A team of researchers from the University of Toronto in Canada has created a group of micromagnetic "tweezers" capable of planting a small robot inside the human cell with extreme precision.
The robot takes the form of a small pill and can be used to study the properties of cancer cells, thus paving the way for the development of diagnoses and treatment of the disease. The new robot can perform different measurements of the cell, which has scientific benefits in areas such as artificial insemination, personal medicine, and so on.
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 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.
"Imagine if it was possible to use a complete swarm of robotic cysts to destroy a cancerous tumor by blocking the blood vessels that feed it or destroying it directly by mechanical amputation," Sun said.
