Chapter 1120 What Are You Doing (Part 1)

After Guo Tailai handed over the project information to Mi Feifei, he turned his head away from these matters, and Mi Feifei, the general manager, could handle them well. Guo Tailai went straight to his office and began to think about nano and micro needles.

There are many materials for making nano-microneedle wafers, such as conventional materials such as silicon materials, metal materials, and polymers. Among them, monocrystalline silicon has excellent mechanical properties, physical anisotropy, and the unique piezoresistive effect of semiconductor materials. It has high biocompatibility (can be used to make implantable medical device materials), and its hardness is better than stainless steel. It is a nanometer The most commonly used fabrication material in wafers (microneedles).

It was not difficult for Guo Tailai to get monocrystalline silicon wafers, it was just a phone call away. Although there is no direct production of large-diameter monocrystalline silicon wafers in China, small wafers have already been produced domestically. Those produced by Guo Tailai are mainly based on the completion of preliminary animal experiments. After obtaining detailed data, they can basically publish papers. When human clinical testing is allowed, there will be another round and another paper.

However, if animal experiments are to be done, more work will be required. The test method is based on the national standard for biological evaluation of medical devices, mouse bone marrow cell micronucleus test, Ames test, in vitro cytotoxicity test, in vitro mammalian cell chromosome aberration test, guinea pig maximum test, New Zealand white rabbit acute skin irritation test, these item is a must.

In addition, the white rabbit skin injury test also requires a lot of experimental content. After the nanochip was applied to the opposite side of the back of New Zealand white rabbits, the skin was removed, and the tissue structure of the skin was observed by sectioning, and the skin damage under different action times was investigated. On the one hand, it is necessary to test whether the nano-microneedle will break, and on the other hand, it is necessary to record the number of times it can be repeatedly applied to the skin under microscope observation to correspond to the test wear condition.

Guo Tailai can design a series of experimental models to do animal experiments, but it is purely tedious and repetitive labor for Guo Tailai to stare at these animals every day to do various injections and comparative experiments and record data, and it seems that it is not suitable for Guo Tailai... worth.

If Guo Tailai was an ordinary doctoral student of Professor Yang, then this job would probably be the daily work of Guo Tailai and other graduate students, but Guo Tailai is not an ordinary student, so this job can find several collaborators. Professor Yang's graduate students are actually pretty good, lab coolies! Professional and patient, how suitable?

Of course, Guo Tailai will definitely pay a much higher salary than ordinary coolies in the laboratory. Even Guo Tailai only needs one comprehensive paper for the whole project, and he only needs this one paper, and the rest can be distributed to the staff. For a living person, the instructor must be Professor Yang. In this way, it can be regarded as a more in-depth cooperation between teachers and students with Professor Yang, a good story, isn't it?

Of course, the premise of cooperation is that Guo Tailai must first produce a sufficient number of single-crystal silicon nano-microneedles and some types of highly biocompatible titanium alloy nano-microneedles. One hundred sets of one kind in the early stage is enough for animal experiments.

The materials were prepared by the company the same day after Guo Tailai returned to China to go to school, and they were enough for Guo Tailai to use. There is a workshop in the company dedicated to Guo Tailai's processing. Guo Tailai got in and controlled the nano-robots to work, while watching TV leisurely in his mind, and spent the whole morning easily.

Although Guo Tailai has been running around during this time, he seems to be so busy that he has no time to watch TV, but he didn't miss a game of Tottenham, and he basically watched all the live broadcasts. There was only one game that failed to catch up with the live broadcast, and I also watched the recording. In short, Guo Tailai can see all of Tottenham's current performance.

The team started well. Moyes' coaching level is quite good. The team has not been formed for a long time and the style of play is not mature enough. Some of the young players have not grown to the level that Guo Tailai expected, but the whole team has shown a Uplifting momentum.

The Premier League has played seven rounds, even if the formation and coordination have not yet reached the most perfect state, but relying on Ronaldinho's strong personal ability, as well as the excellent performance of several evildoers from time to time, the Tottenham team currently has four victories. With an unbeaten record of three draws and 15 points, they are ranked second. The first place is Arsenal, the arch rival in the same city who has performed well in recent years, but Arsenal's record is five wins and two losses.

It is worth mentioning that Abramovich, who bought the team with Guo Tailai, his Chelsea team is currently ranked third. This season, Abramovich directly spent 100 million pounds in the transfer operation, and hired Ancelotti, a famous coach who almost went to AC Milan, which surprised Guo Tailai. However, Ancelotti's performance is indeed outstanding. In the seven rounds of the league, he has four wins, two draws and one loss. He is only one point behind the top two and can catch up at any time. If you add Liverpool and Manchester United who follow closely behind, the battle this season is quite fierce, and the intensity is breathtaking.

The white lilies all over the world are already satisfied. It was ranked thirteenth last season, and it was ranked second at the beginning of this season. Moreover, it was only one point away from the first place in victories, but it had an undefeated record. This result was enough to surprise Bai Baihe.

What was even more surprising was the performance of Da Luo and several newly transferred monsters, which made people so ecstatic that they couldn't believe it. Ronaldo can definitely be said to be the player who can play football with his brain the most. The experience of breaking his leg gave him an opportunity to rethink his style of play, and Guo Tailai's treatment brought his physical condition back to its peak. Ronaldo alone averaged 2.3 goals per game. Among them, he scored four goals against Southampton in the fourth round. The wonderful performance made the opponent fans stand up and applaud. Such a performance , can't satisfy the white lilies?

The only thing I want to say is regret, Bai Baihe, including Tottenham players, is most regretful that the team's new boss did not appear in the No. 1 box at White Hart Lane until the seventh round.

However, Mr. T made another motorcycle in the United States that is said to be the fastest motorcycle in the world. People who know Mr. T know that this must be Guo Tailai's geek addiction, and he is playing this kind of extreme-impact motorcycle again. game. In addition, Bai Baihe also has a large number of fans of Mr. T, who admire Mr. T's design fans.

The club is very happy to have such a rich boss who likes football and doesn't criticize too much. Guo Tailai is also happy, the team is doing well, and the players he likes are also doing well. Shouldn't the boss be happy?

In the time of looking back, this batch of nano-microneedle wafers made of titanium alloy and single crystal silicon has been ready. Guo Tailai made another batch of matching syringes, then packed them all up, quickly called Professor Yang, asked Professor Yang to have lunch, and talked about these experimental arrangements by the way.
