While this article discussed Bill Gate’s funding of nanoparticles and the potential of “sweat-triggered vaccine delivery” systems; and how such systems might covertly be used to spray nanoparticles to penetrate humans’ skin to administer vaccines; Not considered are the risks terrorists could potentially adopt nanoparticle delivery systems as a weapon of mass destruction to harm or destroy civilian populations. Not Addressed: in the past 50-years several vaccines have been discovered defective and recalled; what might happen should a government covertly spay millions of people with a harmful nanoparticle vaccine; how would a government explain it; would a government even admit to it? Who would pay medical costs of people injured by a covert nanoparticles vaccine?

Importantly, governments and terrorists might adopt nanoparticles to covertly spray and penetrate the skin of civilian populations with biological or chemical agents that cause terminal illnesses or delayed death in terms of days, months or years. It might be possible for a government to spray civilian populations with benign nanoparticles—then subsequently years later spray from a plane or other means a (binary biological agent) to interact in people pre-exposed to earlier spaying of nanoparticles; a corrupt government could have power over life and death deciding which people they wanted removed before the second spaying…the binary agent. Covertly spaying nanoparticles could be used as a weapon by a government to eliminate civilian populations deemed a political or economic burden or for that matter any country. (Covert spaying or other delivery) of nanoparticles to penetrate human beings, animals or on any product foreseeable or intended for human or animal consumption should be considered Terrorism.
