A team of researchers from the University of Toronto, Canada, has created a group of micromagnetic sprays that can implant a small robot inside the human cell with extreme precision. The robot takes the form of a tiny pill and can be used to study the properties of cancer cells, which could pave the way for many possibilities for diagnosis and treatment of the disease..
Sue Sun and her engineering faculty team at the University of Toronto have been building micro-robots for nearly 20 years, which can perform various measurements of the cell, offering scientific benefits in areas such as artificial insemination. ,.
"Until now, the robot has explored the external structure of the cell and is now trying to probe the cells inside," Su-Sun said. The team has succeeded in designing a robotic system capable of examining cellular structures beneath the lenses of the electron microscope, which requires freezing, drying and cutting small parts..
Other research teams use techniques such as laser and sound waves to study cells. The technique involved the use of six magnetic poles placed at different locations around the microscope slide, researcher Xian Wang said.
The diameter of the robotic bean is 700 nm, about 100 times the diameter of the human hair, which allows its implantation in the cancer cell. Once the pearl is implanted in the cell, Wang moves it through an algorithm controlling the voltage of the magnetic poles surrounding the microscope, which forms the magnetic field in three-dimensional form in order to move the grain in the direction desired by the cell.
"Imagine it was possible to use a whole swarm of robotic granules to destroy a cancerous tumor by blocking the blood vessels that feed it or destroying it directly by mechanical amputation," he said. he declares. Adding that this technique will allow the treatment of tumor tumors resistant to chemotherapy and radiotherapy..
