A novel nonenzymatic electrochemiluminescence (ECL) sensor based on the perovskite LaTiO3-Ag0.1 nanomaterial is developed. The sensor displays high electrocatalytic activity with a linear range from 0.01 mu M to 0.10 mM (R = 0.9999), a detection limit of 2.50 x 10(-9) M (SIN = 3), and a sensitivity of 7.80 x 10(2) mu AmM-1 cm(-2). Furthermore, it is successfully utilized for the detection of glucose in real blood samples. The results indicate that the perovskite LaTiO3-Ag0.1 nanocomposite is promising in electrochemical sensing and biosensing.
