Scientists create nanoscale intracellular robotic surgeons




nano motors controlled inside cells

Just imagine that one day we shall be able to send microscopic robots inside our cells, where they will be able to deliver the necessary medical facilities, to conduct on-site microscopic surgery or even kill cells infected with a virus. Sounds unreal, but this opportunity we are one step closer thanks to researchers at Pennsylvania State University who have successfully been able to incorporate those “Nanomotors” inside human cells and remotely manage them within them.

Scientists describe developed robots “nanomotors” as “oblong metal particles”, which move under the influence of external ultrasonic waves. Furthermore, these robots can be controlled by the magnetic field.

For testing performance “nanomotors” scientists put them in cages HeLa, which are cancerous cells of the cervix, which are often used for various experiments. After placing “nanomotors” in cancer cells, robots influenced by short ultrasonic pulses and they began to move.

Depending on what the task required of nanorobots, they can be chosen to fit the structures inside the cell to destroy these structures by rotating around them, and hold the cell membrane rupture, literally ramming it from the inside. The last two possibilities can really come in handy in cases of therapeutic to destroy cancer cells.

Furthermore, it is noted that “Nanomotors” capable of autonomous movement, independently of each other. This possibility would have been very useful if the task for the treatment or destruction of the cells will be assigned to one of nanorobots that “nanoflota”, and it is not possible in the event that all “Nanomotors” will move in one direction at the same time.

“Our shared dream – those opportunities medicine, which were shown in the film” Fantastic Voyage “and in which” Nanomotors “will inspect inside the human body, to communicate among themselves to self-diagnose the problem and carry out their treatment,” – says Professor Tom Malluk, lead author of the study.

“There are many ways to manage such particles at such a subtle level. The desire to find them and understand how it works – that’s what drives us in this study. ”

Below you can see the video, which shows the “Nanomotors” moving inside cells.
