- Abstract
Mesoporous dysprosium oxide microspheres were prepared by using a hydrothermal process and applied as a dynamic sensor for the detection of hydrogen peroxide (H2O2), owing to its high sensitivity in H2O2 electroreduction. Infrared microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, and nitrogen adsorption-desorption isotherms were employed to study the porous structure and surface properties of the samples. The detection performance pertains to a broad linear range (1-400 μ m, R=0.989), high sensitivity at 19.7 μA m m−1, measurement limit at 1 μ m (signal-to-noise=3), along with the quick response to meet a 95 % plateau current within 3 s. The dynamic detection of H2O2 released from living breast cancer cells under pro-inflammatory stimulation was also recorded in real time.
