Nanorobot with hidden weapon kills cancer cells

Looks like gold nanoparticles kill glioblastoma colon cancer: https://news.ycombinator.com/item?id=40819864 :

>> He emphasizes, "Any scientist can already use our model at the design stage of their own research to instantly narrow down the number of nanoparticle variants requiring experimental verification."

Magnets, nano robots, NIRS targeting,

Not an expert but it seems acid is not specific enough. There are acidic organs like the stomach but also the vagina. I wonder if the nano robots would then attack stomach and vagina cells.

This said, I am pleasantly surprised that nano robots, a scifi idea, are actively researched and tested. As a child I watched a French TV scifi animation series which showed people and their vessel minified and injected into a human body. Now finally it seems this future has started? I hope it is a good start.

It relies on acid? Try https://en.wikipedia.org/wiki/Helicobacter_pylori too, please.

In the long term I expect engineering to outperform evolution in the same way that mathematics allowed humans to establish such a practical lead that we're almost in a different class to animals. It'll be interesting to see how quickly and how lopsided the advantage is over cells if nanorobots take off.
