In May, 2003, the power of science dawned on us to drive away the terror of SARS shrouding our souls. Many professors in our college have been commended by the national top officials because of their leading discovery of Multi-Antigenic medicine against the SARS. Seeing the weary faces of these scientific workers, I, a student who loves biology, couldn’t help outpouring my admiration to them because I hoping that someday I will become one of them. My dream of devoting myself into the Scientific Research is becoming clearer and clearer. The classmate around me reading out what I thought, I presented him with an understanding smile.

  The interest in biology is directly bound to my experience. I used to visit a famous herbalist doctor for my weakness when I was just a kid. He tried to persuade me to become a doctor every time I went there. Oddly enough, although I felt it boring to be a doctor, I became magically interested in the Ancient Chinese Secret, especially an article about westernizing the names of Chinese Medicine written by the herbalist doctor, which activated my idea of combining the Chinese traditional medicine with the modern biological technology. However, it was in senior grade 1 that I really got acquainted with the field of biological science, because I knew from newspaper that a couple graduated from Biological Science College of Wuhan University was running a biological produce company in our city after finishing their study in America. It was rare to see such a thing in my hometown at that time, particularly in the field of biological science, which inspired me a lot. Soon after that, I began my study in this field by reading the related books, which became my first choice after the College Entrance Exam.

  Finally, my good mark enabled me to enter the Biological Science Department of Wuhan University, which I was longing for. It was in the class which is only open to the excellent students that I finished my four years’ undergraduate study. Deepened by the four-year study there, my grasping to the subject pushed me out of the superficial interest to the enthusiasm in this field and presented me with the high score of GPA 3.68/4.0 on the specialty courses, thanks to my great efforts. Besides, taking advantage of the large amount of reading after class, I did a good job on seminar and presentation. Once when I prepared to do the presentation on molecular experimental class, as the chief, I got to collect large amount of files with original topics on “Systematic Evolution of Ligands by Exponential Enrichment (SELEX)” in a very short time. Our group therefore got the praise. In addition, as a rare undergraduate, I usually attended the lectures given by the foreign experts invited by our college, which are actually the required courses for post graduates. Not understand much of it as I did, I can acquaint myself with the leading world science and the effective methods in their study, which, I believe, can be helpful for my study in future.

  In the second year in University, my two schoolmates and I designed an experiment on “study in the anti-epiphyte function of natural ingredients in Huatuo Cream” with a successful application to be an extracurricular study program and got the foundation for experiment. I am the chief of the study group. By using the animalcule experimental technology, we have, on one hand, confirmed the better methods of MIC of camphor (one of the natural ingredients) and on the other, ascertained that calyx canthus oil (another natural ingredient) can work through immunity adjusting rather than anti-epiphyte. In this experiment, my capability of applying what I have learnt into practice and looking up in the literature was greatly improved, my potential was dug out and my final occupation of lying on the scientific research field was set.

  My solid foundation of this field and potential finally presented me with an opportunity to attend a scientific research program in the following days. Since April, 2005, I have attended many programs in the enzymology lab as the RA of Professor Zou Guolin. In the subject of synthesis of conducting polyaniline by the biocatalyzing of simulation enzyme, I compared the functions of different templates of polyelectrolyte, micelle and mixed micelle and confirmed the most suitable templates for High-pH polyelectrolyte and anion surface-active agent micelle. In the program of “Hemoglobin-biocatalyzed synthesis of conducting molecular complex of polyaniline and lignosulfonate”, I am mainly in charge of the synthesis part as well as attending the enactment of the experimental approach. After comparing the catalysis of Hemoglobin protein, chloridized Hemoglobin and Ferric Chloride, I found the Hb is the best. By studying the inactivation influence of various pH to Hb, I confirmed the most suitable pH, template thickness, aniline thickness, perhydrol thickness and reactivity time for Hb catalyzing reactivity, and synthesized the conducting polyanilin for the following character identification with this suitable conditions (such as the composing of chemical elements, conductivity, heat stability etc) in contrast with the traditional methods in the literature. I also contributed the thesis as the second author in this program.

