Nanomotors, not nanomachines. In summary they made nanomotors that can stick to cells, and fuck them up by spinning around. They're probably not that specific either.


Wew, we've made so much progress in molecular machines that we're now at the level of Hero's steam engine.

From https://www.sciencedaily.com/releases/2017/08/170830132217.htm:

"The Rice lab created 10 variants, including motor-bearing molecules in several sizes and peptide-carrying nanomachines designed to target specific cells for death, as well as control molecules identical to the other nanomachines but without motors."

and

"The Pal lab at Durham tested motors on live cells, including human prostate cancer cells. Experiments showed that without an ultraviolet trigger, motors could locate specific cells of interest but stayed on the targeted cells' surface and were unable to drill into the cells. When triggered, however, the motors rapidly drilled through the membranes.

Test motors designed to target prostate cancer cells broke through their membranes from outside and killed them within one to three minutes of activation, Pal said. Videos of the cells showed increased blebbing -- bubbling of the membrane -- within minutes after activation.

Smaller molecular motors were harder to track but proved better at getting into cells quickly upon ultraviolet activation, disrupting their membranes and killing them. Motorless control molecules were unable to kill cells upon ultraviolet exposure, which eliminated thermal absorption of ultraviolet light as the cause of disruption, according to the researchers."

They are able to target specific cells.

sure, as long as only those specific cells express a certain binding site.

Still, you can barely call the damn thing a nanomachine.

A news story about a miracle cure for cancer? That's a first, looks like cancer's a thing of the past now, that's a relief, gonna go throw out my sunscreen and smoke some marlboros.

Hooray! And it'll only be about 120 more years until they're developed into something that can actually work in humans!
