Molecular Tech For Cancer Cells

Cancer is a very dangerous for human body. It had taken away the life of so many people. When it comes to you, you can't stay happy, sadness surround you, that feeling you will die soon. Well, You definitely have to keep your faith up and just move on and do the right things, you will definitely recover from it. It requires great determination, so that you can fight back. Well, there is a good news for those who are suffering from cancer, what it's, let's have a look.  

Molecular Tech Helps Doctors Target Cancer Cells From the Inside

A group of American researchers may have revolutionized how we treat cancer, thanks to molecular technology that can target diseased cells from the inside.

The study tested the effect of nanomotors, miniscule devices that turn energy into motion, on live cells. Scientists found that they could potentially be used to deliver drugs non-invasively, or perform surgery inside of cells.

"As these nanomotors move around and bump into structures inside the cells, the live cells show internal mechanical responses that no one has seen before," Tom Mallouk, co-author of the study, said in a statement. "This research is a vivid demonstration that it may be possible to use synthetic nanomotors in new ways."

Cells ingest the nanomotors, which then move around the structures, spinning and ramming into organelles — part of a cell that has a specific function. The nanomotors, which have not been tested on human subjects yet, are controlled with ultrasonic waves. What's more, since they're made out of metal, the nanometers can be steered with magnetic forces.

The study marks the first time nanomotors have been observed in live cells. In their first incarnation 10 years ago, the nanomotors required toxic fuels to function, which meant they could not move through biological fluid; the introduction of ultrasonic waves solved this problem. In their current form, the nanomotors were tested in HeLa cells, immortal human cervical-cancer cells that are often used in research. They were most effective when a high level of ultrasonic power was used, according to Mallouk.

He added that the technology could mean big things for the future of medicine.

"One dream application of ours is Fantastic Voyage-style medicine, where nanomotors would cruise around inside the body, communicating with each other and performing various kinds of diagnoses and therapy," he said.
