Summary: The study demonstrates the successful electrochemical sensing of Hg(II) in aqueous solution using nanoassembly based on cationic cyclodextrin carbon nanotubes (CNT-CDs) and ferrocenylcarnosine (FcCAR). The CNTs were functionalized with beta-cyclodextrins (CDs) through a click chemistry reaction and subsequent reduction of residual nitrogen groups. The CNT-CDs were cast on screen-printed carbon electrodes (SPCEs) and their electrochemical response was evaluated using cyclic voltammetry (CV). The CNT-CD/FcCAR nanoassembly showed enhanced electroactive properties for Hg(II) detection. The sensor exhibited a linear concentration dependence in the range of 1-100 nM, with a sensitivity of 0.12 muA/nM, a limit of detection of 0.50 nM, and a limit of quantification of 1 nM.

Summary: In order to successfully translate targeting nanomedicines from bench to bedside, it is necessary to address the common issues of rapid clearance and off-target accumulation. This phenomenon, known as protein corona (PC) formation, occurs when targeting nanoparticles encounter the bloodstream and interact with plasma proteins. The present review discusses the impact of PC on the biological behavior of targeting nanomedicines, as well as the best simulated environment and latest characterization techniques for PC analysis. The article also highlights recent progress in manipulating nano-bio interfaces to achieve optimal therapeutic outcomes.

Summary: Heteroatom-doped carbon nitride (C3N4) materials were investigated as supports for Au nanoparticles, which were anchored on sulfur-doped carbon nitride nanosheets (AuNPs@SCNN) and used as a catalyst for arsenic electroreduction. The synthesis of novel SCNN was achieved through a simple thermally induced copolymerization route using ammonium persulfate (APS) as a sulfur source. The integration of SCNN with AuNPs improved the assembly quality and interface, leading to enhanced catalytic activity. The composite (AuNPs@SCNN/GCE) modified glassy carbon electrode exhibited enhanced electrochemical responses for the electrocatalytic reduction of arsenic.

Summary: We reported a novel electrochemical sensor for the indirect determination of cyanuric acid (CA) using the complex formation between CA and melamine (MEL) for the first time. The sensor utilized the electrochemical conversion of MEL to electroactive polymelamine, with the decline in current intensity upon the addition of CA serving as the sensor response. A calibration curve was constructed using square wave voltammetry, with a limit of detection of 80.28 mu mol L-1. The proposed method showed excellent recovery range (91.2-101.0%) for real sample analysis.

Summary: In this research, the complexation of a newly synthesized covalent organic framework (schiff base network1) with different cations, including Hg2+, was studied. The results showed that schiff base network1 had a stronger interaction with Hg2+ compared to other cations, making it a potential ionophore for the development of a Hg2+ potentiometric sensor. A Hg2+ selective PVC membrane coated graphite electrode was successfully created using schiff base network1, which exhibited excellent response and sensitivity for the detection of Hg2+ in a wide range of concentrations. The electrode also demonstrated good performance in non-aqueous environments and had a long lifespan.

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.
