Researchers at Lund University in Sweden claim to have developed a technique through which nanoparticles can be magnetically controlled to make tumor cells to self destruct.
Researchers led by Professor Erik Renström said that their technique was more effective in treating cancer than chemotherapy as the nanoparticles can be used to affect just the tumor cells and not healthy tissue as well.
The nanoparticles have been developed using iron oxide treated with a special form of magnetism and once they get inside the cancer cells, they begin to rotate in a way that causes the lysosomes to start destroying the cells.
"Chemotherapy can also affect healthy cells in the body, and it therefore has serious side-effects. Radiotherapy can also affect healthy tissue around the tumour. Our technique, on the other hand, is able to attack only the tumour cells", Enming Zhang, who was part of the study, said.
