Enamed nanodiamonds help treat cancer. Thanks to Czech scientists, their production will be cheap iROZHLAS



Czech scientists have found a method of cheap production of irradiated nanodiamonds and other materials useful for highly sensitive diagnostics of diseases, including cancerous diseases. A scientific journal Nature Communications published the article of scientists led by Petr Cígler of the Institute of Organic Chemistry and Biochemistry of the Academy of Sciences of the Czech Republic and Martin Hrubý of the Institute of Macromolecular Chemistry.

Nanodiamonds, which are synthetically synthesized from graphite at high pressures and temperatures, are used in diagnostics and nanomedicine. However, pure nanodiamond is not usable for this purpose, so its crystalline grid must first be damaged in order to cause specific optical readability.


The first Nobel Prize is the winner. Scientists Allison and Hondo have obtained it for the development of a special cancer treatment

Damage is most often caused by irradiation of the nanodiamond with fast ions in particle accelerators, but it is a costly and not very effective method, since it does not allow the production of more material. A team of scientists has published a new method of irradiation in a nuclear reactor that is cheaper.

They have exploited the way in which atomized boron atoms are broken down in the neutron radiation in the reactor for light and fast flying ions of helium and lithium, which have the same effect of controlled crystal formation as the same ions produced by the accelerator.

However, the shower has a high density and much more material can be irradiated in the reactor, so it is cheaper to make tens of grams of rare nanomaterials at a price of more than a thousand times more than radiation in accelerators.

This year's prestigious grant was awarded to five young Czech scientists. It is the best result in 10 years

Additionally, the method is not only successful for the creation of nanodiamond grating, but also for silicon carbide. According to scientists, it could serve universally on a large scale.

Nanomedicine is defined as monitoring, repairing, constructing and controlling the human biological system at the molecular level using nanoscience and nanostructures.

It is a further developmental stage in the field of molecular medicine and biotechnology. Nanotechnology generally deals with objects of the order of magnitude in nanometers, ten to minus nine meters.
