| + | <p></br>OneYouthTalk x ZJU-iGEM is really an incredibly magical interaction!Synthetic Biology, characterized by creativity, curiosity, crossed interdisciplinary, will be the next revolution for the whole human beings. DNA computing, a totally different way to think out of the ‘silicon’ box, will probably be the next information computing wave! Artificial life, cloning of animals Dolly in 1996, though far not applicable, still a brand fancy angle to explore the unknown world! Human Genome Project, the post-genome project is on the road, a brand-new age is coming to us! How thrill we are to explore the rest of our world and to discover the unknown! </p> |

| + | <p></br>As iGEMers, we also discussed when immigrating to Mars, how to live and settle down as a synthetic biologist instead of a botanist. </p> |
| − | | + | <p></br>We also concerned about the freshness of our fruit (See ‘FRES(H)’, Fruit Ripeness Ethylene Sensor (Hopefully), USYD-2016). iGEM projects were and are making unprecedented possibilities to give out solutions aiming to different fields of dilemma. Combined with Synthetic Biology, ZJU-iGEM delivers the principles of biological and ethical criterion of iGEM competition to publics through OneYouthTalk. The considerations of biosafety and public engagement also invisibly lead our team to step further in our next activities for popular science! </p> |
| − | <p style="padding-left: 2em;"></br>Biosecurity is the most important and a basic consideration of our product since we chose to develop an in-vitro medical device. MDST (Zhejiang Institute of Medical Device Testing) is a supervisor department of government responsible for regulating medical device. Hence, we thought the suggestions from this department would make a great difference to our final product. Here, we applied a filed visit to their lab and interview the department charge, Lianjun Lin to consult his advice and opinions about the biosecurity and our medical device. We summarize his points of view which do make great impact on our project designing and list them below:

| − | <p style="margin-top: .6em; font-weight: bolder;"></br>• Questionaries</p>
| + | |
| − | <p style="font-weight:bold;padding-left: 2em;"></br>Q: How to promise the security of a medical diagnostic device? </p>
| + | |
| − | <p style="padding-left: 2em;"></br>A: It’s hard to define the word “security” while it related to many other concepts. The first thing you should concern about you device security is the national standard of in-vitro medical device. It represents the minimum level of safety that a product can be allowed to produce. Particularly for your device, I recommended you to focus on the basic security concerning about the Cell-Free Biosensor.</p>
| + | |
| − | <p style="font-weight:bold;padding-left: 2em;"></br>Q: How long can a medical device be reached out and scalable produced? How can we be more quickly to transform technology? </p>
| + | |
| − | <p style="padding-left: 2em;"></br>A: It depends. Usually, the process of acquiring the permission of scalable producing takes 2-3 years, including the product research period, which is according to my working experiences. But this situation is for biotech company, not for a scientific research and innovation team like you. To transform your ideas, I recommend you to think about cooperating with biotech company involving with in-vitro diagnostic device. Additionally, you should take it seriously to protect your patent right while you are sharing your ideas to others.</p>
| + | |
| − | <p style="font-weight:bold;padding-left: 2em;"></br>Q: What are your suggestions in ethics while we are designing our device?</p>
| + | |
| − | <p style="padding-left: 2em;"></br>A: Ethics consideration is as important as the security of a medical device. Nowadays, the mode of Internet plus Hospital is increasing with the concerning on the privacy disclosure. So, my suggestion here is data security while you have a further development in your device which combines with big data and internet.</p>
| + | |
| − | <p style="font-weight:bold;padding-left: 2em;"></br>Q: What do you think of our product if it can be worked out? Can you picture out your ideal in-vitro diagnostic device?</p>
| + | |
| − | <p style="padding-left: 2em;"></br>A: I think what you’re doing is great which directs me to a different way to develop in-vitro diagnostic device. If you ask me the ideal IVD from my perspective, I would love to tell you that I want to have everyone have their family physical examination at home. I think your design will possibly give out a solution for this since it is able to use types of enzymes to detect different indicators. Keep doing!</p>

