Back in January, I reported on a new nemesis for cancer – nanorobots.
As the name suggests, these ingenious devices are a cutting-edge combination of robotics and nanotechnology. The end result is miniscule, drug-carrying nanorobots that roam the body, seeking out cancerous cells with deadly accurate precision and then destroying them directly at the source.
Well, the nanorobot has an equally potent twin brother – nanoparticles.
And the science behind these destroyers is equally brilliant and fascinating…
How “Wiggling” Nanoparticles Force Out Cancer
In laboratory experiments, scientists have managed to kill cancer cells using highly intelligent nanoparticles.
The Lund University team’s process involves positioning nanoparticles above cancerous cells, then “wiggling” them inside the cells, where they attach themselves to lysosomes that help wipe out cancerous material.
By itself, though, this doesn’t complete the cancer-killing mission; it’s merely the setup.
The “destroy” part comes from Lund’s partners at Elektronic Stetter, who’ve figured out how to apply a magnetic charge to these iron oxide nanoparticles.
In doing so, they make the lysosome membrane porous, which allows damaging, cancerous enzymes to escape, and triggers a chain reaction that also nukes other cancerous cells.
This method of magnetically “rolling” the nanoparticles, in order to make cancer cells “self-destruct” is an important new breakthrough. That’s because previous attempts using magnetically charged nanoparticles required heat to make them work – a process that caused healthy cells to be damaged, too.
But Enmin Zhang, a scientist overseeing the project at Lund University, says his team’s method doesn’t use heat. And not only is it unique, it’s also safer and more effective than radiotherapy and chemotherapy, as it gets the job done without harming healthy cells: “We use an external magnetic field to apply control in a very specific manner. This is something that chemotherapy cannot do. It’s a controllable treatment process.”
Here’s a closer look at how it works…
This is just one of many research projects currently in the works around the world in the highly specialized field of nanotechnology. And it’s a perfect fit for infiltrating deep into areas of the body ravaged by cancer and where the virus is prone to spread before doctors or conventional treatment can attack it in time.
As trials continue, both Zhang and Lund University’s partners at Elektronic Stetter, ultimately believe that their work is one of the latest efforts to create a much-needed non-invasive cancer treatment.
