Qi Min asked Zhang Zhiyong on WeChat if there were any fluorescent dyes with better stability.

Zhang Zhiyong replied after a while: "Why don't you use quantum dots?"

"What are quantum dots?" Qi Min asked.

Zhang Zhiyong did not reply immediately, but dumped her REVIEW.

It's really... hardcore. Qi Min couldn't help but murmur, do ordinary PIs really have no human rights? If a leader from the biology department asked him about fluorescent dyes, he probably wouldn't dare to dump the literature so directly.

Qi Min was reading REVIEW on the sofa. From the abstract and summary, he roughly understood what quantum dots are and what they can do. The so-called quantum dots are tiny semiconductor particles at the nanometer scale. They have been fully studied in nanotechnology. Because the electrons in them can realize the transition from the valence band to the conduction band in a quantized manner, they are called "quantum dots". Quantum dots can replace ordinary organic fluorescent dyes in biological applications, and can be approximated as point dipoles in the model, so they can be used in FRET technology.

This is very good news for Qi Min. She has used FRET to detect neuronal activity before. If she can continue to use FRET now, it will be very beneficial to the coherent logic in the article.

However, if you conduct in vivo experiments, you cannot use quantum dots made of metallic materials - they are usually biologically toxic. As for non-metallic quantum dots, Qi Min only saw peptide quantum dots in this REVIEW, and this article from earlier years shows that peptide quantum dots were still in the research stage at that time.

Qi Min asked Zhang Zhiyong on WeChat: "If used on living brain tissue, do you think peptide quantum dots are suitable?"

"It should be no problem. I have it in my laboratory, do you want it?" Zhang Zhiyong replied.

Qi Min hesitated. She had never operated quantum dots before, so the people in her laboratory had to learn from the people in Zhang Zhiyong's laboratory. But if Ke Yue is asked to study, it would be a bit overstepping. After all, Ke Yue is a doctoral student of researcher Zhou Xiaoshan. But if Wang Xin and Chen Linyou were to go, there might be something wrong with the two first-year students.

At this time, Zhang Zhiyong probably saw her delay in replying, so he sent another message: "We provide mutual assistance for free, don't worry, I won't use your communication."

Seeing him acting like this, Qi Min couldn't help but want to laugh. In her eyes, Zhang Zhiyong is a great master, and great masters disdain to rub off on other people's articles. What's more, Qi Min has already collaborated with researcher Zhou Xiaoshan on this topic. If the senior's name is to be named as the corresponding author, I'm afraid I won't be able to name Zhang Zhiyong.

But objectively speaking, if he only provides a peptide quantum dot, it really can't be said to be a name.

"Then when should I pick it up?" Qi Min asked on WeChat.

Zhang Zhiyong replied: "Even if you come to pick it up yourself, you won't know how to do it. Send me a copy of your experimental PROTOCOL first."

Qi Min sent a copy of Ke Li's PROTOCOL for brain-computer connection experiments to Zhang Zhiyong. She wasn't worried about leaking the secret. Zhang Zhiyong's chemistry laboratory could never do this.

Zhang Zhiyong did not reply for twenty minutes, and then replied: "Okay, I will prepare the samples on Tuesday, and I have to go over and teach you."

——

Zhang Zhiyong said that giving her the sample on Tuesday gave Qi Min the subconscious idea that she could skip work on Monday. And since she didn't have to go to the lab on Monday, she didn't want to think about any experiments on Sunday night.

Qi Min habitually picked up the remote control of the set-top box and just called up the movie collection when he heard Anton shouting from outside: "Come out to eat!"

Qi Min had no choice but to go out when he heard the summons, and couldn't help but sigh in her heart. In the past, when Anton asked her to eat, he always walked up to her and said it, at least with a title. Now he just shouted from a distance without a name, but Qi Min had to go over on his own initiative. She really asked for it.

But the rice was delicious. The main dish today is braised beef, the vegetarian dishes are braised eggplant with mushrooms and lettuce with garlic paste, and the snack is boiled shrimp segments, plus rock sugar pear water boiled in a new casserole.

Mimi was scooping out the pear water in the bowl with a small spoon. Anton saw it and stopped him quickly: "No, Mimi, let it cool down before drinking..."

He saw Qi Min coming out of the bedroom and said directly to her: "Go and serve the meal yourself."

In fact, he had already cooked the rice, so it was easy to serve Qi Min a bowl. However, Anton wanted to express his dissatisfaction with her in this way, and Qi Min could only accept it.

She filled the meal and sat at the table, habitually picking up the remote control and turning on the TV.

Even though the apartment she rented was small, it actually had two TVs. A normal sized TV with a set top box is in the master bedroom, and the dining room connected to the kitchen has a small TV that does not have a set top box or internet access. Even so, the small TV can still be watched.

Qi Min likes to eat nature documentaries, but when he turned on the TV, it happened to be on the animation channel. Seeing that Mimi was obviously interested in this, she gave up the idea of ​​changing the channel.

Suddenly Qi Min thought it would be a good idea to let Mimi watch Chinese TV. She would naturally have to adapt to the Chinese context when watching Chinese cartoons. After all, children cannot be stopped from watching TV.

Since there was no suitable TV program to watch, Qi Min had to focus on eating - and the dinner was really good. After eating spinach and pork liver porridge to save her numb taste buds at noon, Qi Min also felt that her taste had become much clearer when she tasted this dinner.

However, just as she reached out to cook the shrimp with her chopsticks, Anton suddenly slapped her hand with his chopsticks: "You should eat less."

"What's wrong?" Qi Min was confused.

"How many pieces have you eaten? There are only a few pieces in total." Anton said, "Save some for Mimi."

Qi Min took a look and saw that there were still a lot of shrimp segments on the plate. In her impression, Mimi couldn't eat much at all, and she ate very slowly, so before, she had always eaten as much as she wanted.

More than half a year later, Mimi may have eaten more, but it was impossible for her to be able to eat a whole plate of boiled shrimp segments all at once. The only possibility is that Anton deliberately attacked her.

Okay... let's just fight. Qi Min took back his chopsticks, picked up two lettuce stalks and took them back to chew.

Anton was finally satisfied when he saw that she could only chew green vegetables dryly. However, when she looked back, she saw Mimi secretly using a spoon to push back the lettuce in her bowl. She immediately lowered her face and criticized her: "Mimi, the food is delicious!"

Mimi immediately put the lettuce steak back into her bowl.

However, within half a minute, the little girl asked Qi Min again: "Mom, do you want to eat vegetables?"

Before Qi Min could answer, Mimi pushed her small bowl next to Qi Min's bowl and used a spoon to push the lettuce into her bowl.

Qi Min didn't know whether to laugh or cry, so he had to refuse: "Mom doesn't want to eat vegetables."

Hearing what she said, Mimi immediately said to Anton: "Mom doesn't want to eat vegetables either. Why do I have to eat?"
