Recent antioxidative nanomaterials toward wound dressing and disease treatment via ROS scavenging

Natural N-Doped Carbon Quantum Dots Derived from Straw and Adhered onto TiO2 Nanospheres for Enhancing the Removal of Antibiotics and Resistance Genes

“…Indirectly, photocatalysis-produced ROS was mainly responsible for ARG degradation. 26,27 A series of nearly spherical N-SCQDs with a uniform size by typical high-resolution transmission electron microscopy (HR-TEM) images (Figure 3a) were successfully anchored onto the surface of the TiO 2 nanospheres. N-SCQDs obtained at 170, 230, and 290 °C had average diameters of ∼20, ∼10, and ∼2 nm, respectively.…”

“…As explained previously, this reduction occurred because oxidants such as ROS produced by indirect photolysis preferentially reacted with guanine bases in the DNA. Indirectly, photocatalysis-produced ROS was mainly responsible for ARG degradation. , …”

Antibacterial hydrogel dressings and their applications in wound treatment

“…If a prolonged period of the inflammation phase unfolds, then an acute wound may be classified as a chronic wound, which often experience a postponed and incomplete healing process (Jones et al, 2018, Maaz Arif et al, 2021. Wound healing can be delayed by the presence of intrinsic and extrinsic factors including the lack of nutrition, pathogenic infections, co-morbidities, medications, or inappropriate wound dressing selection or management (He et al, 2022, Nosrati et al, 2021. When the defensive skin integrity is compromised in an open wound, it allows the invasion of pathogenic microorganisms, causing local infections or even sepsis (Duan et al, 2022, Chelkeba andMelaku, 2021).…”

A double-edged sword: ROS related therapies in the treatment of psoriasis

“…Therefore, the treatment of Ps based on antioxidant stress is considered to be feasible. Currently, many studies have reported the treatment of Ps based on relieving OS [ 34 , 35 ].…”
