Evidence that fibers can rupture?

Apparent catastrophic down-seam peeling back

The more I've observed the presence and behaviors of the microscopic fibers in my environment, the more I've dwelled on the question of how such materials might be utilized as a means of contaminant/bio weapons dispersal. Many have probably heard the likes of James Giordano extolling the benefits of deploying aerosolized nano-particulate matter to “get drugs where we want them to go in the brain”.

Close ups of rupture

As I ruminated on those and other loosely-veiled threats to my personal autonomy, I began to wonder what such a dispersal method might actually look and behave like. I've noted the “hitchhiker weed” properties of the fibers, as well as their remarkable static, surface tension, spooky reflexivity. Now I pose a theory: could such fibers be rolled or “baked” to encase nano-weapons/contaminants? Where, under certain environmental conditions or stimuli, they might rupture, unfold or otherwise release a payload?

I haven't seen much to support this concept. I do know there have been liquid submersion experiments to see if the fibers might be degraded or otherwise destroyed. Today I came across a fiber that appears to have undergone some kind of catastrophic rupture/coring. I've found some clip art that demonstrates the kind of rupture this fiber seems to be exhibiting:

It looks as if the fiber has split vertically down a seam, peeled back and curled under. No idea how this would happen at such a microscopic level. I've seen examples of damage to other fibers, but none this clear and extensive. Food for thought at least.
