TLDR
A strong antimicrobial activity against Escherichia coli of Cu-BTC metal-organic frameworks immobilized over cellulosic fibers is reported in this paper, where the in situ synthesis of MOF-199 or HKUST-1 is carried out by exposing carboxymethylated substrates to Cu(OAC)2, 1,3,5-benzenetricarboxylic acid and trie- thylamine solutions following a very specific order.Abstract:
A strong antimicrobial activity against Escherichia coli of Cu-BTC metal-organic frameworks immobilized over cellulosic fibers is hereby reported. The in situ synthesis of Cu-BTC metal-organic frameworks, aka MOF-199 or HKUST-1, onto cellulosic substrates was carried out by exposing carboxymethylated cellulosic substrates to Cu(OAC)2, 1,3,5-benzenetricarboxylic acid and trie- thylamine solutions following a very specific order. Using an in vitro model, in accordance to ASTM E2149-13a, we observed that the cellulose-MOF system was able to completely eliminate the growth of E. coli on agar plates and liquid cultures. The antibacterial activity of the comprising components of MOF-199 and the cellulosic substrate was also evaluated and determined to be negligible. Since the method used to synthesize MOF-199 crystals provides a strong bond between the crystals and the cellulosic substrates, the crystals not detach from the anionic cellulosic fibers allowing the modified textile to be washed and reused hence opening a new avenue to fabricate antibacterial clinical fabrics.

Metal-organic frameworks: mechanisms of antibacterial action and potential applications.
TL;DR: Metal-organic frameworks are porous, hybrid materials comprising metal ions linked by organic binding ligands that can act as a reservoir of metal ions, providing their gradual release and resulting in a sustained antibacterial action analogous to that proposed for metal/metal oxide nanoparticles but different to that of antibiotics.

Metal-Organic-Framework-Based Materials for Antimicrobial Applications.
TL;DR: In this paper, a review of metal-organic frameworks (MOFs) for various antimicrobial applications is presented, which are classified by their roles as component-releasing (metal ions, ligands, or both), photocatalytic, and chelation antimicrobial agents as well as carriers or/and synergistic antimacterial agents of other functional materials (antibiotics, enzymes, metals/metal oxides, carbon materials, etc.).
