Synthesis of flower-like MoS/CNTs nanocomposite as an efficient catalyst for the sonocatalytic degradation of hydroxychloroquine.

Contamination of water resources by pharmaceutical residues, especially during the time of pandemics, has become a serious problem worldwide and concerns have been raised about the efficient elimination of these compounds from aquatic environments. This study has focused on the development and evaluation of the sonocatalytic activity of a flower-like MoS/CNTs nanocomposite for the targeted degradation of hydroxychloroquine (HCQ). This nanocomposite was prepared using a facile hydrothermal route and characterized with various analytical methods, including X-ray diffraction and electron microscopy, which results confirmed the successful synthesis of the nanocomposite.

A PCR-free genosensing platform for detection of Shigella dysenteriae in human plasma samples by porous and honeycomb-like biochar decorated with ultrathin flower-like MoS nanosheets incorporated with Au nanoparticles.

Shigella dysenteriae, a gram-negative bacterium, which results in the most infectious of bacterial shigellosis and dysenteries. In this study, an innovative gene detection platform based on label-free DNA sequences was developed to detect Shigella dysenteriae in human plasma samples. The porous and honeycomb-like structure of biochar (BC) was first synthesized through a pyrolysis process.

Ratiometric visual detection of tetracycline residues in milk by framework-enhanced fluorescence of gold and copper nanoclusters.

We reported a novel dual-emission fluorescence probe fabricated by encapsulating both gold (AuNCs) and copper nanoclusters (CuNCs) into zeolitic imidazolate framework-8 (ZIF-8). Obtained composite (AuCuNCs@MOF) was utilized for ratiometric determination of Tetracycline (Tcy) antibiotic. Under excitation at 400 nm, the AuCuNCs@MOF composite displayed two emission peaks at 520 and 650 nm which were originated from AuNCs and CuNCs, respectively.

Synthesis of g-CN@CuMOFs nanocomposite with superior peroxidase mimetic activity for the fluorometric measurement of glucose.

Herein, a novel metal-organic framework (MOF) based nanocomposite with efficient catalytic behavior is reported including flake-like copper (II) MOF (CuMOF) and graphitic CN nanosheets (g-CN). The g-CN@MOF nanocomposite was simply prepared by solvothermal synthesis of CuMOF in the presence of g-CN. The characterization analyses using scanning electron microscopy (SEM), X-ray diffractometry (XRD) and some other techniques demonstrated a nano-porous flake-like structure for the synthesized CuMOF, which enveloped the g-CN nanosheets.
