A Zn(II)-based coordination polymer: Fluorescence sensing property and treatment effect on Osteosarcoma by inducing autophagic programed cancer cell death

A Fluorescent Zn(II) Coordination Polymer: Sensitive Detection of Cr2O72- in Water and Prevention Activity On the Deep Vein Thrombosis in Orthopedic Nursing

A novel coordination polymer (CP) based on Zn(II) of [Zn(tptc)_0.5(bpy)(H₂O)]_n (1) was synthesized through utilizing the 2,2'-bipyridine (bpy) chelating N donors and p-terphenyl-2,2'',5'',5'''-tetracarboxylate acid (H₄tptc) as the co-ligands. The measurements of the fluorescence were implemented for the complex 1 in solution and solid state, and the result reveals that 1 has a strong fluorescence and it is a sensory material with great development space to determine the trace Cr₂O₇^2- (with the detection limit of 36 ppb) in the water solutions via applying the fluorescence quenching effect. As the common disease in the orthopedic nursing, the deep vein thrombosis was the objective in this research. The weigh and length of the thrombus in the animals were measured and analyzed. In addition to this, the inflammatory response in the deep vein thrombosis animal was evaluated by RT-PCR. Molecular docking results indicate that only the carboxyl group could provide polar oxygen atoms for the formed hydrogen bonds to the protein.
