“…Differences in polarity between complexes and ligands contribute significantly to their varied activity, particularly in interactions with bacterial cell walls. Far et al 50 noted that a highly polar ligand displayed superior activity against S. aureus and E. coli , resulting in larger inhibition zones (45.3 and 39 mm, respectively), suggesting the influence of ligand polarity on its efficacy. In contrast, Mirdarvatan et al 51 found that although a ligand exhibited activity against both bacteria, the corresponding vanadium complex lacked significant activity against S. aureus at a dose of 40 mg/ml, likely due to structural differences affecting bacterial interaction.…”

From the perspective of possible antiviral and antibacterial activity of vanadium‐based complexes, we report the synthesis of new Schiff base ligand (L4) and a new Schiff‐base‐vanadium complex (C2). Both the ligand and the complex were characterized by Fourier transform infrared spectroscopy and Nuclear magnetic resonance techniques. Single‐crystal X‐ray Diffraction analysis has been used to confirm the structure of ligand L4 and complex C2. In addition, L1–4 and C1–3 were tested for their antibacterial effects against Escherichia coli and Staphylococcus aureus. Among the compounds, L2 demonstrated the most potent inhibition of both bacteria, exhibiting the lowest values for minimum inhibitory concentration (CMI) and minimum bactericidal concentration (CMB) (CMI = 0.16, CMB = 0.31 against E. coli, and CMI = CMB = 0.16 against S. aureus). Additionally, L2 produced the largest inhibition zones with diameters of 15.5 ± 0.15 against E. coli and 14.5 ± 0.04 against S. aureus. Furthermore, the antiviral efficacy of L1, L2, L4, C1, C2, and C3 against RNA viruses was assessed. C2 and C3 exhibited the most potent antiviral activity among the tested compounds.

“…PEG is a commonly used biologically compatible agent to modify nanoparticle surfaces, and it is used as an organic molecule for cell recognition and to assist in membrane transport; , here, it facilitates the import and export of bionanorobots from cells. The Schiff base is the most intelligent part of the bionanorobot, as it can detect and bind to zinc ions to remove them from the cells . Moreover, the Schiff base also works as a fluorescent probe, and it fluoresces after specifically recognizing Zn 2+ .…”

Nanorobots hold great promise for integrated drug delivery systems that are responsive to molecular triggers. Herein, we successfully developed an automatic smart bionanorobot that has transport capability and recognizes and removes zinc ions from poisoned cells based on nanoscale polyhedral oligomeric silsesquioxane molecules. This intelligent bionanorobot can easily move inside and outside the cell and find zinc ions owing to its highly selective recognition to zinc ions and high cell permeability, especially the well-combined high penetration and strong binding energy. More importantly, it was also found that this intelligent bionanorobot can restore round HeLa cells to a normal fusiform cell morphology following high-concentration zinc treatment and does not interfere with cell proliferation and division. It was also shown by in vivo experiments that the bionanorobot can inhibit persistent enlargement of the liver caused by zinc ion poisoning.
