英文摘要	in this work, we introduced a facile method for the construction of a polypyrrole/hemin (ppy/hemin) nanocomposite via one-pot chemical oxidative polymerization. in this process, a hemin molecule serving as a dopant was entrapped in the ppy nanocomposite during chemical oxidative polymerization. scanning electron microscopy (sem), transmission electron microscopy (tem), fourier transform infrared spectroscopy (ftir), and uv-visible spectroscopy results demonstrated that the ppy/hemin nanocomposite was successfully synthesized. the as-prepared nanocomposite exhibited intrinsic peroxidase-like catalytic activities, strong adsorption properties, and an excellent near-infrared (nir) light-induced thermal effect. we utilized the nanomaterials to catalyze the oxidation of a peroxidase substrate 3,3,5,5-tetramethylbenzidine by h2o2 to the oxidized colored product which provided a colorimetric detection of glucose. as low as 50 mu m glucose could be detected with a, linear range from 0.05 to 8 mm. moreover, the obtained nanocomposite also showed excellent removal efficiency for methyl orange and rhodamine b and a photothermal effect, which implied a promising application as the pollutant adsorbent and photothermal agent. the unique nature of the ppy/hemin nanocomposite makes it very promising for the fabrication of inexpensive, high-performance bioelectronic devices in the future.