| + | |
| − | <p style="margin-top: .6em; font-weight: bolder;"></br>• Overview</p> | + | |
| − | | + | |
| − |
| + | |
| − | <p></br>As an 8-year-old team, ZJU-iGEM absolutely won’t miss this biggest iGEM conference in China! This year, CCiC attracted more than 80 teams to share their projects and exchange their valuable experiences. </p>
| + | |
| − | <p style="margin-top: .6em; font-weight: bolder;"></br>• Details</p>
| + | |
| − | <p></br>Also, we presented our project and drew much attention. Then, during panel session, Xuan Wang, an experienced iGEMer, post doctor in Tsinghua University, told us that especially for the New Application Track, if we want to stand out, we must convince others by showing them a workable device. Since we were trying to construct a user-defined sensor, we considered to write a universal and detailed instruction which made it possible for everyone to construct his or her own sensor.</p> | + | |
| − | <p></br>Particularly this year, we found that there were 2 teams trying to construct cell-free systems. And we exchanged our experience on how to construct cell-free systems and shared our ideas on how to make a more distinctive ‘cell-free’ system. We all agreed that there doesn’t exist a clear definition about what is cell-free. So, we decided to have further understandings and exploring how to construct CFPS (cell-free protein synthesis) in a better way. </p> | + | |
| − | <p></br>What’s more, our inspirations burst out when we communicated with other iGEM teams. How to predict our protein docking model was one of the biggest barriers toward our project’s completion, but after talking to Peking-iGEM, we surmised that their theoretical modeling can help us out! We were also worried about lacking negative control in Curli-Fibers Expression . Fortunately, UTSC-iGEM gave us a suggestion that we can use Acetobacter xylinus to express Curli-Fibers without SpyTag so that we could set it as our negative control when demonstrating the specific binding for our reconstructed Curli-Fibers.</p>
| + | |
| − | <p></br>In iGEM HQ face-to-face session, we sit around Mrs Meagan and discussed how to make iGEM projects better and lead iGEM competition to a more influential competition. We shared suggestions one by one. Also, through this session, we understood the significance of after-iGEM, and we knew how to break a complex project into parts and accomplish them one by one. We could take just several parts with breakthroughs to Boston for the competition and finish rest parts during following years. It also helped our team to inherit team culture.</p>
| + | |
| − | <p></br>All in all, CCiC gives us a great platform to communicate, to exchange experiences and to explore ideas we haven’t come up with. Thanks, CCiC! </p>
| + | |
| − | <span class="psg_ttl psg_subtitle">Expert interview</span>
| + | |
| − | <p style="margin-top: .6em; font-weight: bolder;"></br>• Uartar Seker, Assistant Professor, Synthetic Biology Group, UNAW</p>

| − | <p></br> To ensure our curli fiber have a better conductivity, we choose to have our curli fibers enhanced with nanogold particles. But we were confused on how to choose the best concentration and the best size of nanogold particles for our experiments. So, we connected to Professor Uartar and below is his reply:"5nm gold nanoparticles should be fine. Additionally, try to do gold enhancement protocol to fill up the gaps between the particles. Actually, to increase the conductivity you my try to add cytochromes by fusion and extracellular secretion."</p> | + | |

| − | <p></br>Our project aims to detect the current at the downstream of our enzymes’ reactions. But at that time, the problem was that the current was so weak that we could not detect them in a convenient way which definitely didn’t reach our expectations. So, after we searched papers on how to enhance Curli-Fibers’ conductivity, we turned to Professor Timothy and Professor Zhong for advice.</p>
| + | |
| − | <p></br>Professor Zhong advised us to fill up all the gaps above our electrodes. He said it would be much better if we filled up with nanogold particles and he also offered us his E.coli strain (PIN4) whose endogenous CsgA was knocked off. And finally, to help us catch up with more ideas, he suggested us to take a glance at his newest paper<sup style="font-size: .8em;">[2]</sup>.</p>

