米尺度详细描述了相间界面（论文6）。解决了由N0_2电化学生成NO的过程。首先，当施加负电位-0.25 V vs.Ag|AgCl时，N0_2与铁卟啉[Fe^<ll>(TMPyP)]^<4+>配位生成不稳定中间体[Fe^<ll>(NO_2)(TMPyP)]^<3+>。然后在磷酸盐缓冲溶液（pH7.4）中转变为稳定的配位Fe^<ll>(NO)(TMPyP)]^<4+>。最后，通过施加0.8 V vs.Ag|AgCl的正电位，可以从[Fe^<ll>(NO)(TMPyP)]^<4+>溶液中释放NO。目前，油水界面一氧化氮的电化学分析和活体模拟的乳化液基础正在进行中。少

The electrochemical data of single oil droplet in water were got as a model of the electrode reaction of emulsion system in the last year.It was applied to the movement of the ions which are brought on the oil water interface of emulsion in this year. Those results were reported by 9 papers.The electrode reaction of redox species which exists in oil droplet occur when emulsion which oil droplets dispersed in water was applied potential.The reaction accompanied with transferal of the pair ion induces a coalescence of droplets at same time (paper 4).We observed the variance of contact angles between oil droplet and electrode when potential was applied by a video microscope, then discussed the interaction that from the alteration of interface force between oil droplets.In order to get a model of stable interface, we think about the polystyrene latex surface as a stable oil droplet surface. The latexes contained redox species, ferrocene, were synthesized (paper 3).Those reactions of latexe … More s show the partial charge transfer.So the redox species of latex was changed to polyaniline.It was different from the response in a film. The reaction of polyaniline coated latex became irreversible (paper 2).An oil I water interface was developed into the metal I solution interface.The distributed condition of suspension of silver nanoparticle and an electrode reaction of them were discussed (paper 5).In order to get the fundamental data of the phenomenon of nitric oxide which reacting in a film scale of the living body, the interface between phases was minutely described by nanometer scale (paper 6).The process of electrochemical generation of NO from N0_2 has been solved. First, N0_2 coordinated with iron porphyrin [Fe^<ll>(TMPyP)]^<4+> to yield a unstable intermediate, [Fe^<ll>(NO_2)(TMPyP)]^<3+> when applied negative potential -0.25 V vs.Ag|AgCl.Then it was changes to a stable coordinated Fe^<ll>(NO)(TMPyP)]^<4+> in a phosphate buffer solution (pH7.4). Finaly, NO can be' released from [Fe^<ll>(NO)(TMPyP)]^<4+> solution by applied a positive potential 0.8 V vs.Ag|AgCl.At present, electrochemical analysis of nitric oxide in oil | water interface and the emulsion basis of imitational of living body are operating.
