A group of scientists from Russia and Finland have developed nanoparticles that are delivered to cancer cells and attract the effects of chemotherapy or immune cells.
“Nanoparticles with an anticancer drug were introduced into the cell culture, after which we exposed the nanoparticles to either electromagnetic or infrared irradiation. Under these conditions, the temperature of the samples increased, the polymer coating was compressed, releasing the active substance from the pores,”said Andrey Kudryavtsev from the Institute of Theoretical and Experimental Biophysics of the Russian Academy of Sciences in Pushchino.
It should be clarified that porous silicon nanoparticles are filled with chemotherapy and can be used to deliver toxic substances into tumors.
Such nanoparticles act because tumors accumulate all the "debris" of the body. In addition, due to the fact that the temperature of tumors is often higher than normal, the nanoparticles were made stable only at certain temperatures.
It should be noted that the contents of the particle are discharged at temperatures above 37 degrees Celsius. Thus, everything inside the nanoparticles manages to reach the tumors, which are then specially illuminated with the help of a laser or radio emitter.
Note that the experiments were carried out on mice. Their results showed that cancer cells are destroyed, while the impact on healthy cells is minimal. The body easily breaks down the nanoparticles after they work.
I must say that scientists continue to work to ensure that the treatment for a person is as safe and effective as possible.
