Analysis of descriptors used most frequently in kNN-QSAR models of 109 MNPs. (a) Average descriptor values in MNPs with highest and lowest PaCa2 cellular uptake. (b) Example of a lipophilicity related descriptor (GCUT_SLOGP_0), which significantly discriminates between nanoparticles with highest and lowest PaCa2 cellular uptake.
