"They act like some small sensors that can be inserted into the cell. For example, we measure temperature, acidity or perceive the presence of some important chemicals," explains Jan Havlík, author of the experimental part of the study of the Institute of Organic Chemistry and Biochemistry at the Academy of Sciences.
Big and dear
But the necessary crystal modification is slow and expensive. The gram in the particulate accelerator costs millions of crowns. But now Czech scientists have figured out how to simplify this demanding and costly process.
"The amount of material we produce is about one hundred to one thousand times greater than it has ever been, and this paves the way to completely different applications, such as magnetic resonance imaging," says Petr Cígler, head of the Synthetic Nanochemical Group at the Institute of Organic Chemistry and Biochemistry.
In order for nanocrystals to provide environmental information, one needs to create an error on the network. Or "star" in a particle accelerator or "new" part in a nuclear reactor.
The crystalline network of such a nanodoamant can be represented as a plateau with eggs. Each egg is as one carbon atom, and if one of these atoms can be extinguished, the optical properties of the entire material change completely. "Neutrons will blow up the core of the goddess, and the core of the fortress will spill over into the core of the lithium and heliological nucleus. These particles act as a hand that pulls the atom out of the crystal lattice," says Martin Hrubý, a scientist at the Institute of Macromolecular Chemistry.
After further processing, the crystals will be able to fluoresce. This means that it flashes almost like a sensor in the factory.
