Two novel coordination polymers and their hybrid materials with Ag nanoparticles for non-enzymatic detection of glucose

Employing a rigid 6-(3-pyridyl)isophthalic acid (H(2)PIAD) linker, two novel coordination polymers (CPs), Nn(PIAD)](n) (1) and [Pb(HPIAD)(NO3)](n) (2) were synthesized and characterized. The hybrid of Ag nanoparticles (NPs) with compound 1 (Ag@1) was further modified onto electrode for the detection of glucose. The results demonstrated that Ag@1 possessed high sensitivity (0.156 mu A mu M-1 cm(-2)) and low detection limit (1.6 mu M) towards glucose sensing in the range of 5-3500 mu M. With the significant electrochemical performance, this work promotes the proposed strategy for CPs-based hybrid composites as sensing application.
