I'm wondering because drug delivery and nanotech will be my primary area of research. Right now we have a professor at my school that has made breakthroughs in drug delivery across the mucosa in the lung with nanonparticles. Also, there is hordes of research with regards to DNA/RNA/drug delivery with nanoparticles that almost mimic the behavior of viruses, but since they are synthetic, are evading the immune system. Would this be dangerous technology? I mean, it sounds extremely easy to weaponize it. Just package a nefarious strand of DNA/RNA into a nanoparticle delivery system that can easily be delivered into the lungs by inhalation and you could basically have airborne ebola, hanta, or whatever other nefarious piece of DNA you could package into a nanoparticle delivery system. Not only would it be airborne, it would be able to easily evade the body's immune system. So what would stop someone from weaponizing any of the nanoparticle technology that is being heavily researched?
