Researchers were able to stop the growth of malignant tumors in experimental mice using nanoparticles that cause cancer cells to self-destruct.
For this, a team of scientists from NanyangUniversity of Technology coated 30 nm silica particles with a porous L-phenylalanine amino acid simulator. This substance is not produced in the human body, so cancer cells seek to get it.
The amino acid performs the function of bait and camouflage, thanks to which the tumor penetrates along with itandnanoparticles that stimulate excessiveproduction of reactive oxygen species, which leads to self-destruction of cancer cells, but does not harm healthy ones. This does not require the introduction of additional drugs or the activation of particles.
Laboratory experiments have shown that the Trojan horse method kills about 80% of breast, skin and stomach cancer cells.This is comparable to that of conventional chemotherapy drugs such as cisplatin.Nano tumors also significantly slow down the growth of more complex forms of tumors.
Recall that recently scientists discovered a protein that turns cancer cells into normal ones.
