Summary: The proliferation of heavy metal ions in water is a serious problem that is escalating. Rapid detection of these ions in an aqueous solution is of immense significance. To address the growing concentration of heavy metal ions, a facile and cost-effective sensing scheme based on intensity modulation is proposed. The scheme, comprising of a smartphone, light source, and analyte, can detect heavy metal ions at ppb level with an average limit of detection (LOD) of approximately 0.5 ppb. Additionally, the scheme shows a recovery level of approximately 95% when assessing spiked tap water, indicating its applicability. Overall, this sensing scheme with minimal logistics has the potential to replace complex analysis procedures using bulky and sophisticated instruments.

Summary: The effects of hydrazones and Schiff bases derived from isatin on the in vitro aggregation of beta-amyloid peptides (A beta) were investigated. The ligands showed a large affinity binding to A beta, particularly to A beta 1-16, and interacted mainly with His6, His13, and His14 residues at the metal binding site of the peptide. Additionally, these oxindole-derived ligands efficiently chelated copper(II) and zinc(II) ions, which explained their efficient inhibition of A beta fragments aggregation.

Summary: A methodology combining a conductive three-dimensional graphene framework and a rotating magnetic field is proposed to induce functional neuronal differentiation of bone marrow mesenchymal stem cells (BMSCs). The study demonstrates that a wireless electrical signal can be generated on the surface of the graphene framework by cutting magnetic field lines, leading to neuronal differentiation of BMSCs. Animal experiments confirm the neural differentiation of BMSCs on the graphene framework after transplantation in vivo with external rotating magnetic field stimulation. This study overcomes the lack of autologous neural stem cells in adult neurodegeneration patients and provides a simple and safe strategy for inducing neural differentiation of BMSCs with potential clinical applications in neural tissue engineering.
