Summary: Graphdiyne-based materials show great potential for adsorption and detection of heavy metal ions due to strong interactions between acetylenic links in graphdiyne and some metal ions. The introduction of N atoms in graphdiyne greatly improves the electrochemical performance, and the signal intensity is closely related to the number of detection sites. The TGDY-based electrochemical sensor demonstrates satisfactory selectivity, reproducibility, stability, and applicability for detecting Cd2+ and Pb2+ in water.

Summary: A novel smartphone-based electrochemical cell sensor was developed to evaluate the toxicity of heavy metal ions on Hep G2 cells. The sensor utilized RGO/MoS2 composites to improve adaptability and amplify signals, showing dose-dependent reductions in cell viability by Cd2+, Hg2+, and Pb2+. Synergistic effects were observed between Cd2+ and Pb2+ and between Hg2+ and Pb2+, while antagonistic effects were found between Cd2+ and Hg2+, and in ternary mixtures of Cd2+, Hg2+, and Pb2+. The new sensor provided a more convenient and sensitive toxicity assessment strategy compared to traditional methods.

Summary: Functionalization of mesoporous silica nanoparticles (MSNs) with amine and thiol-based groups improved their efficiency. The existence of amine and thiol on the surface of MSNs was confirmed using FTIR, TEM, and SEM techniques. The performance of polysulfone (PS) nanofiltration membranes incorporated with surface-modified MSNs was evaluated, and the membrane with amine and thiol-based MSNs showed the highest pure water permeability. This research highlights the potential application of these surface-modified MSNs/PS nanofiltration membranes for the removal of heavy metal ions from polluted water.

Summary: This article investigates the efficiency of metal-organic frameworks (MOFs) in detecting heavy metal ions such as Pb2+, Hg2+, and Cd2+. By optimizing conditions, MOFs composite materials and membranes can achieve ultra-sensitive detection of Pb2+ ions (LOD in pmol/L), which is their main advantage. However, the low working potential of MOFs requires the development of MOFs membrane composite materials for highly efficient detection of toxic Pb2+ ions. Therefore, this review summarizes their advantages, limitations, and future directions.

Summary: A novel radioiodination method using carboxylic acids as radiolabeling precursors is developed. This method efficiently radiolabels (hetero)-arenes and cinnamic and phenylpropiolic acids through decarboxylation and formation of organogold-(I) intermediate. Additionally, the prolonged stability and enduring radiolabeling capabilities of crude gold-(I) organometallic compounds are demonstrated.
