Antibacterial and anti-inflammatory ZIF-8@Rutin nanocomposite as an efficient agent for accelerating infected wound healing

“…With the explosive development of nanotechnology, nanomaterials may represent a promising candidates for the treatment of antibacterial ( Vimbela et al, 2018 ). Metal-Organic Frameworks (MOFs) are coordination polymers with intramolecular pores formed by the self-assembly of organic ligands and metal ions through coordination bonds ( Chai et al, 2021 ).…”

“…Nevertheless, the components of the organic ligand and metal ions generally produce reactive oxygen species (ROS) to act as bactericidal agents. While the excess ROS could cause inflammation in surrounding healthy tissues and organic ligand is toxicity ( Vimbela et al, 2018 ; Li et al, 2019a ; He et al, 2020 ). Due to the potential inflammatory weakness, which is undesirable for the wound healing process, endowing ZIF-8 with the characteristics of scavenging excess ROS or anti-inflammatory effect during the sterilization process is advantageous.…”

Understanding gold toxicity in aerobically-grown Escherichia coli

“…Given their toxicity, a number of these non-essential metals are currently being used as antimicrobial compounds by incorporating them on surfaces and coatings medical and pharmaceutical equipment [4]. Particularly, and since silver, gold, copper and titanium exhibit physicochemical characteristics favoring their antimicrobial activity, they are nowadays usually included in several nanomaterials [5]. The toxicity of some metals and metalloids such as chromate and tellurite is related to the generation of reactive oxygen species (ROS) [6][7][8][9][10], which then damage key cell components and affect bacterial growth [11].…”

“…Currently, nanostructures (NS) containing some of these non-essential metals are used in diverse applications such as water treatment, photocatalysis, optics and therapeutic procedures, among others [5,17]. In particular, gold nanostructures (AuNS) behave as potent antimicrobial agents against multidrug resistant Gram-negative and Gram-positive bacteria [18].…”

Photothermal-enhanced antibacterial and antioxidant hydrogel dressings based on catechol-modified chitosan-derived carbonized polymer dots for effective treatment of wound infections

“…In order to obtain desired antibacterial activity, decorating a hydrogel network with conventional metal, metal oxide nanoparticles (NPs) or antibiotics is a commonly used approach. [15][16][17] However, the potential nonspecific biological toxicity of metal or metal oxide NPs may cause severe health problems, 18,19 and the overuse of antibiotics would lead to drug-resistant bacteria that have to be treated with more powerful medicines. 20,21 Currently, carbon dots (CDs) attract tremendous attention as novel nano-antibacterial agents and have been integrated into hydrogels, due to their simple manufacturing process, low toxicity, excellent water solubility and a special antibacterial mechanism that conduces to avoid the emergence of drug-resistant bacteria.…”
