Theory 19/Nanoscale/Nanoplastics
Nanoplastic Entry Is a Pore Ratio
The claim
Whether nanoplastic particles enter a cell is set by the ratio of particle size to membrane pore size, not by concentration.
01Mechanism
Entry requires passage through or deformation of a pore; particles above the ratio depend on endocytosis and its kinetics.
02Prediction
Entry should track the size ratio.
03Refutation
Entry tracking concentration would remove the size threshold.
