Facile synthesis of ZnO QDs@GO-CS hydrogel for synergetic antibacterial applications and enhanced wound healing

Recoverable peroxidase-like Fe3O4@MoS2-Ag nanozyme with enhanced antibacterial ability

“…Therefore, enormous attention has been paid to urgent developing various antibacterial agents with broad-spectrum antimicrobial property and minor side effect [3] . As with the development of nanotechnology, noble metals, especially Ag nanoparticles, have been widely applied due to their potent antibacterial properties dominated by local releasing metal ions [4] , [5] . Nevertheless, the effective application has been limited by the easy aggregation of small nanoparticles, which requires suitable matrix for accurate design of the nanoparticle loading.…”

The In Vivo, In Vitro and In Ovo Evaluation of Quantum Dots in Wound Healing: A Review

“…Generally, the antibacterial properties of QDs were analyzed using a plate counting method to calculate the colony-forming unit (CFU) of remaining bacteria after exposure to the particular treatment modalities and morphological studies on bacteria were conducted to compare the bacterial structure pre- and post-treatment. When the bacteria were exposed to QDs, the microbial membrane disrupt due to the high production of reactive oxygen species (ROS) which triggers significant lipid peroxidation on membrane [ 57 ]. The combination of QDs with polymer deems to have high antibacterial properties towards micro-organisms e.g., S. aureus even inhibits the growth of different drug-resistant bacteria e.g., Methicillin-resistant Staphylococcus aureus (MRSA) [ 60 ].…”

“…QDs tend to have higher antimicrobial properties when they are in an excited state or exposed to light radiation as an example Liang et al, 2019 have tested zinc oxide quantum dots in both excited and normal state. The result was antibacterial rates and production of reactive oxygen species (ROS) were significantly higher in an excited state than normal state [ 57 ]. The photoactivated QDs produce more radicals that cause accumulation of ROS inside the cells which inhibit respiration and replication of microbes [ 64 ].…”

Self‐healing Polyol/Borax Hydrogels: Fabrications, Properties and Applications

“…[93][94][95] Other types of nanoparticles which can be used to create various properties in hydrogels include electroconductive agents (electroconductive polymers, carbon nanotubes (CNT) and graphene), [96][97][98] antibacterial nanofillers (such as nanoparticles of Ag, ZnO, and Cu), [99] and quantum dots. [100] Moreover, addition of other ingredients to the boraxbased nanocomposite hydrogels have been evaluated for the fabrication of hybrid materials. For instance, addition of metal cations (such as Zn 2 + ) [61] can create supercapacitors or addition of polyphenols [63][64][65] can enhance the adhesivity and endow antioxidant property to the hydrogel.…”
