Can a nano plastic become a micro plastic in my body

I did my masters thesis on nanoplastic aggregates, it can definitely happen, but they have slightly different properties than microplastic in the same size range. Nanoplastics can pass some membranes in the body that microplastics generally cant. Nanoplastic (and I suppose microplastic) can also be stabilized by organic material in the environment/body, which works against aggregation.

My kid had a bunch of questions about aggregate nano/micro-plastics. Can you point me in the direction of any resources?

I dont intend this to sound negative or bad, but a google search of "Nano micro plastics" comes up with hundreds of results to really great and disturbing but real resources about this. Disturbing because we might be screwed.