  The final success shaded all the difficulties I have ever tasted during the process, leaving the valuable experience. Taking this program as an example, I have met a number of difficulties, because the main cooperator left school for his sickness, most of the work has to be done by myself independently. from the former step, (Such as the happiest reactivity pH, bottom thickness, reactivity time etc.) which required me to master the theory of the experiment and learn to analyze the experimental data as quick as possible before setting off to the next step. We need to analyze the reason whether lies in the experimental steps or in the operation in case of problems or errors. For example, when synthesizing the Hb into PANI conductive polyanilin, I found the ideal value of pH in the reactivity is 2.0, which roused my suspicion why the Hemoglobin protein, as a natural protein, can be so active in such a low pH environment. I repeated the experiment several times with carefully operating. After eliminating every possibility to the error, I looked up large amount of related files and discussed with my supervisor. It is estimated that the template LGS was synthesizing the H+, which reduced the thickness of H+ in the liquor, e.g. the pH value in the liquor around the template must be higher than 2.0. My estimation was finally proved by measuring the liquor around the template, whose pH goes really between the 4.5 and 5.5, the required range mentioned in the literature. The later experiments with other catalyzer and templates synthesizing PANI were carried out in the higher-pH environment. some of them have been completed while others are still in hand, providing me with more and more theoretical guidance and practical experience.

  As an excellent student, I am also a good basketball player apart from my good mark. I have participated in the Hubei Female College-student basketball match and got the top. From these extracurricular activities, I realized the importance of the teamwork spirit.

  I have had solid foundation in biology through the study in Wuhan University, while I realized the big gap between China and the world leaders in this field. So I determined to accept the further education abroad in order to contribute myself in the development of the domestic related enterprises, which is the only way achieve my kid dream. Meanwhile, the study in postgraduate program is critical for my future development, it is therefore very important to select a good university to continue my study. Your university is a world famous institution for higher learning with advanced equipments for scientific research, strong faculty and a good academic atmosphere, which play the critical role in the motivation of my potential. So I take your university as my first choice. My solid academic foundation, independent research ability and strong background in biological chemical industry and related subjects, coupled with my determination and strong sense of responsibility, have paved the way for me to undertake advanced studies at an institution of higher learning like yours.

