Oh I have no idea, unfortunately. The fact that they even have embryonic medications and treatments these days is amazing.

If you read what I typed earlier as "medication for treating microplastic complications", it was intended as "medication based on using microplastics as a key ingredient"

It is in extremely early theoretical testing, it seems? https://www.science.org/doi/abs/10.1126/science.abm5551 The OP paper seems to be suggesting caution on this line of study.

We already have many non plastic nanoparticle medications, and the number is accelerating with technology.
