電化學(xué)摘要，求翻譯，拒絕軟件翻譯

銅蛋白(cuprein)廣泛存在于生物體中，銅蛋白有多種生理功能，比如載氧、傳遞電子、作為氧化劑等。血藍(lán)蛋白(Hemocyanin, HC)和二胺氧化酶(Diamine oxidase, DAO)均為含銅的蛋白質(zhì)。血藍(lán)蛋白是動物界三大呼吸蛋白之一，是一種多功能蛋白質(zhì)，不僅具有輸氧功能，還具有調(diào)節(jié)動物體滲透壓，儲存能量等作用，相關(guān)研究表明其還可能具有酚氧化酶的催化活性。二胺氧化酶是銅蛋白家族中一種非常重要的催化蛋白酶，在組胺，腐胺和尸胺等多種胺類物質(zhì)代謝過程起非常重要的作用。在此之前，基于血藍(lán)蛋白及二胺氧化酶的電化學(xué)研究并不多見，但是研究銅蛋白對研究物種進(jìn)化及物種起源有著相當(dāng)大的幫助，同時研究血藍(lán)蛋白及二胺氧化酶生物傳感器的直接電化學(xué)行為和催化機理，有助于研究血藍(lán)蛋白及二胺氧化酶在生物體的生理作用，對醫(yī)學(xué)研究，環(huán)境檢測與保護等領(lǐng)域有很大幫助。 本論文以研究血藍(lán)蛋白及二胺氧化酶的直接電化學(xué)行為及電催化行為為目的，構(gòu)建出幾種相應(yīng)的電極。本論文的主要工作有： 1) 成功制備了納米金/纖維素季銨鹽/炭黑納米復(fù)合膜(AuNPS@QC/BC)。利用AuNPS@QC/BC納米復(fù)合膜成功固定了血藍(lán)蛋白，成功構(gòu)建出AuNPS@QC/BC/HC修飾電極。研究表明：在AuNPS@QC/BC 納米復(fù)合膜上的HC能夠?qū)崿F(xiàn)直接電化學(xué)行為，并對鄰苯二酚及對苯二酚有良好的催化活性。 2) 我們在AuNPS@QC/BC納米復(fù)合膜的基礎(chǔ)上加入了親水性的離子液體，并用于固定二胺氧化酶(DAO)，成功構(gòu)建出AuNPS@QC/BC/IL/DAO納米修飾電極。研究表明：在AuNPS@QC/BC/IL 納米復(fù)合膜上的DAO能夠?qū)崿F(xiàn)直接電化學(xué)行為，并對組胺，腐胺，尸胺等胺類物質(zhì)有良好的催化作用。 3) 我們利用炭黑(BC)/離子液體(IL)制備出碳糊電極，并成功固定了HC，構(gòu)建出BC/IL/HC修飾電極。研究表明：在BC/IL上的HC能夠?qū)崿F(xiàn)直接電化學(xué)行為，并對雙酚A有良好的催化活性。 |

Ref part 1: Cuprein widely exists in living organisms. It has a variety of physiological functions, such as oxygen carrier, electron transfer and oxidant, etc. Hemocyanin (HC) and diamine oxidase (DAO) are all copper containing proteins. HC is one of the three respiratory proteins in animal kingdom. It is a kind of multi-functional proteins acting as oxygen carrier, adjustment of the osmotic pressure in animal body, storage of the energy, and probably the catalytic activities of phenol oxidase according to the (recently) related reports. DAO is a very important catalytic protease in the family of cuprein, which plays a vital important role in metabolism process of amine substances, such as histamine, putrescine and cadaverine, etc. Surprisingly, there are few reports on electrochemical study of HC and DAO prior to this work. The study of cuprein will be of great help in the understanding of the evolution and origin of species. In the meantime, the study on the direct electrochemical behaviors and catalytic mechanisms of HC and DAO biosensors will aid us in better understanding the physiological function of HC and DAO in organisms, and be of great help in the field of medical research, environmental monitoring and protection. |

Ref part 2: In this thesis, several electrodes have been fabricated with the aim of studying the direct electrochemical behaviors and electrocatalytic functions of HC and DAO. The main contents of the thesis are as follows: 1) AuNPS@QC/BC nano-composite film has been successfully fabricated. And by immobilization of the HC on the AuNPS@QC/BC, s AuNPS@QC/BC/HC modified electrode was also successfully fabricated. The study shows that: the HC immobilized on the AuNPS@QC/BC nano-composite film can realize direct electrochemical behavior, and has good catalytic activity on catechol and hydroquinone. 2) After successful fabrication of the AuNPS@QC/BC nano-composite films, hydrophilic ionic liquid was further introduced to immobilize the DAO. In this way, a AuNPS@QC/BC/IL /DAO nano-modified electrode was successfully fabricated. The study shows that: the DAO immobilized on the AuNPS@QC/BC/IL nano-composite film can realize direct electrochemical behavior, and has good catalytic performance on amine substances, such as histamine, putrescine and cadaverine. 3) The BC/IL/HC modified electrode was successfully assembled by immobilization of the HC on the carbon paste electrode fabricated using BC/IL. The study shows that: the HC immobilized on the BC/IL can realize direct electrochemical behavior, and has good catalytic activity on bisphenol A. |
