Graphene-oxide-loaded superparamagnetic iron oxide nanoparticles for ultrasensitive electrocatalytic detection of microRNA
Abstract
We report the electrocatalytic activity of a new class of superparamagnetic nanoparticles, graphene-oxide-loaded iron oxide (GO/IO hybrid material), towards the reduction of ruthenium hexaammine(III) chloride (Ru(NH3)6]<sup>3+</sup>, RuHex). Leveraging the electrocatalytic activity of the GO/IO hybrid material and the signal enhancement capacity of [Ru(NH<sub>3</sub>)<sub>6</sub>]<sup>3+</sup>/[Fe(CN)<sub>6</sub>]<sup>3−</sup> in an electrocatalytic cycle, an ultrasensitive and specific electrochemical sensor was developed for the detection of cancer-related microRNA (miRNA). Using the direct affinity interaction between RNA and graphene oxide, magnetically isolated and purified target miRNA were directly adsorbed onto a screen-printed electrode modified with the GO/IO hybrid material. The detection was enabled by chronocoulometric (CC) readout of charge-compensating [Ru(NH<sub>3</sub>)<sub>6</sub>]<sup>3+</sup> followed by an enhancement in CC charge display through the Ru(NH<sub>3</sub>)<sub>6</sub>]<sup>3+</sup>/[Fe(CN)<sub>6</sub>]<sup>3− </sup>system. We demonstrate an excellent limit of detection of 1.0 fM by accurately detecting miR-21 in synthetic samples and showcase its clinical utility in ovarian cancer cell lines with high sensitivity (ten cells) and good reproducibility (% RSD=<5 %, for <i>n</i>=3).
