Graphic abstract: Dual contrasting ability of NaGd<sub>0.7</sub>Eu<sub>0.3</sub>F<sub>4</sub> nanocrystals tuned by their hydrophilic coating mode

Abstract: This work introduces non-covalent hydrophilic coating of NaGd_0.7Eu_0.3F₄ nanocrystals by polylysine (PL) and polyethyleneimine (PEI) for MRI and fluorescent imaging purposes. PL- and PEI-stabilized nanocrystals exhibit high colloidal stability, cell internalization, fluorescent contrasting of nuclei and cytoplasm, low cytotoxicity, and relaxivity (r₁= 0.17 dm³ mmol^–1 s^–1 and r₁ = 0.23 dm³ mmol^–1 s^–1).

Keywords: contrast agent, hydrophilic coating, fluoride nanoparticle, cell internalization, fluorescent imaging, polymer, Eu-based luminescence.