在2003年5月,我们明白了科学的力量来驱赶非典的恐怖笼罩着我们的灵魂。许多在我们的大学教授一直由国家高级官员赞扬,因为他们领导发现多抗原医药抗击非典。看到疲惫的面孔,这些科学工作者,我热爱生物学的学生,忍不住流露敬佩他们,因为我希望有一天我会成为其中之一。我梦想自己投入到科研变得更加清晰和明确。我周围的同学,读出我的想法,我介绍他会心地笑了。
我的经验是直接绑定在生物学的兴趣。我用我的弱点,当我还是一个孩子,参观著名的中医。他试图说服我成为一名医生,每次我去那里。奇怪的是,虽然我觉得很无聊成为一名医生,我奇迹般地成为中国古代的秘密,尤其是一篇关于中国医药西化的名字写郎中医生,激活了我的想法,结合中国传统医学与现代生物技术。然而,这是在高二年级,我真的结识了生物科学领域的,因为我毕业于武汉大学生物科学学院,一对夫妇从报纸知道他们的研究完成后,我市运行的生物制品公司美国。难得看到这样的事情在我的家乡,在那个时候,特别是在生物科学领域,启发了我很多。不久之后,我开始了我的研究,在这一领域,通过阅读相关书籍,高考后成了我的第一选择。
最后,我的好成绩,使我进入武汉大学生物科学系,这是我很向往。这是在类,这是只开放给优秀的学生,我完成了我的四年本科学习。加深了为期四年的研究,我抓的主题推我出多大兴趣在这一领域的热情,我GPA 3.68/4.0高分专业课程,感谢我伟大的努力。此外,趁着大量阅读下课后,我做了一个很好的工作,研讨会和演示。有一次,当我准备做演示在分子实验班,作为首席“系统进化配体指数富集(SELEX ) ”在很短的时间内,我收集了大量的文件与原来的主题。因此,我们的小组得到了一致好评。此外,作为一种罕见的本科生,我通常出席讲座,由我们学院邀请外国专家,这实际上是后毕业生的必修课。了解不多的,因为我没有,我可以了解自己与世界领先的科学和有效的方法,在他们的研究中,我相信,这可以帮助我在未来的研究。
在大学的第二年,我和同学设计了一个实验“学习华佗膏”一个成功的应用程序是一个课外学习计划中的天然成分抗真菌的功能,并得到了实验基础。我是研究组的首席。通过使用微生物实验技术,我们一方面证实了MIC樟脑(天然成分之一)的更好的方法,另一方面,确定花萼眦油(另一种天然成分)可以通过免疫调节,而工作比抗真菌。在这个实验中,运用我所学付诸实践,并在文献中寻找我的能力大大提高,我的潜力被挖了出来,我趴在科研领域,最终占领设置。
我的坚实基础这一领域潜力终于送给我了一个机会,参加一项科研计划,在随后的日子。自2005年4月,我参加过很多节目的酶学实验室RA邹教授刘国林。在主题的通过模拟酶biocatalyzing导电聚苯胺的合成中,我比较了不同的聚电解质,胶束和混合胶束模板的功能,并确认最合适的高pH值的聚电解质和阴离子表面活性剂的胶束模板。 “血红蛋白biocatalyzed的导电聚苯胺的分子复合物和木质素磺酸盐”的合成方案,我主要负责合成部,以及参加制定的实验方法。比较血红素蛋白,血红蛋白和氯化氯化铁催化后,我发现血红蛋白(Hb)是最好的。通过研究不同pH值的灭活影响血红蛋白,我确定最合适的pH值,模板厚度,厚度苯胺,双氧水厚度和反应时间为HB柴油催化反应,并合成这个合适的条件(如下面的字符识别的导电聚苯胺作为构成化学元素,导电性,热稳定性等) ,与此相反,与传统的方法在文献中。我也贡献了这个计划的第二作者的论文。
最终成功的阴影在这个过程中,我曾经尝过所有的困难,留下了宝贵的经验。以这一方案作为一个例子,我曾遇到一些困难,因为离开了学校,他的病的主要合作者,大部分的工作都必须由自己独立完成。前一步, (如最幸福的反应pH值,底厚,反应时间等) ,要求我掌握的实验和理论学习下一步之前,尽可能的快的实验数据进行分析。我们需要分析的原因是否在于在实验步骤的操作问题或错误的情况下。例如,当到聚苯胺导电聚苯胺合成血红蛋白,我发现的反应中的pH值与理想值是2.0,这激起了我的怀疑为什么血红蛋白蛋白作为一种天然的蛋白质,可以是如此活跃,在这样的低pH值环境。我反复多次实验,精心操作。消除每一个可能的错误后,我看了大量相关文件,并与我的上司讨论。据估计,模板LGS在白酒中合成的H + ,从而减少了厚度的H + ,如在白酒周围的模板必须的pH值高于2.0 。我估计最终证明通过测量周围的模板,其pH值在4.5和5.5之间真的酒,在文献中提到的要求的范围内。与其他催化剂和模板合成聚苯胺以后的实验进行了在高pH环境。他们中的一些已经完成,而另一些仍然在手,给我提供了越来越多的理论指导和实践经验。
作为一个优秀的学生,我也是一名优秀的篮球运动员,除了我的好成绩。我已经参加湖北省高校女学生篮球比赛,并得到了顶部。从这些课外活动,我意识到团队精神的重要性。
在武汉大学通过研究,我有坚实的基础生物学,当我实现了中国和世界各国领导人在这一领域的差距较大。于是,我决定到国外接受进一步的教育,以促进自己的发展,国内相关的企业,这是唯一的办法实现我的孩子的梦想。同时,研究生课程的学习对我今后的发展是至关重要的,因此,它是非常重要的,选择一个好的大学继续我的研究。你的大学是一所世界著名的机构,高等院校,科研先进的生产设备,雄厚的师资力量和良好的学术氛围,从而起到的关键作用,在我的潜在动机。所以我会把你作为我的第一选择大学。我坚实的学术基础,生物化工等行业及相关学科的自主研发能力和强大的背景,再加上我的决心和强烈的责任感,铺平了道路,我在一个像你这样的机构,高等院校进行深造。