| − | <p></br>Mr. Chris and ZJU-iGEM were firstly connected by After iGEM. He is an experienced iGEMer and such an earnest man. We had our first meetup in 8/8/2018, during which Mr. Chris pointed out that iGEM concerns not only the main body of your project but also the demonstration of the significance of your project. iGEMer should realize that it would never be useless to show your comprehensive considerations of your project’s Human Practice.</p>
| + | |
| − | <p></br>In the second meetup, we were confused by how to ensure the biosafety of our cell-free biosensor. He provided us his recent paper talking about how to apply the biosecurity of iGEM projects. </p>

| − | <p></br>The research and development Manager, Mrs. Juan Cui, together with her colleagues had a table meeting with us. Actually, we didn’t aware where our cell-free biosensor’s advantage lies at the very first. But after a detailed discussion, they showed much more interests in our project. They pointed out that the most intricate problems in commercial IVD is the exorbitant cost, temporally and economically.</p>
| + | |
| − | | + | |
| − | <p></br>Below are the detailed reasons:</p> | + | |
| − | <p></br>1. In their actual working process, firstly they have to test out the best enzymes matching ratios. As the enzymes are in a free state, the cluster reactions may not process easily and adequately, which makes this preliminary experiment much more complicated and highly-costed. This especially highlights the demand of our enzymes complex. </p>
| + | |
| − | <p></br>2. After getting the result of the best enzymes ratio, they will use a cluster of oxidase enzymes to detect the target substrates, and similar to the glucometer, the final result will be represented through the current transferred by the oxidase reaction. But the point is, this cluster of enzymes can only be single-used, which apparently, increase the cost of diagnosis.</p>
| + | |
| − | <p></br>What our user-defined in vitro diagnostic device can do: </p>
| + | |
| − | <p></br>1. It would be more efficiently to research how to find more in one detection. This is where our design originated – enzyme logical gates. Such gates can inform users of changes in multiple physiological indicators and make judgments about whether they are sick. By contrast, traditional detection methods require different sensors to detect different substances in sample, which requires a lot of precious time. We believe that the parallel processing capability of logic gates fits well with the high time requirements of Point of Care Testing, and it is expected to explore new possibilities in the field of first aid.</p>
| + | |
| − | | + | |
| − | <p></br>2. How to make our enzymes recycled? That’s a little bit hard but also a little excited to answer. The Curli Fiber, was first recognized as the invasion tool for bacteria, which firstly reconstructed by Harvard-iGEM 2014 as artificial biofilm, may help us out. This year, we use curli fibers with enhanced nanogold particles to covalently fix our enzyme complex on our electrode, which theoretically makes our electrode able to be recycle. And since it can be recycled, we can probably change the traditional detective methods or even lead a revolutionary among IVD.</p>

| + | |
| − | <p></br>Above is the very first communication between ZJU-China and Acon-Biotech. Later, through frequent conversations, we even get more detailed information. </p>
| + | |
| − |
| + | |
| − | <p></br>We summarize these feedbacks into serval points of view and list the corresponded adjustments to our projects.</p>
| + | |
| − | <p></br>Part I. </p>
| + | |
| − | <p></br><i>“Time matters. Time matters to personal experience. Time matters to human life.”</i></p>
| + | |
| − | <p></br>Frequent communications with Mrs. Juan Cui made us realize that the time required for detection determines whether our products are practical. To develop our product and focus on the concrete perspectives, we mainly focus on the optimization of the product response time. Especially in first aid, a one-minute delay can lead to irreversible consequences. After many rounds of brainstorming, we realized that instead of sticking to shorten the time required for a single test, we can splice our enzymes complex in-vitro with the help of Spycatcher-Spytag systems (there are other 2 orthogonal catcher-tag systems). And theoretically, this enzyme complex system can shorten the distances between each enzyme, which means this form of enzyme complex can couple cluster of enzymes’ reactions. This enzyme complex is relatively stable so that it can be applied on in vitro diagnosis.</p>

| − | <p></br>We are not content to rest on the results of the iGEM competition. We want more. Here, we summarized a developed and suitable mode for iGEM teams to build a strong connection with companies. Additionally, we are attending to transformation our project into practice and registered the part of “After iGEM”.</p>
