The team has developed “the first robotic system of fully autonomous DNA”
A group of researchers were scheduled to nanorobots to seek and destroy tumors by cutting their blood supply. The research has been carried out by experts from the State University of Arizona (USA) together with other National Center of Nanoscience and Technology of the Chinese Academy of Sciences
The director of the Center for Molecular Design of the University of Arizona, Hao Yan, indicated that the team has developed “the first robotic system of fully autonomous DNA” in cancer therapies and that technology “is a strategy that can be used for many types of cancer.”
The challenges to make progress in nanomedicine have been complex, scientists have wanted to design, build and control the nanobots to seek and destroy cancerous tumors without harming healthy cells.
The research group has succeeded in overcoming this obstacle using a strategy with which to select and reduce the tumor with a job that began five years ago.
To do this, cut the blood supply to the tumor inducing the coagulation of the blood with a robotic system fully programmable.
“These nanorobots can be programd to carry loads of molecules and cause blockage of blood supply of tumors, which can result in the death of the tissues, and in the reduction of the tumor,” said another of the experts and Fushou Ding.
The scientists injected in mice human cancer cells to induce the growth of aggressive tumor and when this increased in size, the nanorobots that proved to be safe and effective in the reduction of the tumor.
No changes were detected evidence that these nanorobots from spreading to the brain, where they could cause unwanted side effects, such as a stroke.
The treatment, according to the study, blocking the blood supply to the tumor and gender, in 24 hours, without causing damage to the no effect on healthy tissues.
Hao Yan stressed that “in the mouse model of melanoma, the nanorobot not only affected the main tumor, but also prevented the formation of metastasis, showing a promising therapeutic potential.”
