-					At the beginning of the experiment, team LZU-HS-Pro-A helped us prepare consumables, such as ddH2O, 0.1M CaCl2, and a liquid culture medium. Since our experiments are similar in several parts, we can save time by reducing repetitive procedures. Similarly, they had our plasmid extraction done, so we did not have to spend extra time there. During the experiment, the problem they faced is the lack of materials. They had an inefficient AMP to make AMP antibiotic mother solution, and they were stuck due to this limitation. At that time, our team gave them the excess AMP that we own to help them continue. We try our best to solve all the issues we met and try to experiment as effectively as possible.

Then, when balancing the centrifuge, we checked each other’s balance again for safety concerns.

-					Firstly, and most importantly, since we both use cell surface display technology in our projects, we can help each other technically. In the earlier phase, the problem we faced was choosing a proper anchor protein, which is an essential protein used in cell surface display technology. This is a critical section of the projects for our three teams, but we have no idea which kind of protein can be used, so during our first online meeting, we set up a detailed plan for our projects’ future progress.
+					&emsp;&emsp;Firstly, and most importantly, since we both use cell surface display technology in our projects, we can help each other technically. In the earlier phase, the problem we faced was choosing a proper anchor protein, which is an essential protein used in cell surface display technology. This is a critical section of the projects for our three teams, but we have no idea which kind of protein can be used, so during our first online meeting, we set up a detailed plan for our projects’ future progress.

 					</div>
-					<div>We hope that our project will inspire future iGEM teams to create more efficient, effective, and convenient detection methods and even suitable substitues. It is believed that, with progressing research into BPA's health hazards, extensive detection methods invented, and possible subsitution found, the threat of BPA can utimately be eliminated. </div>
-					<div>Moreover, our team built an enzyme based electrochemical biosensor, which feature cell-surface display, a technology that express target proteins on cell membrane . The high specificity, stability, and cost-effectiveness it displayed can be used for future teams while constructing biosensors. </div>
-					<div>The enzyme we used is tyrosinase. "tyrosinase is an oxidase that oxidizes bisphenol A to catechol. After this, catechol can still be oxidized by bisphenol to o-quinone. O-quinone is an electrochemically active substance that generates electrical energy to detect BPA" (4). But this basic information alone does not reveal the true properties of this amazing chemical. But as our ICUnited team dug deeper, we found that. Tyrosinase can exhibit high reactivity and selectivity. When chemically attached to the electrodes, it becomes renewable with little loss. They are more effective and adaptable than any other substance. We think this finding will be A great tool for future teams to use in experiments related to BPA.</div>

The main reason why we choose this topic is that in modern society, bisphenol A has become one of the most widely used industrial compounds in the world due to its colorless, transparent, durable, impact resistance and other excellent properties. It is often used in canned food, beverage packaging, milk bottles, water bottles, eyeglasses and other places closely related to people. So when people use water or food that has been exposed to BPA on A daily basis, the BPA that seeps into the food can enter the body. A small number doesn't make much difference to humans, but if the number increases, a number of potential risks will emerge, such as "decreased sperm count, decreased fertility, increased prostate growth...”.

The monitoring of environmental contaminants is crucial for controlling pollution. Traditional physicochemical detection methods focus on high-performance technologies such as ultraviolet spectrometry and liquid chromatography. These approaches provide accurate analysis of environmental samples and have high sensitivity. However, they require costly analytical apparatus and are time-consuming, which makes them unsuitable for in-situ and rapid analysis.
