A novel nonenzymatic ECL glucose sensor based on perovskite LaTiO_3-Ag0.1 nanomaterials

摘要

A novel nonenzymatic electrochemiluminescence (ECL) sensor based on the perovskite LaTiO_3-Ag0.1 nanomaterial is developed. The sensor displays high electrocatalytic activity with a linear range from 0.01 μM to 0.10mM (R=0.9999), a detection limit of 2.50×10~(-9)M (S/N=3), and a sensitivity of 7.80 × 10~2 μA mM~(-1) cm~(-2). Furthermore, it is successfully utilized for the detection of glucose in real blood samples. The results indicate that the perovskite LaTiO_3-Ag0.1 nanocomposite is promising in electrochemical sensing and biosensing.
