New nanoscale machines can kill cancer cells in minutes

Fifty thousand of these nanoscale devices are lined up just the same width as a human hair.

Scientists have successfully developed tiny nanoscale machines capable of drilling into cancer cells and destroying them in an instant.

Last year's Nobel Prize in Chemistry was awarded to three scientists who discovered how to make nanoscale devices by knitting atoms together into chains. To publish a paper in Natural magazine, scientists have created a small number of nano machines. When activated by light, the virus attacked the membrane of the designated cells and destroyed them.

Three scientists won the Nobel Prize in Chemistry in 2016.

Nano machines are produced so small that when lining up 50 thousand machines side by side, they are only as thick as a hair shaft. Each machine is designed to identify the type of protein that is in the predetermined cells, and thus find the object to remove.

The turning point in nanoscale machine technology opens up many new doors in Medicine.

Once a light source is added, they rotate in place at 3 million revolutions per second. This spinning force is enough to pierce into the cell. When there is no light, the nano machine only finds the designated molecule and stays on the cell surface.

When 'freezing' the machine in a disc containing human kidney cells, the nano machine punctured the cell membrane removed them in just a few minutes. The same thing happened when the research team experimented with nanoparticles on prostate cancer cells.

Cells puncture cell membranes and eradicate designated protein-containing cells.

This technology is still in the development stage and has only been tested with the scale of micro-organ and fish apparatus. But in the future, these nanoscale machines can be used to transport drugs accurately to cells that need to treat or even eradicate cancer cells and create new treatments for many. fatal disease.
