title: Tailoring bifunctional hybrid organic–inorganic nanoadsorbents by the choice of functional layer composition probed by adsorption of Cu<sup>2+</sup> ions
abstract: Spherical silica particles with bifunctional (≡Si(CH<sub>2</sub>)<sub>3</sub>NH<sub>2</sub>/≡SiCH<sub>3</sub>, ≡Si(CH<sub>2</sub>)<sub>3</sub>NH<sub>2</sub>/≡Si(CH<sub>2</sub>)<sub>2</sub>(CF<sub>2</sub>)<sub>5</sub>CF<sub>3</sub>) surface layers were produced by a one-step approach using a modified Stöber method in three-component alkoxysilane systems, resulting in greatly increased contents of functional components. The content of functional groups and thermal stability of the surface layers w
