After COF-SSS extracting the analytes, high voltage electricity was applied and combined with ambient mass spectrometry (AMS) to achieved simultaneous detection within 1.5 min.

To investigate the reliability of this method, alachlor, metolachlor, acetochlor, pretilachlor, butachlore, napropamide, propachlor were detected. The results demonstrated that the simultaneous detection of the seven amide herbicides in astragalus sample can be realized using the method.

In this study, a sandwich-type electrochemical aptasensor for cTnI determination is constructed using reduced graphene oxide-tetraethylene pentaamine (rGO-TEPA) based on Au metal ion-modified carbon nanotubes (CNTs) as the substrate nanocomposite and Co3O4 nanoparticles doped with AuPt bimetallic nanoparticles, horseradish peroxidase (HRP), hemoglobin (hemin), and aptamer 2 (Apt2) (Co3O4/AuPt/HRP/hemin/Apt2) as the signal probe. The synergistic catalysis of the Co3O4/AuPt nanozymes and HRP/hemin biological enzymes can catalyze the decomposition of H2O2.

The electrochemical redox signals linearly increase with the logarithm of the cTnI concentration in the range 0.1 ~ 1.0 × 107 pg/mL with a limit of detection as low as 0.01 pg/mL.

Subsequently, without the need for additional steps, Co PBANaClO was obtained by simply mixing NaClO with Co PBA at room temperature. This fabrication process led to the formation of numerous Co nanoparticles on the surface of Co PBA, thereby exposing more active sites. Based on the exceptional peroxidase-mimicking activity exhibited by Co PBANaClO, we constructed the Co PBANaClO-luminol-H2O2 CL platform and successfully utilized it for the sensitive detection of both H2O2 and glucose, with detection ranges of 0.05-20 µM and 1-50 µM, respectively, and detection limits of 23 nM and 36 nM, respectively.

Structural and morphological characterization of the MOF onto the 3D-printed device was performed using X-ray powder diffraction, scanning electron microscopy, infrared spectroscopy, and fluorescence analysis. The key advantage of the presented device is its full compatibility with conventional fluorometers, requiring no instrumental modifications since it fits directly into a standard cuvette holder. Additionally, the ability to perform measurements directly in the solid state, minimizing matrix effects thanks to the 3D-printed device functionalized with the MOF, offers a significant improvement over traditional methodologies.
