Unique BiFeO₃/g-C₃N₄ mushroom heterojunction with photocatalytic antibacterial and wound therapeutic activity

Abstract

Bacterial infections have become a major problem threatening public health, and it is of great significance to treat wound infections in biological systems caused by bacteria. However, the traditionally used...

Integrated Biochip–Electronic System with Single-Atom Nanozyme forinVivoAnalysis of Nitric Oxide

“…The wounded mouse model is established based on our previous work, which investigated photocatalytic antibacterial and wound therapeutic activities. 36 A printed sensor with a flexible substrate was placed on the wound of the nude mouse, and ACh was then added on the wound to stimulate NO production. As shown in Figure 6c, an increase in the current can be observed when ACh was added, indicating that NO was successfully captured and catalyzed by the Co@CNT-PP sensor.…”

“…In this regard, the designed IND Co‑SAE is further applied for in vivo evaluation of the NO concentration produced by both the wounded and normal nude mice (Figure b). The wounded mouse model is established based on our previous work, which investigated photocatalytic antibacterial and wound therapeutic activities . A printed sensor with a flexible substrate was placed on the wound of the nude mouse, and ACh was then added on the wound to stimulate NO production.…”

Photocatalytic antibacterial agents based on inorganic semiconductor nanomaterials: a review

“…12b). 83 Furthermore, the ratio of BiFeO 3 /g-C 3 N 4 was regulated to control the decomposition of hydrogen peroxide for the generation of ROS ( • OH and • O 2 − ). As a result, BiFeO 3 / g-C 3 N 4 with a ratio of 10% exhibited enhanced antibacterial ability against E. coli and S. aureus when compared to the other controls.…”

Synergizing the internal electric field and ferroelectric polarization of the BiFeO3/ZnIn2S4 Z-scheme heterojunction for photocatalytic overall water splitting

“…Unfortunately, BiFeO 3 Z-scheme heterojunction photocatalysts for overall water splitting are still difficult to achieve due to their intrinsic sluggish dynamics. Although BiFeO 3 particulate as photocatalyst and photoelectrocatalyst for half-reaction water splitting has been already reported, with assistance from polarization modulation or heterojunction hybrid assemblage, 28,29 synergistic effect between ferroelectric polarization and internal electric eld for efficient photocatalytic overall water splitting without any sacricial agent and cocatalysts has never been realized to date and still remains a signicant basic science challenge. ZnIn 2 S 4 has been veried as an effective visible light photocatalyst to achieve hydrogen evolution from water.…”
