After Guo Tailai handed over the project information to Mi Feifei, he turned around and stopped caring about these matters. The general manager Mi Feifei could handle it completely.

Guo Tailai went straight to his office and began to think about nanoneedles.

There are many materials for making nano-microneedle wafers, such as silicon materials, metal materials, polymers, etc.

Among them, single crystal silicon has excellent mechanical properties, physical anisotropy and the piezoresistive effect unique to semiconductor materials, etc., has high biocompatibility (can be used to make implantable medical device materials), has better hardness than stainless steel, and is the most commonly used production material in nanochips (microneedles).

It is not difficult for Guo Tailai to get a single crystal silicon wafer, it is just a matter of phone calls.

Although there are no single crystal silicon wafers with large diameters that can be directly produced in China, small wafers have long been produced in China.

The main thing that Guo Tailai made is to complete early animal experiments. After obtaining the detailed data, he can basically publish a paper.

When human clinical testing is allowed, another round will come and another paper will be released.

However, if you want to do animal experiments, more work is needed.

The test method is based on national standards for the evaluation of medical devices, micronuclear tests for mouse bone marrow cells, AS tests, in vitro cytotoxicity tests, in vitro mammalian cell chromosomal aberration tests, guinea pig maximum tests, and acute skin irritation tests for large white rabbits in New Zealand. These items are necessary.

In addition, the skin damage test for big white rabbits also requires a lot of experimental content.

The nanochips were applied to the skin opposite the back of the New Zealand white rabbit and removed the skin, and the skin tissue structure was observed in sections to investigate the skin damage at different working times.

On the one hand, we need to test whether the nanoneedles will break. On the other hand, we need to record the number of times that can be repeatedly applied to the skin to correspond to the test wear situation under a microscope observation.

Guo Tailai could design a series of experimental models to do animal experiments, but let Guo Tailai stare at these animals for various injections, comparison experiments and record data every day. It is purely tedious repetitive labor, and it seems that it is still somewhat unsuitable for Guo Tailai...

If Guo Tailai is an ordinary doctoral student of Professor Yang, then this job may be the daily work of Guo Tailai and other graduate students, but Guo Tailai is not an ordinary student, so for this job, you can find several collaborators.

Professor Yang’s master’s students are actually good, they are laboratories! They are professional and patient, how suitable?

Of course, Guo Tailai will definitely pay much higher than ordinary laboratory coolies. Even Guo Tailai only needs a comprehensive paper for the entire project. He only needs this paper, and the rest can be distributed to the people who work. The instructor must be Professor Yang. In this way, it can be regarded as a deeper 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 nanoneedles and certain models of extremely high biocompatible titanium alloy nanoneedles. One hundred sets of the previous ones are enough for animal experiments.

The materials were prepared on the same day after Guo Tai returned to China to go to school, which was enough for Guo Tai to use.

There is a workshop in the company that specializes in processing by Guo Tailai. Guo Tailai got in and controlled the nanorobots to work while leisurely watching TV in his mind, and passed the morning easily.

Although Guo Tailai has been running around for a while, and he seems to be busy and has not even had time to watch TV, he has not lost all the game in Tottenham, and basically all of them are watched live.

There was only one game that I couldn't catch up with the live broadcast, and I also watched the recording. In short, Tottenham's current performance is all seen in my eyes.

The team started well, Moyes' coaching level was quite excellent, the team had not been formed for a long time, and the playing style was not mature enough. Some of the young players had not yet grown to the level that Guo Tailai had expected, but the entire team had already shown a high spirit.

The Premier League has played for seven rounds. Even though the formation and cooperation have not reached the most perfect level, thanks to Ronaldo's strong personal ability and the excellent performance of several monsters from time to time, Tottenham currently ranks second with an unbeaten record of four wins, three draws and 15 points.

The first place is Arsenal, a city rival who has performed well in recent years, but Arsenal's record is five wins and two losses, and he also has 15 points. If he misses a little, he will be ranked first by Tottenham.

It is worth mentioning that Abu, who bought the team with Guo Tailai, is currently ranked third in Chelsea.

This season, Abraham 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 did perform well. He had four wins, two draws and one loss in the seventh round of the league, only one point behind the top two, and he could catch up at any time.

If Liverpool and Manchester United are closely following, the battle this season will be quite fierce and the intensity will be amazing.

But the white lilies all over the world are already very satisfied.

He ranked 13th last season, second at the beginning of this season, and only got the same points in the number one victory, but he had an unbeaten record. This result was enough to surprise Bai Baihe and others.

What was even more surprising was the performance of Da Luo and several monsters in the new transfer, which was so ecstatic that it was unbelievable.

Da Luo can definitely be said to be the best player to play with his brain now. His broken leg gave him the opportunity to rethink his style of play, and Guo Tailai's treatment brought his physical condition back to his peak.

Da Luo alone averaged 2.3 goals per game. Among them, he played a big four-game hit against Southampton in the fourth round. His wonderful performance made the opponent fans unable to help but stand up and applaud the whole game. Such performance can't satisfy Bai Baihe and others?

The only thing to say is that Bai Baihe and Tottenham players most regrettable is that the team's new boss has never appeared in the No. 1 box in Bailu Lane until the seventh round of the game.

However, Mr. T made another motorcycle in the United States that is said to be the fastest motorcycle in the world. Those who know Mr. T would know that this must be Guo Tailai's geek addiction and was playing this game that hits the limit.

In addition, there are also a large number of fans of Mr. T and admire Mr. T's design fans.

I was very happy to have such a boss who likes football but doesn’t make many mistakes anyway.

Guo Tailai is also happy. The team performs well and the players he likes perform well. Shouldn’t those who are bosses be happy?

After reviewing the time of Premier League goals, this batch of nano-microneedle wafers made of titanium alloy and monocrystalline silicon have been completed.
Chapter completed!
