Superhydrophobic nanosized metal–organic framework composites for the targeted removal of hydrophobic pharmaceuticals with outstanding bacterial anti-adhesion properties

Abstract

The increasing concentration of pharmaceutical waste in environmental water bodies after the COVID-19 pandemic has accelerated the urgency of removing various drugs from wastewater specimens. Realizing this concern, herein, for...

Naphthalimide functionalized metal–organic framework for rapid and nanomolar level detection of hydrazine and anti-hypertensive drug nicardipine

“…2a and b). 29 The vacant linker defect sites are occupied by six trifluoroacetate (modulator) anions for each Zr 6 cluster, which was proved by EDX (Fig. S4†) and 19 F NMR (Fig.…”

“…To quantify these missing linker defects in 1′ , we employed methodologies from reported literature. 29 It was calculated that the molecular weight of an ideal, dehydroxylated, solvent-free hexanuclear Zr 6 cluster was determined to be 4.4 times higher than that of six ZrO 2 unit. Calculations based on TGA (given in the ESI†) showed that the experimental plateau ( W Exp.…”

Superhydrophobic Metal–Organic Framework-Based Composite Featuring Removal of Hydrophobic Drugs and Pesticides and Antibacterial Activities

“…This newly developed adsorbent exhibited high adsorption capacity, even higher than the adsorption capacity reported in our previous work. 17 The previous fluorinated adsorbent from our group has an adsorption capacity of 86.5 and 148.0 mg/g for favipiravir and diflunisal, respectively. Meanwhile, for SHMOF′, the adsorption capacity for flurbiprofen drug and fluazinam pesticide is 435.3 and 575.6 mg/g, respectively.…”

“…We designed a fluorinated MOF to gain hydrophobicity and used the hydrophobic nature of that adsorbent to remove the hydrophobic drugs (favipiravir and diflunisal), but it has poor adsorption capacity. 17 To address the above-mentioned issue, we fabricated an ultrarobust, environmentally friendly MOF-based adsorbent (SHMOF′) with a long-chain hydrocarbon functionalization to gain hydrophobicity. As previously mentioned, numerous adsorbents are accessible for isolating hydrophilic drugs.…”

“…Recently, our group developed a fluorocarbon-functionalized MOF and Ag-nanoparticle-doped cotton composite to demonstrate antimicrobial properties. 17 Although it has potential antimicrobial properties, it loses its impact due to the fluorinated material.…”
