Honey, I Shrunk the Lab: Emerging Microfluidics Technology and Its Implications for Chemical, Biological, and Nuclear Weapons [open pdf - 300KB]
From the Document: "[I]f Syria were to covertly restart the chemical weapons program it committed to abolishing in 2013 [...] it might take advantage of microfluidics, an emerging field with various national security implications. Microfluidic technologies could not only enable Syria's efforts, but also complicate international attempts to stop them, just as it could enable other states, and eventually terrorists, to produce their own chemical weapons. At the same time, these technologies also have the potential to aid efforts to defend against such threats."
