“Intelligent nanoparticles” have been created that kill cancer cells


Scientists at the University of Surrey have now developed “smart nanoparticles”, which heat up enough to kill cancer cells, and self-regulate without damaging other tissues.

Scientists at the University of Surrey in the UK have developed “smart nanoparticles”, which heat up enough to kill cancer cells, which self-regulate and cool without damaging other tissues in the human body.

These new nanoparticles can be used soon as part of thermotherapy in the treatment of people with cancer, according to a study published in the scientific journal Nanoscale this week.

Thermotherapy has already been used for the treatment of cancer, however, it is still a complicated technique, so it is not easy to treat people without causing some damage in other cells unrelated to the problem to be treated. Tumor cells can be weakened or killed without affecting the remaining tissues if the temperature is accurately controlled at between 42 and 45 degrees Celsius.

Scientists at the Institute of Advanced Technology at the University of Surrey, together with other scientists at the Dalian University of Technology in China, have created the nanoparticles now introduced and when implanted in a thermotherapy session can induce temperatures up to 45 degrees.

The nanoparticles produced in this study are self-regulating, which means that they stop themselves from heating up when they reach above-ideal temperatures.

According to the study, these are also poorly toxic and would be very unlikely to cause injuries, only fulfilling their main function without adverse effects.

Besides being self-regulating, nanoparticles are also of low toxicity and should not cause permanent damage to the human body when used in the fight against cancer.

Ravi Silva, head of the Institute of Advanced Technology, said that this method can avoid the serious side effects of other treatments.

“It’s a very exciting development”, Ravi Silva said, referring to the possibilities of treatment with nanoparticles.
