Temperature-dependent and independent components of MNP_cell.

Notes: U87MG cells were incubated with Dex-MNPs or PLL-MNPs (100 μg/mL) at 4°C or 37°C. In some groups, Dex-MNPs were coincubated with PLL (3 nM) or EGCG (10 μM). Values are means ± SE (n=3). *^,◊P<0.05 compared with corresponding groups at 4°C without magnetic influence and control groups, respectively.

Abbreviations: MNP_cell, cell-associated magnetic nanoparticles; Dex, dextran; EGCG, epigallocatechin-3-gallate; MNP⁻, MNPs with negative ζ-potential; MNP⁺, MNPs with positive ζ-potential; PLL, poly-l-lysine.
