Not sure if you've ran across this

"Sodium citrate has been proposed to dissolve ionically cross-linked hydrogels by exchanging calcium ions with monovalent cations and sodium ions. Furthermore, ethylenediaminetetraacetic acid (EDTA), a chelating agent that binds mostly bivalent ions (calcium), has been introduced to dissolve hydrogels"

Good question. You do not expend all these resources to no perceived or expected benefit. I’m sure it has been studied either in animals or possibly small human populations. The technology is being scaled up. Self assembly may not be perfected yet. Too many variables in large populations. Assessments are done in macro until self assembly results in measurable or workable devices. Whatever that may be. Too bad about the collateral damage the just happens to cull the heard along the path of devices to corral the herd. Those remaining will have a tolerance to the technology and more robust solutions can then be developed.

Being that it is so ubiquitous they probably already have countermeasures while development is ongoing. It’s up to us to find those.
