To study the human cell, a team of researchers from the University of Toronto, Canada, created a group of micromagnetic sprays that could implant a small robot inside the cell.
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 team at the University of Toronto's Faculty of Engineering have been working on nanoparticles for nearly 20 years, who can perform various measurements of the cell, bringing scientific benefits in areas such as artificial insemination, personal medicine, etc.
"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 analyzing the cellular structures beneath the lenses of the electron microscope, which requires freezing, drying and cutting into small pieces. 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, said researcher Xian Wang, involved in the study. The diameter of the robotic bean is 700 nm, 100 times less than the diameter of the human hair, which allows its implantation in the cancer cell, according to the German press agency.
Once the cell implanted in the cell, Wang moves it with the help of an algorithm controlling the voltage of the magnetic poles surrounding the microscope, which forms the magnetic field in three-dimensional forms in order to move the grain in the desired direction within the cell.
"Imagine if it was possible to use a whole swarm of robotic cysts to destroy a cancerous tumor by filling 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.
