Post-synthesis introduction of dual functional groups in metal–organic framework for enhanced adsorption of moxifloxacin antibiotic

Nanoporous Metal–Organic Framework Adsorbent Constructed via Ligand Tailoring for Rare-Earth Metal Ion Recovery

“…As shown in the FTIR spectra (Figure a), the presence of free carboxyl groups is confirmed by the peaks at 1707 cm –1 . Upon increasing the amount of H 1 linker, this sign is weakened gradually, which confirms the substitution of the H 2 linker by the H 1 linker.…”

“…As shown in the FTIR spectra (Figure 1a), the presence of free carboxyl groups is confirmed by the peaks at 1707 cm −1 . 33 Upon increasing the amount of H 1 linker, this sign is weakened gradually, which confirms the substitution of the H 2 linker by the H 1 linker. The peaks near ∼1580 and ∼1400 cm −1 are attributed to the asymmetric and symmetric stretching vibrations of the coordinated carboxylates.…”

2D Fluorinated Graphene Oxide (FGO)-Polyethyleneimine (PEI) Based 3D Porous Nanoplatform for Effective Removal of Forever Toxic Chemicals, Pharmaceutical Toxins, and Waterborne Pathogens from Environmental Water Samples

“…As we have discussed before, antibiotic contamination is a serious concern for society due to its association with adverse health effects such as the formation of antibiotic-resistant genes. − It can cause several health problems such as immunity decline, genetic defects, and cancer. − As a result, there is an urgent need to design a novel system that has the capability for the detection and removal of antibiotics from environmental samples. − Next, to find out the capturing and separating efficiency of tetracycline and moxifloxacin antibiotics from environmental samples using the FGO-PEI based nanoplatform, we performed the following experiments. Initially, we infected the drinking water samples with tetracycline and moxifloxacin antibiotics selectively and simultaneously.…”

“…The number of live bacteria was counted in the water samples with a colony counter after 24 h at 37 °C incubation, as we have reported before. − , Details are reported in the Supporting Information.…”

“…According to the UN and WHO, every 2 min, a child dies from a water-borne illness in this world. ,− On the other hand, about 7.2 million Americans get sick every year from diseases spread through waterborne pathogens. ,− Because of the low infectious dose, disease transmission is facilitated heavily via the outbreaks of diarrhea, cholera, and typhoid. ,− Recent reports indicate that direct costs of all illnesses caused by waterborne microorganisms are around $3.3 billion/year caused by 17 pathogens. ,− Several antibiotics such as fluoroquinolone, tetracycline, fluoroquinolone, etc., are present in aquatic environments and drinking water. − Recently, several reports indicated that antibiotic residues in water can produce antibiotic-resistant bacteria, which are a serious threat for our society. − To tackle the challenges, scientists are designing a novel adsorbent-based technology that has the potential to improve access to safe drinking water by removing chemical and biological toxins. − …”
