Target-Controlled Redox Reaction and Ru(II) Release of a Smart Metal–Organic Framework Nanomaterial for Highly Sensitive Ratiometric Homogeneous Electroanalysis of Cadmium(II)

Inorganic Chemistry, Год журнала: 2023, Номер 62(42), С. 17425 - 17432

Опубликована: Окт. 9, 2023

In this work, a highly sensitive ratiometric homogeneous electroanalysis (HEA) strategy of cadmium(II) (Cd2+) was proposed via Cd2+-controlled redox reaction and Ru(bpy)32+ (Ru(II)) release from smart metal-organic framework (MOF) nanomaterial. For achieving purpose, Ru(II) entrapped ingeniously into the pores an MOF material (UiO-66-NH2) subsequently gated by double-strand hybrids Cd2+-aptamer (Apt) its complementary sequences (CP) to form novel nanomaterial (denoted as Ru@UiO-66-NH2); meanwhile, Fe(III) selected additional probe present in electrolyte facilitate reaction: + → Fe(II) Ru(III). Owing strong binding effect Cd2+ target specific Apt, Apt-CP hybridization at Ru@UiO-66-NH2 would be destroyed presence Cd2+, related Apt further induced away nanomaterial, leading opening gate Ru(II). Meanwhile, released quickly oxidized chemically On basis generated Ru(III) consumed Fe(III), ratio reduction currents between exhibits enhancement it is dependent on level Cd2+; thus, HEA then designed. Under optimal conditions, sensor shows wide linearity ranging 10.0 pM 500.0 nM, achieved detection limit 3.3 pM. The as-designed not only offers unique idea realize simple assay for but also possesses significant potential effective tool introduced other analysis just altering Apt.
