A team of researchers has found a way to make a biosynthesis of small gold nanoparticles in cancer cells, to help with X-ray imaging and even to destroy them.
It would not be the first time scientists have used gold nanoparticles to fight cancer growth. But until now, the techniques were limited by the way they were introduced into them. Some methods have caused particles to block on peptides or even white blood cells, according to the New Atlas.
However, this new technique allows the biosynthesis of gold nanoparticles directly inside cancer cells, a “very promising approach to drug administration,” according to Dipanjan Pan, a professor at the University of Maryland, Baltimore County. He is also the co-author of a paper on the technique, published in the journal Nature Communications last week.
Thus, once injected into cancer cells, gold nanoparticles began to act in cancer cells during a laboratory experiment, a process that lasted only a few minutes. “We have developed a unique system in which gold nanoparticles are reduced by cellular biomolecules and they are able to retain their functionality, including the ability to guide the remaining group to the nucleus,” he explained. the process in a statement.
Then, scientists demonstrated the same approach inside a tumor of something, before destroying it by heating nanoparticles with a laser, a process known as “curing”. photothermalÃ¢ â¬.
Pan also said that the most challenging research before us will be finding new ways to produce these uncompromisingly reproducible particles and evaluating how nanoparticles will affect human health. long term.
