<i>In situ</i> deposition of MOF199 onto hierarchical structures of bamboo and wood and their antibacterial properties

Infectious diseases are a major public health concern globally. Infections caused by pathogens with resistance against commonly used antimicrobial drugs or antibiotics (known as antimicrobial resistance, AMR) are becoming extremely difficult to control. AMR has thus been declared as one of the top 10 global public health threats, as it has very limited solutions. The drying pipeline of effective antibiotics has further worsened the situation. There is no absolute treatment, and the limitations of existing methods warrant further development in antimicrobials. Recent developments in the nanomaterial field present them as promising therapeutics and effective alternative to conventional antibiotics and synthetic drugs. The metal–organic framework (MOF) is a recent addition to the antimicrobial category with superior properties. The MOF exerts antimicrobial action on a wide range of species and is highly biocompatible. Additionally, their porous structures allow the incorporation of biomolecules and drugs for synergistic antimicrobial action. This review provides an inclusive summary of the molecular events responsible for resistance development and current trends in antimicrobials to combat antibiotic resistance and explores the potential role of the MOF in tackling the drug-resistant microbial species.

“…However, the large number of carboxyl-copper (II) complex would initiate the rapid nucleation of MOF, which lead to a quick precursor consumption and relatively small-sized MOF crystals on bamboo surface (Fig. 2h) (Su et al 2019).…”

“…However, the main drawback of bamboo is that it is susceptible to bacteria and fungi, as for its rich nutrients content (Li et al 2019;Zhang et al 2020). Recently, MOF/woody composites materials have been used in several antibacterial applications (Su et al 2019). MOF199, which consist of copper (II) ions and 1,3,5-benzentricarboxylic acid (BTC), has been proved to with powerful antibacterial activity on textile fabric (Ma et al 2018;Wang et al 2015).…”

“…The copper (II) in MOF199 can denature proteins and fatty acids in bacterial cell membrane or change transmembrane potential, leading to cell rupture and death (Wyszogrodzka et al 2016). In our previous work, we successfully deposited MOF199 on the surface of moso bamboo, and the obtained materials exhibited good antibacterial activity against both Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) (Su et al 2019). However, due to the weakness of physical deposition between MOF and bamboo, MOF easily disengaged from the bamboo surface and limited its application.…”

Bamboo, as a fast-grown forest resource, could be functionalized by metal-organic frameworks (MOF) with various potential applications. However, the stability of MOF immobilized on bamboo surface remains to be improved. In this work, MOF199, as known as HKUST-1, was in situ anchoring on moso bamboo via regulating pretreatment of bamboo and a green two-step synthesis route. The two-step synthesis route could be completed under room temperature and both precursor solutions can be reused. The results indicated that, with the collaboration of deligni cation and carboxymethylation pretreatment of bamboo, a dense and well-dispersed MOF199 coating was successfully synthesized, the adhesion between MOF and bamboo surface was also improved. Besides, the quantity and size of MOF199 on bamboo can be tailored by adjusting the carboxyl groups of pretreated bamboo and the concentration of copper nitrate solution. More importantly, results show that the formation of carboxyl-copper (II) complex served as nucleation sites for the growth of MOF199 crystals is the key to prepare uniform MOF layers.The growth of MOF199 endow bamboo with good antibacterial activity against E. coli. This method provides a facile and practical strategy for designing MOF coated woody materials.

“…The corresponding wood/MOF composites were demonstrated to have high removal efficiency for organic pollutants, 23 superior selectivity toward CO 2 adsorption against N 2 , 24 and good antibacterial activities. 25 Furthermore, carbonization of wood-/cobalt-based MOF composites produced a high-power 3D monolithic reactor for improved mass transfer and CO conversion during Fischer–Tropsch synthesis. 26 These composites have combined the functionalities of MOFs and mechanical robustness of wood.…”

Mechanical stability and multicycle durability are essential for emerging solid sorbents to maintain an efficient CO 2 adsorption capacity and reduce cost. In this work, a strong foam-like composite is developed as a CO 2 sorbent by the in situ growth of thermally stable and microporous metal-organic frameworks (MOFs) in a mesoporous cellulose template derived from balsa wood, which is delignified by using sodium chlorite and further functionalized by 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-mediated oxidation. The surface carboxyl groups in the TEMPO-oxidized wood template (TO-wood) facilitate the coordination of the cellulose network with multivalent metal ions and thus enable the nucleation and in situ growth of MOFs including copper benzene-1,3,5-tricarboxylate [Cu 3 (BTC) 2 ], zinc 2-methylimidazolate, and aluminum benzene-1,3,5-tricarboxylate. The TO-wood/Cu 3 (BTC) 2 composite shows a high specific surface area of 471 m 2 g –1 and a high CO 2 adsorption capacity of 1.46 mmol g –1 at 25 °C and atmospheric pressure. It also demonstrates high durability during the temperature swing cyclic CO 2 adsorption/desorption test. In addition, the TO-wood/Cu 3 (BTC) 2 composite is lightweight but exceptionally strong with a specific elastic modulus of 3034 kN m kg –1 and a specific yield strength of 68 kN m kg –1 under the compression test. The strong and durable TO-wood/MOF composites can potentially be used as a solid sorbent for CO 2 capture, and their application can possibly be extended to environmental remediation, gas separation and purification, insulation, and catalysis.
