Prolonged release of silver and iodine from ZIF-7 carrier with great antibacterial activity

Abstract

The study of substances with antibacterial properties has expanded greatly in recent years. There are few reports about antibacterial activity of Ag@MOFs and I2@MOFs. In this study, ZIF-7 was used...

The antibacterial activity of three zeolitic-imidazolate frameworks and zinc oxide nanoparticles derived from them

“…These studies have been a reconfirmation of the previous study of this research group on ZIF-7. 25 The release process of ZnO samples is similar to the ZIF samples derived from them, except for ZIF-4, where more Zn 2+ release was observed. This observation could be attributed to its uniform nanoparticle morphology with a narrow size distribution, which is expected to have higher solubility and zinc ion release according to the Gibbs–Thompson relation.…”

“…The synthesis method mentioned in the previous literature was employed for synthesizing this compound. 25 First, 0.946 g of benzimidazole in 20 mL of DMF and 0.878 g of Zn(CH 3 COO) 2 ·2H 2 O in 20 mL of distilled water were separately dissolved. Each solution underwent ultrasonic treatment for 5 minutes.…”

“…Manipulating these parameters during their synthesis can result in MOFs with completely different characteristics. This has led many researchers to study MOFs due to their wide range of potential applications, such as catalysts, 11 electrochemical and chemical sensors, 12 encapsulating large molecules, 13 enzymes, 14,15 storing gas, 16,17 removal of hazardous heavy metals, 18 organic dyes and toxins, 19–21 water splitting, 22 exhibiting anti-bacterial and anti-cancer activities, 23–26 facilitating drug delivery 27–30 and etc. MOFs can be used as a source for releasing metal ions under controlled conditions.…”

Ag@MUT-16 nanocomposite as a Fenton-like and plasmonic photocatalyst for degradation of Quinoline Yellow under visible light

“…This difference could be due to the presence of Ag NPs in Ag@ MUT-16 , which makes the final residue heavier. 21 TGA data reveals that about 39.3% (w/w) of Ag@ MUT-16 is made up of Ag NPs.…”

“…2 MOFs have intriguing characteristics such as high porosity, large surface area, crystalline structure, tunable pore structure, stable chemical and thermal properties, and ability to tune optical properties through organic ligands, metal nodes, and guest molecules. [1][2][3][4][5][6][7][8] Due to their fascinating properties, MOFs have applications in numerous fields, including gas storage/separation, [7][8][9][10][11] sensing, 12 drug delivery, [13][14][15][16][17][18][19][20] antibacterial agents, [21][22][23][24][25][26] templates, [27][28][29] catalysis, 30,31 and photocatalysis. 1,2,29,32,33 MOFs can be used for photocatalysis because of their metal centers and organic ligands.…”
