Herein, we reported a simple synthesis of monodisperse, uniform, and highly crystalline MnTiO 3 nanodiscs and their application as a new promising catalyst for H 2 O 2 -mediated oxidative degradation. Unlike previously reported method that required use of preprepared titanate nanowires as precursor, this synthesis of well-defined MnTiO 3 nanodiscs was implemented through a one-pot homogeneous reaction process under hydrothermal conditions. The growth of MnTiO 3 nanodiscs was revealed to follow the nucleation− dissolution−recrystallization mechanism, and the (001) crystal facet was preferentially exposed since it was the densest and most thermodynamically stable. Two-dimensional flat plane of the MnTiO 3 nanodiscs helped minimize the diffusion pathway of guest molecules, thus allowing a fast mass transport. Moreover, the Mn(II)-rich structure and distinct crystallinity endowed MnTiO 3 nanodiscs with high activity and stability. In the presence of H 2 O 2 , MnTiO 3 nanodiscs exhibited a high efficiency in catalytic decomposition of a series of organic pollutants with an excellent recycling durability. About 98.6% of methylene blue was catalytically decomposed within 20 min at 30 °C. When the reaction temperature increased to 40 °C, only 8 min was required. Comparative investigation further confirmed the superior catalytic performance of MnTiO 3 nanodiscs, with about 2 times higher removal efficiency than reported under similar conditions.

“…11 Manganese titanate (MnTiO 3 ) is one of the important perovskites due to the excellent stability, good sensitivity, selectivity and temperature coefficient almost near zero, can be effectively used for the determination of AMP. In earlier reports, Ansari et al 12 used manganese doped titanium oxide composite for the electrochemical sensing of hydroquinone with a detection limit of 7.5 μM and Ghoreishi et al 13 used manganese titanate carbon paste electrode for the electrochemical detection of captopril with a detection limit of 1.6 μM.…”

In this paper, we report the synthesis of MnTiO3 nanoparticles employing a simple, eco‐friendly and low‐cost hydrothermal method. The properties of MnTiO3 nanoparticles were analysed by XRD, FTIR, FE‐SEM, TEM and thermogravimetric analysis (TGA). Structural properties revealed that the MnTiO3 have rhombohedral phase. Morphological studies revealed that the synthesised sample has granular‐like structure. FTIR technique confirmed the formation of MnTiO3 nanoparticles. TGA shows that the as synthesised sample is thermally more stable. The electrochemical detection of acetaminophen (AMP) by using nano‐perovskite‐type manganese titanate (MnTiO3)‐modified glassy carbon electrode is reported. The conductive behaviour of MnTiO3‐modified glassy carbon electrode (MnTiO3/GCE) was confirmed by cyclic voltammetry (CV). Differential pulse voltammetry (DPV) was employed for the detection of AMP. DPV technique showed a comparatively lower detection potential with a higher peak response towards AMP sensing with a linear range of 1.3 to 13.8 μM. The limit of detection and sensitivity were found 1.26 μM and 36.22 μA μM−1 m−2, respectively. Moreover, the modified electrode also demonstrated better repeatability, reproducibility and higher stability, hence used for the analysis of AMP in pharmaceutical and human serum samples with good recoveries. Electrochemical properties showed that the MnTiO3 perovskite has specific capacitance 357.2 F g−1 revealing its charge storing ability.

“…For protein biomarker detection, aptamers have been used as alternatives to antibodies because of their specific target affinity, convenient chemical synthesis, thermal stability, and simple discovery . Electrochemical impedance spectroscopy (EIS) is an advantageous method for the investigation of interactions between aptamers and target molecules, as it requires no labeling, is inexpensive, and displays high sensitivity and selectivity . To enhance the detection ability of an EIS aptasensor with an enlarged active surface, electrochemical deposition of gold nanoparticles (GNPs) on the electrode surface has been reported .…”

A Novel Eosinophilia Diagnostics Using Label‐free Impedimetric Aptasensor for Soluble Interleukin‐5 Receptor Alpha

Recently, interleukin‐5 receptor alpha (IL‐5RA) was reported to be a key surface molecule in the regulation of eosinophil proliferation. In this study, a highly sensitive aptamer for IL‐5RA was applied to an electrochemical biosensor. The rod‐shaped gold electrodes with circular gold surface were used. The aptasensor specifically detected membrane‐bound IL‐5RA on human eosinophils according to the number of the eosinophils. We further examined the usability of soluble IL‐5RA (sIL‐5RA) in the serum as a novel biomarker for the diagnosis of eosinophil‐related diseases. When eosinophilic inflammation occurs, the concentration of sIL‐5RA in the blood is highly elevated. To diagnose eosinophilic inflammation, the aptasensor was calibrated in phosphate‐buffered saline (PBS) to detect sIL‐5RA. The detection limit of the aptasensor in PBS was 1.69 pg/mL, which is lower than that of commercially available ELISA kits. The dynamic range of the aptasensor was 10–10,000 pg/mL, with high specificity over other serum proteins and interleukin family members. The aptasensor was capable of distinguishing between patients with eosinophilic asthma (EA) and normal controls (NCs) based on serum sIL‐5RA levels. Consequently, the fabricated aptasensor will contribute to the development of novel diagnostic systems for IL‐5RA‐related diseases.
