If I could visualize nanoparticles, I'd think of them as crime bosses because apparently they can mess with DNA without ever having direct interaction. Like a true godfather, a nanoparticle commands obedient molecules to do the dirty work.
Researchers aren't entirely sure just how the whole process works, but they have observed the resulting damage of nanoparticles signaling a hit on DNA. They suspect that the events might go differently in situations other than a lab test and that the interaction could be used to deliver medicine or target cancer cells. Either that or further nanoparticle deaths.
While they sort out the details, I'm just gonna stick to being a bit scared that I'll get a package of fish if I upset any nanoparticles anyway.[Pop Sci]
