Summary: This work presents the targeted modification of carbon paste (CP) by adding conductive graphene oxide (GO) and mesoporous natural zeolite with Ni2+ cations (NiZ), which enhances the electrocatalytic properties. A univariate optimization showed that 5% (w/w) of NiZ and GO in the CP led to a threefold increase in peak current, decreased overpotential of paracetamol (PAR) oxidation, low background current, and high signal-to-noise ratio. The CPE/NiZ/GO sensor exhibited a linear response in the PAR concentration range of 0.004 to 0.12 mg L-1, with a low limit of detection of 0.0012 mg L-1 (0.0078 μM) and high stability (RSD = 3%). The proposed method demonstrated good selectivity and robustness to interference, and was successfully applied for the determination of PAR in pharmaceuticals, human urine, and serum.

Summary: This research presents the development and electroanalytical performance of a novel carprofen voltammetric carbon paste electrode (CPEs). The electrode matrix is fortified with zeolite nanostructures, resulting in an effective electrocatalytic activity that facilitates the oxidation of carprofen molecules. The proposed electrooxidation mechanism involves the oxidation of the enamine N atom through the transfer of delocalized lone pair of electrons, along with the participation of one proton. The utilization of ZY/CPEs allows for simultaneous quantification of carprofen in the presence of various interferents and degradation products, with high sensitivity and selectivity. The presented voltammetric analytical technique exhibits comparable recovery values compared to official chromatographic techniques for monitoring carprofen residues in veterinary and biological samples.

Summary: PPy.SDS-coated carbon fiber electrodes demonstrated enhanced drug sensing capabilities compared to bare carbon fibers, with a 14-fold increase in electrochemical surface area. The use of a large counter anion as dopant, such as dodecyl sulfate, resulted in a greater drug sensing response. Differential pulse voltammetry (DPV) with PPy.SDS fiber electrodes was able to detect paracetamol with a detection limit of 34 μM and a linear response range of 50-500 μM, even in the presence of interferents like dopamine and ascorbic acid at 100 μM concentrations. This indicates the potential for real-world applications of PPy.SDS electrodes in drug sensing, with the ability to detect anti-psychotic medication like clozapine at low concentrations.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.
