They will help create molecular machines that can deliver drugs to a specific organ.

American scientists first managed to control nanomechanisms inside a living human cell.
This is another step towards creating molecular machines, which can be used, for example, for delivery medicines to a specific internal organ.
Streamlined nanomachines moved inside the cell under exposure to pulses of ultrasonic radiation.
A group of American researchers led by Professor Tom University of Pennsylvania Malloc published an article on This is the Angewandte Chemie International Edition.
“The movement of these nanomotors inside cells, their interaction with cellular structures cause internal reactions that up so far no one has observed, “says Professor Mulluk.
Molecular surgery
Until now, such nanomechanisms have been studied only in laboratory conditions outside of living human cells.
“Autonomous movement can help these nanomotors selectively destroy the cells that surround them, such as cancer cells. We do not need all these machines to move in one direction ”

“We could use controlled nanomotors to treat cancer and other diseases by mechanical action on intracellular structures, says Professor Malluk. – Nanomotors may even perform intracellular surgery and deliver the right medicine to the right tissues. ”
Researchers have also achieved control of nanomechanisms with using magnetic fields.
They found that nanomotors can also move autonomously. and independently of each other.
“Autonomous movement can help these nanomotors selectively destroy the cells that surround them, such as cancer cells, – tells Tom Malluk. – We don’t need all these cars moved in the same direction. ”
The idea of surgery at the molecular level was first put forward the famous physicist Richard Feynman in 1959.
“You put such a miniature mechanical surgeon in artery, and he penetrates the heart and examines it. He notices faulty valve, comes up to him and cuts it off with a microscalpel, “said Feyman in a lecture given for meeting of the American Physical Society.
