Chapter 560： What do you do (on)

After Guo Tailai handed over the project information to Mi Feifei, he turned around and stopped talking about these things. The general manager of Mi Feifei could handle it well.

Guo Tailai went straight to his office and began to ponder the nano-needle.

Nano microneedle wafers are made of many materials, such as silicon materials, metal materials, and polymers.

Among them, single crystal silicon has excellent mechanical properties, physical anisotropy and unique piezoresistive effect of semiconductor materials, and has high biocompatibility (can be used for making implantable medical device materials), hardness is superior to stainless steel, and is nanometer. The most commonly used material for wafers (microneedles).

Getting a monocrystalline silicon wafer is no problem for Guo Tailai, a phone call.

Although there is no large-diameter monocrystalline silicon wafer directly produced in China, the small piece has already been made in China.

Guo Tailai's main production is to complete the preliminary animal experiment. After obtaining the detailed data, basically the paper can be published.

When the human body is allowed to undergo clinical testing, another round is another paper.

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

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, Items must be done.

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

The nano-wafer was applied to the skin of the opposite side of the New Zealand white rabbit, and the skin was removed. The skin tissue structure was observed and the skin damage was observed under different time.

On the one hand, it is necessary to test whether the nano-microneedle will break. On the other hand, under the microscope observation, the number of times that the skin can be repeatedly applied to the skin is recorded to correspond to the test wear condition.

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

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

Professor Yang’s several master's degree students are actually good, the laboratory is cool! Professional, patient, and appropriate?

Of course, Guo Tailai will definitely pay far more than the average labor of the laboratory. Even the entire project Guo Tailai only needs a comprehensive paper. As long as this paper is enough, the others can be divided. The living person, the instructor must be Professor Yang. In this way, it is also a deeper cooperation between the teacher and the student with Professor Yang. A good story, isn't it?

Of course, the premise of cooperation is that Guo Tailai must first make a sufficient number of single crystal silicon nano-micro needles and some types of biocompatible titanium alloy nano-micro needles. In the early stage, one hundred sets were enough for animal experiments.

The material was prepared by Guo Tai on the day after Guotai went back to school, enough for Guo Tai to use.

There is a workshop in the company dedicated to Guo Tailai's processing. Guo Tailai drilled in and controlled the nano-robot work, while watching TV in his mind leisurely, it was easy to pass a morning.

Although Guo Tailai has been running around this time, the seemingly busy whole people have to fly, and there is no time to watch TV. However, the game of the Spurs team is not a drop, and basically all of them are live broadcasts.

Only one failed to catch up with the live broadcast, and also watched the recording. In short, Tottenham’s current performance, Guo Tailai, is all in sight.

The team started well, Moyes' coaching level is quite good, the team is not forming long, and the style of play is not mature enough. Some of the young players have not yet grown to the level expected by Guo Tailai, but the whole team has already shown a Awesome upward momentum.

The Premier League has played seven rounds, even if the formation and cooperation have not reached the perfect state, but with the strong personal ability of Da Luo, and the performance of several enchanting times from time to time, the Spurs team currently has four wins. Sanping's unbeaten record of 15 points ranked second.

The first place is Arsenal, the best rival in the same city in recent years, but Arsenal's record is five wins and two losses, the same 15 points, a slight loss, will be the first to be beaten by the Spurs.

It is worth mentioning that, together with Guo Tailai to buy the team's Abu, his Chelsea team is currently ranked third.

This season, Abu directly smashed 100 million pounds in the transfer operation, and hired Ancelotti, who almost went to the coach of AC Milan, which made Guo Tailai quite surprised.

However, Ancelotti is indeed outstanding. The league has seven rounds, four wins, two draws and one loss. It is only one point worse than the top two and can catch up at any time.

If coupled with Liverpool and Manchester United, the battle of this season is quite fierce, and the intensity is amazing.

The white lilies of the world are already satisfied.

Ranked 13th last season, ranked second in the beginning of the season, and the first place is only the same score in the victory, but has an unbeaten record, this is enough to make the white lily surprise.

Even more surprising is the performance of Da Luo and the enchanting performance of several new transfers, which is ecstatic and unbelievable.

Da Luo can definitely be said to be the player who will use his brain to play the ball. The experience of broken legs has given him an opportunity to rethink the style of the ball, and Guo Tailai's treatment has brought his physical condition back to the peak.

It’s just a big man, and he averaged 2.3 goals per game. The fourth round of Southampton also played a big four, and the wonderful performance made the opponent fans can’t help but stand up and applaud. Still can't make the white lilies satisfied?

The only thing to say is regrettable. The white lilies, including the Spurs players, are most regrettable. The new boss of the team has been in the seventh round and has not appeared in the No. 1 box in Bailu Lane.

However, Mr. T made another one in the United States that is said to be the fastest motorcycle in the world. People who know Mr. T know that this is definitely the geek addiction of Guo Tailai, and he is playing this kind of impact limit. game.

Along with the white lily, there are a large number of fans of Mr. T, who admire Mr. T’s design fans.

The boss who has such a lot of gold and loves football and not much arrogant, is very happy in the club.

Guo Tailai is also happy, the team is performing well, and the players who like it also perform well. Shouldn’t the boss be happy?

In reviewing the highlights of the Premier League, the nano-micro-needle wafers made of titanium and monocrystalline silicon have been completed.

Guo Tailai made another batch of syringes for use, and then packed them all, and quickly called Professor Yang. Mr. Yang had lunch together, and by the way, talked about these experimental arrangements.
